outdoor lighting

Hi guys, I'll be using a UV blacklight in my cemetery, and I'm wondering how I can best shield it from any possible rain. Or is this the kind of thing that you simply shouldn't use if the weather is bad? Thanks!

I'd love to change our outdoor lighting to red or orange this year...but I can't seem to find a budget friendly way to do it. We have those malibu uplights illuminating our palm trees and landscaping, and I can't find red bulbs...plus the lights are expensive. Anyone know of a fire-proof way...
