Thanks George
The external fan was a thought but since I don't expose for very long and a good time between exposures, I think I might try the switch idea. Just one more thing to remember but habits of turning on and off are do-able. I could make a time delay circuit to turn off , say for a few seconds before exposure, and then trip the lamp to turn on. Then it would reset and turn the fan back on.
Just thinking here.
