rock lee Quick Facts
LED light is equiped by LED as light source. Full name of LED is light emitting diode, which have advantages as follows:
1. Energy saving
Efficiency is 80-100lm/w now, which is over 8 times higher than efficiency of incandescent bulbs. Usually, 3W, 5W and 8W LED bulb can replace standard 20W, 40W and 60W incandescent bulbs.
2. Long lifespan
Lifespan of LED is over 30,000 hours. It’s over 20 times longer than lifespan of incandescent bulbs, which is also 5 times longer than fluorescent bulbs. If you have ceiling lights in your room, LED light is a good choice. You do not need to waste of your effort to replace bulbs every year.
3. Eco-friendly
LED does not contain any leads, mercury, argon, xenon or krypton gases. Fluorescent bulb contains mercury.
4. Low voltage
LED work with low voltage. It’s more safe. It’s also perfer partner of solar power.
5. Small size
LED is very small, so it’s very flexible to design various kinds of fixture.
6. Full color choice
LED can emit any color you want. Daylight white, warm white, red, blue, green are all available.

LED Downlights A Greener Choice
Traditional incandescent lighting has dominated our illumination needs for many decades. That technology is now being phased out largely due to rising energy cost. It is being replaced by light emitting diodes (LED) technology. LED downlights are very much part of that trend. They can be used indoors or out in some of the toughest environments. For example, they are used on pleasure and commercial vessels, including exte ally on decks and masts.

More Efficient LED Flashlights Are Taking Over
Flashlights, called torches in British English, have been around for a long time. Hand portable illumination is clearly desirable in many situations. LED flashlights use the latest LED lighting technology to produce a better product in almost every way. The first flashlight was introduced in 1899. It was made possible by the development of portable batteries with paste electrolyte instead of liquid as had been used before. Early flashlights, along with most of them for the next 100 years, used incandescent bulbs.

Favorite Quotes & Thoughts from rock lee
"This bulb has a very nice, warm look to it. The package says 450 Lumens, not 400. Note that the description says that it will replace a 60W DOWNLIGHT. That is pretty much correct, because the light dispersion is mostly in one direction. This would be good for ceiling locations where you don't want much light going up, or in cans. I put this in a difficult-to-access outdoor fixture (not a moist location) and it looks very good. It will be on about 12 hours a day, and I'm looking forward to not changing the bulb for around 8 years. We'll see..."-- DaveH SF
"The Lighting EVER 7 bulb is, in my opinion, as good or better than a standard Edison light bulb. I am using the bulbs in all of my reading lamps and a more powerful model to light my garage. The secret to current LED designs is to put them in overhead lamps with the bulb base facing down. The light from the bulb directs from the top. Overhead lamps and and "in wall" fixtures (with out covers) work very well. If you plan to phase out your CFL's do not get standard lamps with the bulb facing up (unless you want to illuminate your ceiling). Over the past year I have broken two CFL's when I accidentally knocked over a table lamp. In a great twist of irony I purchased an overhead lamp for my LED from Targot. The package included a "free" CFL. The genius who packaged the box put the CFL next to the 10 pound base of the lamp. The CFL was broken and I will have to return it to Targot. They can keep it. My Lighting EVER's will never break and they will possibly last for the rest of my life."
