What do you call a light socket like those ued in construction sites?
They have a white and a black pigtail, about 6", and the socket is surrounded by rubber. I'm using one now, and I can only get an incandescent bulb into it. I need 100 watts so I want to change to CFL but the base of one of those is too big to fit. Before I got to the store, I want to search online.
