Agreed, I don't know how you do anything with a room that cool. If 50* is what the temperature is, you can't move to a warmer room, and you can't increase the temps in the room, I wouldn't even attempt keeping reptiles in there. Even with a PVC enclosure, MAYBE you could get into the 70s with a heating element running 24/7 but as Bogertophis said, one flick of the power, one bulb burning out, any short time spent without that element on, and you have a sick or dead snake.
