Are Fluorescent & LED Lights Making You Tired?
Did you know: some of the lights you have in your house are damaging your mitochondria (and thus adding to your fatigue)?Your mitochondria are so attuned with your environment that even the types of light you are exposed to each day can cause fatigue! The "bad" light I'm referring to here is a modern-day invention. Some refer to it as junk light. Others as white or blue light.The mitochondrial damaging light is a recent development for the human species. I'm referring specifically to compact fluorescent bulbs and the new LED (light emitting diode) bulbs - yes those same ones that last for years and years. These bulbs contain specific wavelengths of light that are particularly damaging to your mitochondria.And as I hope you know, underfunctioning and/or damaged mitochondria results in fatigue.Your body on lightYour ancestors had been exposed to the same type of light (the sun) for millions of years. (1) Millions of years! That is an incredibly long time for your body to adapt to one type of light. Through the sun, your mitochondria are best able to absorb and utilize light. They struggle when exposed to modern-day lighting.The compact fluorescent light was invented in 1976 and made its way into houses and offices in the 1980s. (2) Compact fluorescent bulbs are the spiral bulbs like the one found in the picture at the top of this post. The fluorescent tube lights - the ones you commonly see in office spaces - began being sold in 1938. Making their way into most offices by the 1950s. (3)LEDs (light emitting diodes) are the most recent lights to enter the commercial market. They were developed in the 1990s and only became affordable in the past few years. (4) LEDs are adored for their long lifespan - lasting ten times longer than incandescent bulbs. More recently, it's these bulbs that come enabled with wifi; allowing you to adjust the brightness with your phone.For millions of years, your ancestors were only exposed to the wavelengths of light put forth by the sun. In the early 1900s, the incandescent light bulb changed that. Humans were able to illuminate the dark. Fortunately, the wavelengths found in the incandescent light bulb were not too far off from that of the sun.It is the compact fluorescent (CFL) and LED bulbs that affect your mitochondria in a very bad way. These lights lack the wavelengths/frequencies found in natural sunlight. The infrared, red, and violet wavelengths found in sunlight are completely eliminated from LEDs and CFLs. And the blue light frequency has been amplified.Take a look at an old-fashioned incandescent light bulb. Notice how the light emitted has a warm orange/red/yellow color to it. These are the red, infrared, and violet wavelengths being expressed. Now, look at an LED or CFL. Notice how that light looks blue and white, and it's almost irritatingly bright - this is the blue wavelength predominantly expressed.Your genes have been exposed to sunlight for millions of years. And to blue light for less than thirty years. Your genes have not adapted to this modern, artificial light. And because of it, your mitochondria are suffering. This is how something seemingly as benign as the lights in your house could actually be adding to your fatigue.Shedding some light on your mitochondriaYour mitochondria are your body's power plants. These tiny structures, found within nearly every cell in your body, produce a substance called ATP (adenosine triphosphate). And ATP is the energy that powers your body.Those with chronic fatigue syndrome and/or myalgic encephalomyelitis have a reduced functioning of their mitochondria. This results in a net energy deficit. (5) In order to increase your energy and overcome fatigue, you need to optimize your mitochondrial function.And the lighting you use in your environment is the perfect place to start.Just like you, your mitochondria have evolved over millions of years to utilize the energy of the sun. They have not adapted to utilizing the blue wavelengths found in modern daylight sources.One study showed that after only six hours of exposure to blue light, mitochondria were not able to produce energy as efficiently. As exposure time increased beyond six hours, mitochondrial function continued to decline. (6) It is hypothesized that exposure to blue light increases cellular aging and age-related illness. This occurs because blue light is thought to damage the DNA of your mitochondria.Suffice it to say that if you're dealing with fatigue, you need to minimize your exposure to blue light. But what do you use for lighting then?How to avoid blue lightIf you have