It was one of those basic Honeywell ones... I'll see if I can find it...
Here we go, something like this. Dunno if it was the same model, but same brand and design. It still turns on and I can hear the motor working, but the blades don't move. It might just need too be cleaned out, I don't know. I've always just assumed it was the humidity since I can't imagine a motor with all those coiled up wires and such taking 80% humidity very well, LOL.
It's too bad about it being a used room. Mine is a spare bedroom, the only purpose of which is to house plants. Makes it much easier. I've learned really quick that a cool, humid room is really refreshing, everything smells and feels fresh and clean. A hot, humid room is freaking miserable. LOL.
EDIT: One thing I should mention about the lights in the enclosed space with high humidity: no safety concerns, or at least none that I ran into, but the fixtures and the rack itself did end up rusting a little bit. I guess that's sort of inevitable, though.
