This 13 watt bulb, the Evolux by EarthLED, is said to be first LED light to be able to replace a 100 watt incandescent. The lifetime of this bulb is rated at over 50,000 hours — which is five times longer than a compact fluorescent bulb. Other advantages of LED bulbs is their ability to brighten instantly, and be switched off and on rapidly without problems. They also contain no mercury. LED-based bulbs do, however, require more energy to manufacture that CFL or incandescents.
The Evolux uses a CREE light engine, and it contains a small fan to cool the circuit board. EarthLED has a video of the bulb in action, and also some photos showing the type of the light it renders. The Evolux bulb sells about $90 right now. If you are serious about energy efficiency, or if you’re using solar power, this might be the bulb for you.
It’s available from GoGreenSolar for about $80. See also the $60 GEOBulb, which is another LED light bulb.

This is a little pricey right now but as time goes by I’m sure prices will come down on the LED light bulb
It is interesting that this LED light has small fan inside to cool the PCB and LEDs,however,is this fan make noise when it is working? Has long lifespan the same as LEDs? We have developed 12.5W LED light which can also replace the 100W Incandescent,but in lower price.
I love how innovation is always stifled by a fincancial bottom lime. I doubt they’re recouping R&D costs. I’m turning off my CFL and going to bed, wake me up in 1000 years when humanity grows up.
Other LED’s specifically state “DIMMING CIRCUITS MAY DESTROY THIS BULB”.
Most CFL bulbs have mercury which will end up in landfills if not recycled.
LED”s have very long lifetimes.
As long as the warranty is only 1 year, the price will need to drop quite a bit for these to be reasonable.
The cost is $99.
I question their lifespan claims. As near as I can tell they just copy the lifespan claims for smaller LEDs. After having 8 LED nightlights burn out I don’t believe these claims outright.
Like the electronics in a CFL, which needs ventilation for proper cooling I think a 13W LED (or 13W of LEDs) also need proper ventilation for a long service life. And most fixtures won’t provide such ventilation. Most lamps will, but not the torcheries (which is the style we have at home).
And given that it only has a 50% power savings over a 26W CFL and a 1000% price premium, (assuming you can get a $1 CFL, which is common), they don’t seem cost efficient at all. I’d imagine that there are applications where they would be worth the cost, anywhere which is properly ventilated and the cost of replacement (labor costs or accessibility issues) they might be worth it.
On the other hand I’m really happy to finally see something useful being produced and have hopes for better and cheaper LED bulbs in the future. They may well become cost effective in a few years.
How’s the color temperature? My only issue with LEDs so far is that they are very cold blue. If this one is close to 2700K or so, that would make it a first, as far as I know.
I concur with @cephoe that they are probably dimmable; if they are this is (another) big advantage over CFLs. While there are dimmable CFLs, they … suck :-).
Also what’s the retail price? LEDs have been pretty expensive so far — yes they pay back if they really last 5x longer than CFLs (which are like 10x incandescents).
I think this bulb is probably dimmable — not sure though.
What are the stats on the LEDs? where can one buy them? how far are they pushing them? Is the fan really not needed for the LEDs?
Seems to me that there are DC options possible here. I’d rather invest in large copper DC cables and a big DC power brick to power dozens of ‘bulbs’ or led strips than have EACH bulb contain its own power supply and even its own fan!
Is it dimmable? Are any LED bulbs?
Truly wonderful technological achievement!
It would have been even better, if the government (DoD) would have done a direct and maybe, even exclusive large deal with the producer, which would have slashed the price to only 10%.
It could have been about new National Energy Strategy, in which billions of light bulbs certainly play a very important role of lowering power consumption and carbon footprint in the easiest possible way.
…he got awake and immediately realized, that all was just a short dream, because oil simply needs to be bought, especially at the record price of $116 per barrel…to keep the Boss smiling…