chronic fatigue syndrome, the very first thing you need to do is ensure your home (and hopefully your office) are free from LEDs and CFLs. Replace these bulbs with incandescents. The small amount of money you save on your energy bill using CFLs or LEDs is not worth the cost to your mitochondria.If you work in an office where you don't have control of the lighting, you're going to need to be extra vigilant. To combat blue light exposure, you need to increase your exposure to red light sources. Your best bet will be getting outside every chance you get.Take your coffee break outdoors. Go for a walk at lunch. Look out a well-lit window. Try to get outside when the sun is at its zenith in the midday. Stay outside for at least fifteen minutes, ensuring you have as much skin exposed to the sun as comfortable.What do you do if you live at a latitude that results in very cold temperatures for half the year? Or, if you live in an area constantly covered by clouds?You're going to need to utilize technology to increase your red light exposure. In the morning, expose your body to an ultraviolet sun lamp. I recommend spending 10-15 minutes each morning during the winter months in front of it. While working in your office, invest in some red LEDs. These will ensure your mitochondria get exposed to the red wavelength during the day. This simple act will improve your mitochondrial function and in turn increase your energy levels.While the type of light is indeed very important, the time in which your body gets exposed to light is equally important.AM light and PM lightDo you hit the snooze button 10 times each morning?This morning fatigue is often caused by a suppression in your cortisol awakening response (CAR). The cortisol awakening response is a surge in your cortisol levels shortly after waking. It is this surge in cortisol that should energize you to get out of bed in the morning.In order to trigger a healthy CAR, you need to get exposed to sunlight immediately after waking. If you live at a latitude that results in a sunrise well after your alarm, you need to invest in a full spectrum UV light. Turn your UV light on immediately after your alarm goes off. This will mimic a sunrise ensuring your body has a healthy cortisol awakening response. This is why so many people notice an increase in fatigue during the winter months - a lack of sunlight exposure.As the day progresses into night, you're going to want to decrease your body's exposure to blue light. Blue light is the wavelength that signals to your body that it's daytime. It's this wavelength that suppresses melatonin production. Remember, you need your body to produce melatonin in order to easily fall asleep.In the evening, ensure your electronic devices (cell phone, computer, television, etc.) have their blue light filter enabled. This blocks the blue light frequency from screens which ensures your body is still able to produce melatonin before bed. There are apps like f.lux that you can install on your devices to ensure blue light is blocked when the sun starts to set. Most cell phones come equipped with blue-light blockers in their operating system.Devices aside, as you approach bedtime, you are going to want to decrease your body's exposure to all light sources. Your skin is the largest organ in your body. And it is full of light receptors. Even if your eyes are not exposed to light, your skin will be. Dim all your lights two hours before bed. And be absolutely certain that your body is not being exposed to any sources of blue light.Make your bedroom as dark as a cave. It should be so dark that you struggle to see your hand in front of your face. Blackout blinds are a must (especially in the summer months). Ensuring your bedroom is this dark will allow your body to produce enough melatonin to keep you asleep all night long. Restful sleep is absolutely essential for anyone working towards overcoming fatigue.One last trick that can improve your sleep is to purchase (and use) orange-lensed glasses in the evening. These glasses block the blue wavelength from entering your eyes. Doing this will help increase your body's melatonin production. Resulting in a more restful sleep.Ok, now you know just how important the right type of light exposure is in overcoming fatigue. Do not underestimate the importance of this. It is so important that I include it in my eBook - seven small steps you can take to overcome fatigue today.Now it's time for me to hear from you!How has changing your lighting changed your fatigue?Want to know more than your doctor about how to overcome fatigue and increase your body's energy reserves?

