It would be lovely if these lighted mirrors had a circle light inside that I could use for shooting videos. That is not the case though. It's just two 20 watt bulbs behind some extra foil on the back of the glass.
The dimmer switch only controls one of the two bulbs.
The magnifying side of the mirror wasn't broken so I put a wire between the screw holes on the frame and hung it on the wall in my lab with some LED string lights behind it. Now if I get something in my eye I can see to get it out!
I'm saving the cord, lightbulbs, and dimmer. I'll just throw these in my bin of lamp making supplies in case I ever need them for a project. NOW I can throw the rest away.
