I've got a coupla' these, they are GREAT in front of a lathe or mill in Winter...my elderly JRT used one in the kennel in his last years, and swore by it.

I did run the cord through some old heavy heater hose, to preclude chewing.

If you go with the incandescent bulb,...use a standard NEW 1 gallon paint can, mount the ceramic fixture on the lid, and cut the holes top and bottom sides with an old style "Church Key". For my rabbit nesting boxes, I use a clear "vibration proof" 40 watt chandalier fan bulb,...
