Reply to comment by EliminateTimeZones in How many of these recessed lights can I use on a dimmer switch? by notscammed

Those are not rheostat (resistor) based though. They use thyristors to chop the electrical current (you can hear them humming if you listen closely).

Basically they are switches that turn on and off very quickly.

Nope. Definitely a thing. Also I'm corroborating your claims that they are too big to fit in a standard electrical box.

I just pulled mine out of basement storage and took a look. Inside is a variable auto transformer. Lookup "Luxtrol WBD" on eBay to get an idea.

Nope no thyristors in these. Just checked. Just a variable autotransformer. (Not a resistor or rheostat).