Gateway Desktop LED Lights Up, but Computer Doesn't Turn On?
the same thing happened to my gateway too! i took it back to best buy and they said it had something to do with the motherboard...but since i bought it still in warranty they replaced it with another crappy gateway since it seems to have a motherboard issue as well1. How to power LED lights without using an outlet?Yes, you can use a battery. Details would depend on the number of LEDs, their specifications, and how long you expect the battery to last. repeat, need more details. There are many ways to hook them up depending on the battery size, and LED specs. In general, you need a resistor of the right value, in series with each LED or set of LEDs in series to set the current. .2. Is a bridge rectifier needed to power LED lights from a DC Power Source such as a cordless tool battery?Basic circuit for powering a single LED from a batterysimulate this circuit - Schematic created using CircuitLabBUT, 'LED light' might mean any complex arrangement of multiple LED elements power supplies current limiters and so on3. What's the law for red led lights? I got red ones and it says they go under my hood above my headlights?You are not permitted to display red lights to the front. Unless it is on a registered emergency vehicle4. I want to buy a used lexus but with led lights, what year?If you mean HID headlights. I would recommend an IS300 (2001-2005) They are really affordable and the of the highest quality for your buck. Lexus/Toyota is rock solid reliability and I know of so many that have painlessly exceeding 300,000 miles and still running like new. The is300 is a compact 4 door sedan with luxury and performance suitable for most needs. The parts are relatively cheap and aftermarket options are endless. Size of vehicle relative to BMW IS = 3 series GS = 5 series LS = 7 series I like smaller, personal compact sedans but if you are going to be carrying other passengers really often I would suggest a GS300.5. Will leaving the 12V socket into the cigarette lighter socket drain battery? even if led lights are off?If the automobile is off, and the light on the charger cable is off, it surely does now not drain the battery at all. There are some cars where the accessory plug is are living even with the vehicle off, but if the sunshine is going off while you turn off the vehicle, it's not on, and if it is not on, it cannot drain the battery by any means6. Why do those small LED lights break so easy and what can you do to fix them?The base of the LED lights contains an electronic circuit to convert the AC voltage to the proper DC voltage to run the LED lamps. These circuits are called an "electronic ballast." These bulbs were not designed to be shock-proof, so there is probably a broken circuit connection in the base, or in the wires leading up to the LED lamp, itself. It is not cost-effective to try and repair them, but they *are* probably repairable by someone who knows how. (I would personally try to fix one of mine, if they were to break.) .7. Is it possible to change the color of the led lights that backlight the keys on the razer lycosa keyboard?You probably could, but would not be worth the trouble. The colour cannot be changed without replacing them. What colour did you want? =) The term "non-adjustable LED's" I think refers to the colour and brightness not being adjustable. Keyboards these days have SMD LED's (surface-mount) that are tiny, and require you to posess surface-mount soldering experience! I do not think even an electronics engineer would want to waste his time replacing all the LED's. Sorry.8. Where can I find individual LED lights?This Site Might Help You. RE: Where can I find individual LED lights? I can not find just Individual led lights. Im wanting them for a project, Ive looked online but I can only find strips and not just "one" to where i can buy them in bulk in different colors. I know radio shack carries them but Im trying to avoid them since they are high priced.
Where Do They Put the LED Lights to Make Rims Glow?

