I think that your BP can stand to go one night with a light on. I know BPs are as breakable as glass, but, I would hate to think one night and a few extra hours of light will break one.
You will be fine, leave the light on for heat tonight. In the morning go pick him up a new heat bulb.
You know, ceramic heat type bulbs in my past experience seem to have a pretty long life and heat pretty well. They also don't put out any light at all. They do although cost more then a bulb. Something to think about maybe.
