UTH questions.

Now for some reason I was under the impression that I couldn't keep a bulb on all the time. How else would I created ambient heat?

You certainly could keep a bulb on all of the time. Usually the bulbs you do this with aren't light bulbs - they're typically ceramic heat emitters (CHEs). You could keep a light bulb on all of the time, but since BPs don't really need light, there's not much of a point in it.