I found some that run off two C cell batteries and do several flash patterns. I do not know what the price was, ( $5 ?).2. Are 5000k LED lights bad for your eyes?Led not good in general for the eyes3. is it bad to keep the LED lights that are under my fish tank on for long periods of time ?I am not sure if it's bad or not, but I know it promotes algae growth, and I also know that fish PREFER darkness when they sleep. I actually did an experiment on it, where I left the lights on in a room and I had two tanks connected to eachother, and one was completely blacked out with paper, no light came in, and one was completely lit with a lamp and everything. During the day, they would chill in the lighted side, and every night, NO FAIL, they would swim to the blacked out side of the tank. Crazy, but true.4. What fuse controls led lights around the linkage gear lever?Remove the gear cover, locate the light. Light is out, change it5. No boot, no beep codes. MB LED lights up and fans come on.?!!! you dont have to have a video card to get a beep post. Check the seating of the ram sticks if not then you either have a bad motherboard or processor. You have to switch either of them to figure out which one it is. Hell it could be both. Just take out the processor and put it back in(try to see if there is a burn smell while you taken it out) and reboot if nothing then you probably have a bad motherboard. See if you can put your processor in another motherboard to see if the processor has gone bad6. help can i do this to my led lights?Hi, Yes you can, you could add another fuse and cable to that existing line using a suitable crimp connector. I might also add that you have put your question in the computer section... not really the place for this question.8-(( Arnak7. What is the electricity situation in Zambia? Do people use LED Lights? cellphones instd of wired phones?About 19 percent of households in the country had access to electricity. More households in urban areas, 49.3 percent had access to electricity than those households in rural areas, 3.2 percent. Among the provinces, Lusaka recorded the largest proportion of households with access to electricity (51.4 percent), followed by Copperbelt (43.9 percent), Southern (13.5 percent), and Central (11.9 percent). The province with the lowest proportion of households with access to electricity was Western Province (3.5 percent) A modern house in rural Zambia has no electricity. Instead it uses paraffin and candles for lights, a car battery to power a record player and small batteries to run a radio/cassette player. It is perfectly possible to manage without electricity. As Zambia is a country with plenty of sunshine, solar panels can be used to generate electricity. So, I cannot see them wanting to be bothered with a huge bicycle and waste energy by pedalling when the sun can do the work with a small gadget.8. Why don't my led lights work correctly on my motorcycle?You need a load equalizer. There is very little resistance in LED's. providing everything else is hooked up correctly9.

Are There LED Lightbulbs Which Could Substitute for an 750 W Bulb?
LED bulb only available to fit ordinary lamp socket and its power limits to 75W. It size is big and never able to fit projector small lamp base1. can I keep my easter lily bulb indoors?I do not know of anyone, other than a greenhouse, that has done it successfully. Go to a grocery store and buy any type of produce that comes in those little plastic baskets. Here, they are grape tomatoes. Put the bulb in the ground, 3X as deep as it is tall, place the little basket over it, upside down, and cover everything with dirt. The lily will be safe.2. Is the lighting in the Nano Cube Dx 24g enough to sustain coral?When keeping LPS or SPS corals and anemones id always say go with the halides. I have the bio cube 29 gallon with the compact PC's and i only keep soft coral in the tank. I particularly like the aquapods with the HQI lighting and would make a much better buy for the extra $100 As far as all inclusive marine setups i feel the aquapod HQI's are the way to go if you want a nano reef with stony coral. I know they make a 150watt and 75watt hqi aquapod. Obviosly more wattage is better. In my expierence keeping stony coral is that normally the tanks that you get them from in the store are under metal halides so moving them to your home with compact PC's shocks the corals and have a lot harder time acclimating to your lighting. With metal halides it wont be much more of an issue. If you think about it the extra $100 for the metal halide aquapod is a good deal because finding just a fixture with ballast and bulb will always cost more than $100. Replacement bulbs alone will be around $80 for metal halides where they are like $40 for the VHO replacements. You will also have to replace trhe bulbs once a year. So yes its more expensive now and in the future for the halide setup but you really save money if you ever plan to upgrade to metal halides later cause you will ned to get the bulb fixture and ballast which will cost way more than $100. To answer your question simply..... yes it is worth it if you want to keep stony corals and anemones. Addition: for soft corals the VHO lights will be fine however anemones may do much better under the halides