Yeah, they're supposed to take 120V. Apparently they're susceptible to heat failures - they need a bit of ventilation. If you had it enclosed that may have been the cause.

My lad has them almost throughout his place of abode and yes, ventilation is key.

I'm familier with them and like them, except for the price. I suppose it's a case of you get what you pay for.
LED lights have come into extensive use for the lighting on emergency vehicles. They are expensive, but they show up better than anything else made, and they run with significantly less power draw. Important when you have limited power production and a large draw.
They're also great for flashlights. We now have cheap, tiny flashlights that give out as much, or more light than large, heavy, expensive lights of the past.
I still like the plain old incandescent lights. Cheap and reliable.
I can't stand compact flourescents. They're good at first, then after a while, they kind of dim down.

I bought these LEDs from deal extreme:

E27 7W 4000K 700lm 14-LED Warm White Light Bulb - Purple (AC 85~265V)

http://www.dx.com/p/152093

There might be even better models these days. I wouldn't buy anything less than 100 lumens per watt. Also, 4000K color temp is the one I like best. This model is hemisphere and the purple thingy is a heat sink, so I assume it has a long life span.

85-265V That's some variation for a bulb that should output a regulated amount.

It has "wide range" Switched-mode power supply, but yeah, the white leds operate around constant 5 volts.

Yeah, it was just a simple night stand lamp, open, so ventilation should have been good. I'm going to swap it out with another one, and give it another chance. I'm all about trying to lower our electric bill every month, so i'm always lookin at new ideas.

I like the 3500k - 4000k range, but the GF likes the 2700k ones.

Thanks for the input guys!

Always admirable. We've got CFLs everywhere but I might have to look into these LED bulbs now they're a lot cheaper.
