Unlike most LED bulbs on the market that bundles a few dozen LEDs together to produce a gentle glow, this new LED bulb uses one single piece of High Power High Output 2W LED emitter that produce as much light as 60~70 normal LEDs combined. It's highly efficient too. At its peak efficiency, it produces over 100 lumens per watt, which is about 10~15X more efficient as incandescent bulbs and 3~4x 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 25W incandescent bulb it's designed to replace, it will save you a total of $138 in electricity cost(12 cents per KWH) and $2.25 in bulb replacing cost(67 cents per incandescent bulb) over it's entire life, and save 1541 pounds of carbon dioxide emissions(1.34lb per KWH). Compared to a 9W fluorescent bulb, it will save you $96 in electricity cost and $10 in bulb replacing cost($3 per 9W fluorescent bulb, average life of 8000 hours). This LED bulb produces a warm white color similar to the warm white light produced by incandescent light bulbs.