so i wouldnt reccomend an anemone with the VHO lights. Only soft coral like mushrooms leathers, zoanthids, xenia, ect. will be ok under the VHO bulbs. However those corals will still looks much better and be healthier under metal halides but you can have sucess with them under the VHO's3. what type of bulb to use for growing plants....?HID or "Cool" Fluorescents for early growth. (blue spectrum) High pressure sodium or "Warm" Fluorescents for flowering. (red spectrum) HID and HPS setups will cost quite a bit more, and are harder to cool, but they are worth it in the long run... Use the Fl's for now to start out though. Be careful...4. Science project: Hooking up these substances to a light bulb...?I never did anything that exciting in school. I think you need to combine those items to make that happen. The graphite should work as a conductor5. Singer 2259 machine bulb exploded - What has caused this?Too hot? Without the bulb it could cause a potential fire6. If you remove a light bulb from a multi-bulb lamp, does it put more strain on the remaining bulbs?Its like asking would turning out the garage light put strain on the kitchen lights? answer no7. How to determine which bulb will be the brightest in the series and parallel connection?When the book says:What it is referring to is the power rating of the bulb. This power rating assumes the bulb has a potential difference across it of 120 V (in North America at least - maybe 220 V in India). So, if you compare a bulb rated at 60 watts and a bulb rated at 100 watts the 100 watt bulb will have a lower resistance and draw more current when they are connected in parallel (they way they are designed to used). If, on the other hand, you connect the bulbs in series, then what is constant is the current not the voltage. The bulb with the highest power rating, which has the lowest resistance, will thus have the smaller voltage drop across it and thus will dissipate the smaller amount of power

Often times when a new accessory is added to a car it is just enough extra work to push an already weak battery over the edge, My other Idea would be if one of the wires to your lights or battery is maybe touching something which would ground it out and drain your battery, this is probably more likely because once a car is started they will usually run even if the battery is not working properly. The fact that the car started and then died indicates to me that power is being sucked from the vehicles electrical system, which is why the RPM's went down, the spark plugs did not have enough juice to fire like usual. I would give every wire associated with the new install a good look over, Search for exposed areas, cracks, crossed wires, etc.. etc.. As far as the water running out that will have nothing to do with this but you should get that looked up very soon as that is a quick way to destroy your engine. hope this helps
Save Electricity Bill by Switching to LED Lights
Without any doubt, lights are the important things for a human to survive in the world. Are you worried about the electricity bill? If yes, then there is the smart solution which reduces the usage of electricity thereby consuming less power. In the past decade, the popularity and the usage of LED lights become high. This is not only used for lighting but also used to decorate the homes, office space and gardens. LED light housing is the best option to decorate the pace beautifully. In this post, you may find the reasons why you should go with LED lights.Energy efficientWhen we consider the normal bulbs it consumes only 50 to 60% electricity for lighting and the remaining is converted into energy. Where in case of Light Emitting Diode it uses more than 80% electricity for lighting remaining as energy. It is common that the brightness of the light will become dull after few months. But it is not true in term of LED lights.Conventional forms of lights produce heat and release Ultra Violet radiations. LED bulbs are environment-friendly and the UV radiation produced by the light is almost equal to zero. LED high bay Housing helpful to decorate your house. There are no filaments used in LED lights and it can last up to ten times longer than standard lights.The color options available in LED lights are more compared to traditional lights. The government also highly recommends LED lights for the efficient use of power. You may find most of the Street lights are LED.Most of the people have the common question that is the LED lights fix for all types of fixtures? The LED lights are designed to fit into various types of fixtures. So you don't want to worry about the fixtures. Nowadays lights are available in various shapes and designs this enables the customer to decorate their home and brighten their homes.Applications areasLED lights not only recommended for residential areas this also recommended to use in the commercial places and public places. This lights also used in car lights. You can protect the light from various climate factors like rain, winter with the help of LED Streetlight housing service offered by the best LED housing manufacturers in India. The compact size and faster switching are the additional advantages of LED lights·RELATED QUESTIONI didn't get Google Glass Explorer Edition.

Are LED Lights Eco-Friendly?
