Unless you mist the area heavily, probably not. I have my shoplight
fixture on open, coated steel wire shelves, and have surrounded three sides
of the shelves with plastic drop cloths, mostly to keep from soaking the
wall when I do mist. After several years, no rust.

Subject: Light fixture and humidity!

Hello everyone!

I`m planning to get fluorescent fixture ( 4 feet long ) to put over my
shelving unit. Also, I would like to cover the shelving unit with plastic to
increase the humidity level.
Question: Should I be concern about humidity and electric fixture and rust?
I will add some fan to create an air movement but I `m concern about the
possibility of rusting ?

Thanks

Claude
