I did that for other stuff I wanted dry/warm, started with a dead 33 CuFt freezer - originally had a 60W bulb (porcelain "outhouse" socket in the bottom) - bulb kept it too warm and burned out a couple times a year, so I changed it to a 100 watt rough service bulb (say what??!?)
Oh yeah, I also fed the 100W bulb with one of the HF "speed controls", turned down so the bulb was a dull glow - it gets turned off in summer, temp stays around 80 degrees in winter. The door seal keeps everything totally dust free; originally the drain hole in the bottom had a little "mushroom" over the hole, I replaced that with a grommet for the wire and drilled a hole in the very TOP of the box, inserted the "mushroom" there for a small vent.
Results - all my (smaller) spendy stuff stays perfect, bulb hasn't burned out in about 10 YEARS after the speed control addition. Takes up a fair amount of room, if you want smaller check CL for a dead "dorm" frig (and with that size, one of these would be enough)
First pic below shows the bulb at the bottom... Steve
Sorry, here's the bulb for the above link...
Yeah, I know it's messy; Amazon STILL hasn't shipped that box of 1000 "tuits"