Light-emitting diodes are an eco-friendly lighting choice. LEDs are an energy-efficient alternative to traditional incandescent light bulbs, which waste 90 percent of the energy they consume on heat. Other energy-efficient lighting options include halogen incandescent bulbs and compact fluorescent lamps. All incandescent and fluorescent lights produce light that flows in all directions, wasting light as well as heat.LEDs are a rapidly advancing technology that uses energy more efficiently and can save energy in indirect ways, such as with air-conditioning costs (see References 1). LEDs use small, powerful sources of light that illuminate when electrons move through semiconductor materials. They shine in only one direction, produce a small fraction of the heat of fluorescent and incandescent lights, and lasting longer than other types of lighting.Energy Star, a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy, labels LED lights that meet its energy-efficiency guidelines. Although LED lighting design creates efficiencies, poorly designed LED lights do not meet the potential of the technology. Energy Star guidelines require that LEDs consume at least 75 percent less energy than incandescent bulbs and last 15 times longer. In addition, the bulb must turn on instantly.LED low energy-usage saves money in utility bills. As of 2011, an Energy Star-qualified LED bulb has an average operating cost of $1 per year. That compares to annual costs of $1.20 for an Energy Star-qualified compact fluorescent bulb, $3.50 for a halogen incandescent bulb and $4.80 for a traditional incandescent bulb. In addition, an Energy Star-qualified LED bulb's longer life -- ranging from a minimum of 15 times longer than a traditional incandescent bulb to a maximum of 25 times longer -- means there is much lower turnover of bulbs in your house. (See References 2 and 3) Technological advances with LEDs raise hopes for significantly reducing electricity usage in the United States. LED lighting could cut the electricity demand in the country by 1/3, according to the U.S. Department of Energy. The estimated savings from that adoption would total $265 billion, including preventing the construction of 40 new power plants.

What size of battery should I hook up to a 120VAC mini red neon/LED light?There is a resistor in series with the light. Without removing the resistor, you have to have a voltage of 120 volts to make the light work The AA battery is 1.5 volts. There are power adaptors that will supply 120 volts AC from a 12 volt battery. These are normally used with car batteries.6. LED light temperature why does it matter?You can change the temp of the lights individually so that you can have different lighting on a shot.The white balance will enable you to set your baseline lighting/colour profile and then you can hit the shot with different light temps to change the look of it (higher temp = bluer light, lower temp = orange light) - it's a similar principle to using different types of light/bulb.So you light, set your WB for a neutral look, then change the lighting temps to alter the look/feel of the scene.7.

My 4gb kingston data traveler did not show in my computer and device manager. The led is not light up. Help !?If you have other then windows XP .. u may need install the drivers try it with other machine if still there is problem ... u may need to replace the pan drive10. I have 2 led light strips is it possible to buy a blinker that i can wire to them?I think you will get pulled over a lot of you leave them blinking all time. Most blinker devices expect a higher current load than the LEDs will provide. You would need to do the math and buy some power resistors at radio shack. Or find a blinker that does not change speed with the load.11. Is there a LED light available that is equivalent to a 65 watt indoor flood bulb?You could probably make one, but it would be quite expensive, and you would probably need to combine several types to get a satisfactory color balance. Start at the reference for some ideas, then search the web
Can Anybody Explain to Me How I Could Instal Interior Underglow(led Lights) to My Car W/o the Cigare
Just run wires straight from the battery for positive and negative1. doesn't ohm's law applied to every thing? [closed]Ohm's law specifically deals with the relationship between direct voltage, current and linear resistance in the form V = IR. For AC circuits it can be generalised to V =IZ where Z is a complex impedance.Transformers convert an alternating primary current into an alternating magnetic field in the core which is then converted back to an alternating voltage in the secondary coil - This effect was demonstrated by Michael Faraday. (Google Faraday, transformer) He showed that the input and output voltages where connected by the turns ratio. For a 100% efficient transformer we get:We must also apply the conservation of energy rule - you can not get more out than you put in. Given that there will always be a loss of energy (heat, noise etc.) the power output will always be less than the power input. always greater Iin * Vin > Iout * Vout (Power in is always greater than power out)If a load is connected to the secondary coil a current will flow. The transformer will react by increasing the primary current in line with the transformer turns ratio in order to maintain the power in to power out relationship.A filament bulb works by heating the filament to a high temperature. Most of the energy used is radiated as heat rather than light, making this type of bulb inefficient. The colour of the light is determined by temperature. (Google black body radiation, Stefan-Boltzmann law).'Energy saver' bulbs use a