Well, I'm not sure about the AP fixtures, but I ordered a 4x2 from RBI and bought two 18" florescent fixtures to install inside for viewing: one day and one night. I got my 18" blacklight bulbs from WalMart. They're just regular florescent blacklights, and I already have one over my Amel corn cage. Makes it look really freaky in there

If those aren't good for reptiles, PLEASE let me know...I couldn't find anything on the subject in searches...
