You know how some rooms are wired so that certain electrical outlets are on the same circuit as the light switch? So you can plug a lamp into them and when you turn on the light switch the lamp goes on.
I don’t have that. But I have a regular light (attached to light switch) and some lamps that I want to control with the same switch, for convenience. I figure there must be an automatic switch of some sort that I can plug the lamp into (like a light-timer, but not) that will sense when the big light is turned on with a photosensitive circuit, and then turn the current to my lamps on.
Anybody know if such a device exists and where I can get it?
