Here is a Precision thermal photocontrol. This PC has a 1/2 inch cadmium sulfide eye and a built in MOV surge arrester. This was purchased on 1000bulbs.com at the same time as the TORK PC I ordered.
Lol. This one is thermal too. But they do both look very similar to the Touch And Glows. They may be made in the same factory the Touch And Glows are made in, in China.
yeah. these are hard plastic? They seem to have some sort of coating painted on the plastic (almost like a lacquer) to probably protect from dry rotting.
