I use these:

It doesn't matter that they produce very little light, it's the filament heat that you want. These produce good heat output without being so hot that they can overheat items nearby.
You can get lower watt ones as well, I just find these 25W ones best for keeping my mount head dry in its convection shroud.
I use a 24hr timer to turn it on and off when the observatory is not being used, like now. So the timer will turn the bulb on at nightfall and off after sun up. You can use staggered on/off periods as well, like on for 30min and off 30 or 45min, then on again. Whatever works best for your convection device.
