    I can tell you from personal experience that if you buy CFL's from Home depot, and they burn out, just call the number on the bulb. If it's within the guarantee period, or close enough to count for shelf time, they ship you brand new bulbs. You then take the dead ones to Home Depot, and they take them back to properly dispose of them.

    Would you mind complaining for me since you're already doing it for yourself?


    Thanks.

    I'm curious.

    How are the manufacturers of LED lights dealing with the 60 and or 120 cycle flicker issue? (like you see in LED Christmas lights.) Do they convert to DC and filter with a capacitor or just use a capacitor?


    I like the idea of LED lights, but if they flicker like the Christmas lights do, it would drive me nuts.


    On that note, anyone have a cheap and easy way to get rid of the flicker on Christmas light?

    @yet_another_user: I have LED lights and they don't flicker. The Christmas lights flicker because they are cheap and the supporting electronics is minimal.


    The D part of LED is diode which only conducts electricity in one direction so, for best effect you power them with DC. I would guess that the cheap Christmas light controllers drop the voltage from 120V AC to whatever the LED can handle then convert the AC into DC but don't smooth out the DC to get rid of the 120 Hz ripple.

    @daqman:
    Or they run in an AC series, which divides the total voltage by the total number of bulbs. So 10x 12v bulbs in a series can simply be plugged into an AC outlet running 120v, and they'll get along just fine. Until one of them burns out, and then things get ugly...assuming you don't catch it right away.

    And here I end up bandaging my hand after the fact because the fscking bulb has tattooed my palm with its wattage rating when I try to change it.

    Why would you continue to try to chop after the lights went out?


    You need the SlapChop if you are wanting to do that.

    I don't understand how it can only use 7W and put out so much heat. Or do the LEDs use 7W and the circuitry another 25?

    @gdigital: That's what I thought. How can anyone call this efficient energy when most of it is dissipated through heat?

    If incandescent bulbs don't need heatsinks, why would this? As far as I know, LEDs run much cooler than traditional bulbs. Or is this some big honkin' LED that gets crazy hot? It's hard to figure scale from the pic but it looks like your typical household light fixture size.

    @fsusmithc2: High power LED's, like Luxeons, generate a fair amount of heat, and it affects the light the bulb puts out. The reason Mag-lites were so long in adding LED's is that the parts that hold the bulb/direct the light are plastic, and don't allow the heat to dissipate very well. Most of your high powered Luxeon LED lights are aluminum mostly to vent the heat.
