My apartment in central Jersey (where I am on the weekdays) has too few lights in general, and half of them are lamps. So, to get full light, I still need to go over to the lamp, which is low on a desk, reach under the lamp shade, and turn it on.
Many apartments are like this, where they expect the
tenant to use lamps. It's inconvenient.
Kind of annoying
So, I figure, why not a plug with a switch or just some kind of switch where it turns ON the circuit/plug/appliance when it SENSES light, and OFF when the light lowers. This way, the one already installed wall light switch will turn on all the lights in the apartment, and also off.
There might need to be controls so you can calibrate it first to light levels. And of course there will be issues with dimming. And of course, the way the thing works is first it senses light, then it turns on the circuit while ignoring the photocell for like 10 seconds, then goes back into sensing mode.
So the wall switch will finally conveniently control all the lights and lamps
