Geobulb: A LED Light Bulb Replacement
The Geobulb is an 8 watt LED light that replaces a 60 watt incandescent bulb. It generates 800 lumens of light to be exact — either warm white light or cool white. This bulb has a sleeker design than some of the LED lights I’ve seen — check out that aesthetically pleasing heat sink.
The Geobulb lasts 40 times longer than conventional incandescent bulbs and 10 times longer than compact fluorescent. LED bulbs like this have the advantage of being able to be turned off and on quickly, and being able to withstand cold temperatures. It sells for $60 which, for an enthusiast like myself, is a reasonable price for a ultra-efficient light that will last 10 years or more. In fact, over the course of this bulb’s life, it is less expensive than incandescent bulbs or fluorescents.
The GEObulb led light is available from Amazon for $57.

Are they dim-able? all of my non-dimming fixtures already have fluorescent bulbs in them. I have almost a dozen places where i could use good energy efficient and totally dim-able bulbs.
Love the fact that this product elevates LED bulbs to works of art!
Now if only the price could drop by 50-75%, we’d have a lighting revolution on our hands…
FYI, another LED bulb that fits conventional light sockets is the EvoLux from EarthLED. Not as beautiful, but quite a bit more affordable (~$80).
I hope to review the product in a few weeks, but meanwhile here’s a link to the EarthLED site:

Until the price drops for a more affordable residential use, I’ll stick to CFL bulbs.
I heard LED bulbs are better for outdoor use, no?

This bulb replaces a 50W incandescent and is only $49.95. Who says the revolution isn’t here now?
one thing I don’t understand – if LEDs are supposed to be very efficient because they don’t turn the electricity into heat – how come they need a heatsink?
I’m looking forward to using them in my household. It is still expensive to pay for them up front. But predictions say that prices will go down. Something good to look forward to.
LEDs don’t produce infrared so they don’t radiate heat as an incandescent bulb does. They do produce heat, however, (because they aren’t 100% efficient) and that heat has to be radiated away via a heat sink.
That’s my understanding anyway.
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.
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?
Here is a new technology that seems to be able to compete with (or beats according to its maker) LED tech.

It’s almost November. Has anyone actually seen a GeoBulb work? Is C-Crane or any other supplier actually delivering them?
Why does the manufacturers website say this bulb (which looks really cool) only puts out 381 lumens?

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.
Poor geo-bulb, we hardly knew ye…
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.
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).
