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 (only 7 watts). However, as it’s now the cutting-edge, it’s still pricy ($86 – $100).

I ordered a GeoBulb on 3/26/2008 and it just arrived today. When I first turned it on I was expecting the “60 watt equivalent” first advertised, but now I see the rating has been revised down from 800 lumens to ~300 for soft white. It looks like a great bulb, but not for $120. I’d rather get 2 EarthLED CL-5s or other offerings from TheLEDLight for the same money.

Hate to break it to everyone but the GeoBulb is dead on arrival, my pre-order was cancelled at this site: http://www.computergear.com/c-crane-geo-bulb-led-light-bulb-60w-warm-white.html

and they told me it is never coming out. I’ve heard of vaporware but vaporlightbulbs? I’ve ordered a zetalux from http://www.earthled.com, we’ll see how that works out.

Why does the manufacturers website say this bulb (which looks really cool) only puts out 381 lumens?

It’s almost November. Has anyone actually seen a GeoBulb work? Is C-Crane or any other supplier actually delivering them?

Here is a new technology that seems to be able to compete with (or beats according to its maker) LED tech.

My understanding is that the AC to DC transformer generates heat and wastes power and adds costs. It would be nice if the bulbs and the transformers were separated and a standard DC socket was developed! (don’t get me started on DC power losses its off topic and not relevant. You can do conversion at the socket or down the hall, its up to you with DC sockets.)

One should also factor in peak Copper (already reached) into all these matters as well. Interesting is that LEDs don’t have copper leads on them…

LEDs produce heat; esp the bright ones. They do NOT handle power spikes or heat as well and need protection.

How about “green” molded plastic for these things? are they green?

It’s a little tricky comparing all these LED bulbs fairly because each manufacturer has its own understanding of what a standard incandescent bulb produces in terms of lumens.
Starting with the watts/lumens table from the following web site, I decided to compare the numerous LED bulbs mentioned on the metaefficent web site:
http://en.wikipedia.org/wiki/Incandescent_light_bulb

Here’s what I got:
Geobulb 800 lumens at 8 Watts ($120) (55 Watt incandescent; 14 Watt CFL equivalent) ( http://www.ccrane.com/lights/led-light-bulbs/geobulb-led-light-bulb.aspx )
EarthLed’s Evolux 900 lumens at 13 Watts ($80) (60 Watt Incandescent; 15 Watt CFL equivalent) ( http://www.earthled.com/evolux-led-light-bulb.html )
EcoLED 315 lumens at 7 Watts ($80) (32 Watt incandescent; 8 Watt CFL equivalent) ( http://www.betterlifegoods.com/ProductDetails.asp?ProductCode=LED%2DCAT21416 )
LED PAR-20 500 lumens at 9 Watts ($50) (40 Watt incandescent; 10 Watt CFL equivalent) ( http://www.ledwaves.com/product.php?productid=19636&cat=413&page=1 )

This would seem to make the Geobulb the most efficient at 100 lumens per Watt (but also the most expensive).

Feel free to correct or add to this analysis.