gas discharge lamp and phosphor coatings to produce light. (Google - Electric discharge in gases) The current passing through the reduced pressure gas excites electrons directly which then jump from one energy band to another before decaying and emitting a photon. (Google - Planck-Einstein relationship) This means that they generate light energy directly without the need to generate lots of heat energy. This makes them more energy efficient that filament bulbs for the same power input. Hence the term 'energy saver.'LED lights (Google band gap, LED) use a similar principle (electrons jumping from one level to another) through a PN junction in a semiconductor.This is more efficient than gas discharge lamps giving LED lighting more lumens (light output) per watt.2. Sleep Peacefully at Night: How CCTV Keeps Businesses Safe in the DarkNight vision cameras were once the standard for the military, scary movies, ghost hunting, and those energetic wildlife enthusiasts. Nowadays, nearly anyone can make use of the technology, especially when protecting business properties. Night vision technology is instrumental when it comes to business security. Several burglaries and attempted break-ins occur at night, and there are many things you can do to improve your business's nighttime security. For example, installing motion-sensitive lighting and night vision CCTV cameras are the most feasible solutions to help you sleep peacefully at night. CCTV keeps businesses safe. Several surveillance cameras are motion-sensitive and can send alerts when movement is detected. You will instantly know if someone is trying to access your facility without your permission. Yet, typical cameras can not see in the dark, so they can not always pick up motion and send you the essential information you need. This is where the night vision comes in. So, how does it work? Infrared, or IR, is the most common type of night vision popular in outdoor security cameras. This kind of technology is brilliant; it can flood an area with light invisible to humans, but the camera's lens has no trouble picking it up. A possible intruder would see complete darkness while the camera would film in near-perfect clarity using the IR light produced. Humans cannot see IR light because it has a longer wavelength and frequency than normal light that's visible to the human eye. Red is the color with the longest wavelengths visible to humans, and infrared means 'below red'. On most infrared cameras, you will see a unique configuration of bulbs being used. Higher power infrared LED lights are positioned around the outside of the camera lens. IR is used for several different filming purposes and is typically used for wildlife filmmaking. This is because the invisible IR light does not bother the animals as they cannot see it. This makes for a very secretive, nocturnal filming opportunity. Another type of night vision filming technology exists. It's not something commonly used in homes, businesses, or even professional security cameras. Image intensification tubes are used in night vision goggles to collect and significantly intensify all available light, including infrared light. This allows the wearer of the goggles to see in low-light situations or even in total darkness. When an area appears to be completely pitch black, it never truly is. There usually is a source of light, even if the human eye finds it difficult to spot. The light entering the goggles is converted into a green tint, making people's eyes shine brightly in the image created, as human eyes are most susceptible to green light. Night vision goggles that employ this technology are most likely used in military and law enforcement operations. Night vision is instrumental in security cameras since it allows the camera to detect motion more adequately, thus picking up movements by an intruder with ease and alerting you immediately. Although, there can be occasions where you (or the police) cannot get to the location in time, and the intruder makes a getaway. If this happens, your night vision cameras become even more valuable. The clarity of the footage that they can record with IR light and night vision technology means that perps can be more easily identified and arrested. The footage then becomes very useful as evidence. In contrast, a standard surveillance camera would pick up a blurry image in poor lighting or absolutely nothing at all in the pitch dark. Most night vision CCTV cameras also come with extra features and functions to further enhance the footage's quality and clarity. These include: Capture Faces, Number Plates, Etc. With This Technology With this new technology, you can capture faces, license plates, and many other details to provide to the authorities. A lot of activity takes place under cover of darkness, and night vision cameras can help you keep a sharp eye on what is going on. This is very useful in legal cases, investigative matters, or just to provide everyday proof of suspicion.3. Why paintball marker is better?1. They are all under 2 lbs. You would never be able to tell the difference, though. 2. Egos are technically more air efficient but efficiency among high ends nowadays is such a dead topic because they are ALL more efficient than anyone could possibly care. 3. Better settings? Like ease of settings? Because they all have the same tourney modes. Egos are probably easier because they have an LCD screen instead of LED lights. 4. They are all easy to maintain but Egos are a little faster in the maintenance dept (less o-rings to lube). 5. I prefer spool valve guns over poppits, so i like the DM's more. Never shot an NT but i can not imagine it feeling too much different than a DM.
