Some of the bulbs I have purchased only lasted two weeks at no more than a couple hours use per day. Very disappointing (maybe 30 hours lifespan). I am a big fan of LED lighting. Choose a bulb that fits the application (lumens and color) and you will be happy. Unfortunately many manufacturers and vendors overstate (I'm being kind here) their products specifications. I have purchased 45 LED bulbs and have had mixed reliability. The good news - some are very reliable. I have five LED bulbs outside that have run dusk to dawn for two years with no problems. The bad news - some bulbs are VERY unreliable. VERY high failure rates. I purchased 12 of one type LED bulb and 12 out of 12 have failed (8.5W product 47856 from LEDLight.com). 100% failure rate. To make matters worse they are refusing to replace them now. Beware of LEDLight.com. This company is selling products that they know are defective. No support for failed LED bulbs. These bulbs are very expensive ($20 - $105) and in some cases last only two or three weeks. They refuse to replace defective bulbs. LEDLight.com is selling known defective products and has bad customer service. ledlight.com, LED, problem, fail, failure, burnout, quit, reliability, unreliable, review LED bulb reliability – HIGH FAILURE RATES

Although the price is still a bit higher, I believe there will be a price drop this year. I have just ordered several LEDs from Giftsmax.com and I’ve found that the quality is better than I expected.

At prices like that I think the planet is doomed. Get a grip. Yes, great, but at $100 for a single fitting XR-10 I think somebody is missing the point.

I think that if GreenLED's numbers are correct, the 400 lumen bulb that they sell for $50 would be nearly enough to replace a 60 watt bulb. You have to take into account a few other things however, like the fact that the LEDs themselves are VERY directional and so far are only a suitable replacement in a spotlight/can light/reading light situation. They are terrible in a shaded lamp or an old fashioned lamp style porch light (pointed up, the bulb is going to shoot light right through the top of the shade and almost no light to the sides).

I have recently replaced my undercabinet lighting with Cree based LEDS from Insaini LEDs. I used the warm white version (yellowish like incandescent). The quality of the light is excellent. However, the light output was significantly lower than the halogens that I replaced. I overcame this issue by repositioning the lights and using twice as many lights. The result was a more uniform lighting on the countertops. Of course this added significantly to the cost. In the end, I replaced 80W of halogens with 14W of LED and I am happy with the result. Note that this is an application where CFL was not an option. As a result of this experience, I am a firm believer in the quality of Cree LEDs. But we need to be skeptical about the quantity of light output. Thanks John C. Briggs The Cree LED lights are excellent.
