just put a 60w lightbulb in there, but would like to have it on a thermostat so
it isn't running continuously. Probably just be easier to use heat tape.

Yeah, particularly since they're self-limiting whereas the bulb is a
constant drain the heat tape is cheaper in the long run. Plus, being in
contact it is more efficient preventing pipe freeze than trying to heat
the whole volume to maintain the air temperature.
