LED Lights on Incandescent Dimmer

Ok, my friend recently changed some hi hats in the kitchen to the new halo LED retrofits. He didn't change his dimmer. He has an old incandescent dimmer. It dims but not a lot. The dimmer is on/off with a slide. I told him that he is damaging the new LED retrofits by not putting in a LED dimmer.

Am I wrong or should he change it. I am going to print your responses if he is wrong.

Only the LED bulb manufacturer can tell you for sure, you should be asking them or browsing their web site for that info. I doubt you will damage the LED at all since the dimmer can only send 0 to 120 volts to the bulbs, it can't generate it's own power and shoot 250 volts thru the bulb, but it might not dim the bulbs as dim or smooth as a dimmer made to use on LED's.

I'd start by looking up the mfr's web site for that bulb and reading what it says about dimmers, call or email customer support if necessary.

First of all check the package of that LED bulb to see if that is a dimmable verison or not.

If you got a dimmable verison then it should mention about which type of dimmer it can be used. It will be stated on the package and also check with the LED manufacter for more info some case they will have a listing what dimmer is approved with that type of LED bulb.

Ditto with the dimmer switch itself.

The answer will be based on NEC ( National Electrical code ) or CEC ( Cananda Electrical code ) or ECF ( Electrique Code France )
