I'm making an LED lamp and was about to install a feed thru switch, but I noticed my wire is too thick for the switch. Rummaging through my drawer for another, I found an old dimmer, fun.
I see that it has the words "permanently installed incandescent fixtures only" written on it. This dimmer is so old, I'd imagine they didn't consider LED when making the warning.
My main question, is it safe to use this dimmer? The LED uses 7 watts, it's 500 lumens.
