Interesting acrylic canopy. Isn't there moisture/condensation gathering in the plexiglass? I would think the humidity would short circuit your CFL bulbs?
Are your CFL's rated @ 3500K or 6500K?
Why didn't you peel off the protective film off the acrylic? Once that flim gets wet, it's not going to be easy to remove.
Bulbs rated for 3500k, I just left the plastic film on to block some light but I might just spray it black or white. The plastic film is easy to remove even when wet, paper on other hand it has to be a new piece of acrylic and it won't matter an old piece and your gonna be there for a bit peelin.
