Sounds like a good arrangement.

The bulb is powered by a timer, which cycles it on and off in half hour cycles. The primary purpose is to create a heat chimney effect under the shroud, which has a small opening at the top. Warm air rises through the shroud and create a circulation, together this keeps the mount dry. Understand it is inside an observatory as well, with the roof closed.
On night's when I am using a scope, I just leave the scope mounted and throw an old blanket over the whole setup. Inside the observatory it does not get damp and i take it off the next morning.
