GeoBulb (TM)

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 Add comment Edit post Add post

New info on GeoBulb

The bulb above is the GeoBulb II. At ccrane.com, that bulb's price is now down to $49.95. With its 30,000 hour life, it's now same price as CFL (but uses less electricty than CFL and has no mercury). GeoBulb III will soon be available. It's 30% brighter (355-570 lumens), lasts 66% longer (50,000 hours), uses 6% less electricty (7 watts). However, as it's now the cutting-edge, it's still pricy ($86-$100).

I ordered one

Thank you, Brian! I ordered one. Should have it in a week or a little more (UPS ground from CA to NY). Will give a report after I've tried it out.

I ordered the 60 watt equivalent Geobulb II. They say they'll have the Geobulb III in stock on 10/21/2009.
