Unlike most LED bulbs on the market that bundles a few dozen LEDs together to produce a gentle glow, this new LED bulb uses three pieces of High Power High Output 1W LED emitter that produce as much light as 120~150 normal LEDs combined. It's highly efficient too. At its peak efficiency, it produces over 60 lumens per watt, which is about 10X more efficient as incandescent bulbs and 2~3x more efficient than a compact fluorescent bulb! This is the ultimate power saving light bulb! It also lasts over 50,000 hours. If you keep it on 8 hours a day, 365 days a year, it won't burn out in 17 years! Compared to a 40W incandescent bulb it's designed to replace, it will save you a total of $222 in electricity cost(12 cents per KWH) over it's entire life, and save 2479 pounds of carbon dioxide emissions(1.34lb per KWH). This LED bulb produces a cool white color similar to cool white fluorescent tubes.
