Has anyone put a florescent light in a safe to stop moisture, and if so how did it work out? Or is a goldenrod the way to go.
Any info would be appreciated.
I know this doesn't answer your question about the lights but it is related ....
I put a couple of Hydrosorbent Dehumdifer bricks in mine & I've never had a problem. I'm in Florida and it is pretty damp down here most of the time.
The "bricks" are 450 grams of Silica Gel each & is supposed to protect 33 square feet each. They can also be regenerated by warming them up in the oven. I got them at Bass Pro Shop if I remember correctly. Sounds funny but they're great. I have never had a problem with any corrosion or rust & it like a rain forest down here in the summer sometimes.
Just thought I throw that out there.
I use the goldenrod and silica gel canister, just to be sure. The goldenrod is better than a light bulb for several reasons, it is cheaper to operate and it is designed to circulate warm air in your safe.