LED Light Bulbs: What to Look For
When you're shopping for an LED light bulb, it's important to find one that provides the amount of light you need, as well as the color of light you like. You'll also want to consider how the light emits from the bulb, and the dimension of the bulb and base. The bulbs in this review are comparable to a 60-watt incandescent bulb.FeaturesA standard 60-watt incandescent bulb puts off about 800 lumens. The more lumens, the brighter the light is. LED light bulbs provide many lumens for few watts compared to incandescent bulbs. Since this is the case, it's better to find a bulb that has low wattage but high lumens because it will save you on your energy bill.You also want to find an LED light bulb that offers a long lifespan. Most offer between 25,000 and 50,000 hours of light. When you look at a Lighting Facts label on the light bulbs, they typically list the lifespan in years. This is based on a standard of using the light for three hours per day each day of the year.When you're looking for an LED light bulb, another thing to consider is the color of the light. Depending on where the light bulb lands on the color temperature spectrum, lights can be all colors: red, yellow, green, blue and shades of white. The shades of white range from warm to cool white. The lower the color temperature, the more yellow your white light will appear. If the light is higher on the color temperature scale, it will appear to cast a cool, bluish hue. Another aspect of the color is the color rendering index (CRI). The higher the CRI number, the greater the number of objects lit by the light bulb that will appear natural.The bulb should also be UL listed and comply with part 15 of the FCC as a Class B device, meaning it won't interfere with radio frequencies. It's also an added bonus if the light bulb is Energy Star Qualified.DesignThe dimensions and weight of LED bulbs are not the same as a standard incandescent bulb. LED light bulbs are on average a quarter of an inch taller. The average diameter of these LED lights is similar to that of incandescent bulbs but varies depending on the model. LED lights are also heavier than incandescent bulbs, so you'll want to be sure that your light fixture can support the extra weight.Most LED light bulbs can't be fully enclosed in a light fixture because heat decreases the life of the light bulb. If you plan to use your LED light bulbs outside, you'll first want to verify that they can withstand damp outdoor conditions. If you want to dim your lights with an LED light bulb, you'll need to have one that the manufacturer has specifically designed to perform as a dimmer.The beam spread is another thing to consider. While incandescent lights put off light in all directions, LED lighting typically sends its light in one direction. The best LED light bulbs that are comparable to 60-watt incandescent bulbs distribute the light around the bulb as well as from the top.Help & SupportChances are you won't need to be in contact much with the manufacturer to use your light bulbs. However, having a practical return policy and warranty are importance since these light bulbs cost more than incandescent and CFLs. A good LED light bulb should come with at least a three- to five-year warranty.LED lighting presents a new, more environmentally friendly option. It's long lasting and can save you money over an extended period. These lights are heavier than other lighting options, and the bulb is on average a little taller than a standard light bulb; however, the base can fit in standard light sockets. These lights will keep going long after incandescent and CFLs would have stopped working, and they'll save you money on your electrical bill.At TopTenREVIEWS We Do the Research So You Don't Have To.more info you can visit: htm.·RELATED QUESTIONI didn't get Google Glass Explorer Edition.
