C. Crane is selling an 800 lumen LED light bulb, that uses 8 watts of power and lasts for 30,000 hours. $120. Out of stock until mid-May. 800 lumens is equivalent to a 55 watt light bulb. That's 100 lumens per watt, and 250 hours per dollar. Still quite a bit more expensive than compact fluorescents, which get 1600 lumens (95 watt incandescent) from 23 watts (70 lumens per watt) and glow for 12,000 hours for $4.75 (2526 hours per dollar). I predict that the end of the compact fluorescent is nigh. Long live the LED!
