Hi . I'm making some changes with my tortoise lighting system as I think his current clamp lamps aren't safe. So he has an uv tube for uvb light and two previously mentioned heat lamps. One is a spot lamp and the other one is a regular household bulb. I plan to build an light arm, just a L shape screwed into his enclousure. Picture is attached. And buy a farm refclector (20 cm wide). Will this be ok? Picture is attached . Please tell me what you think.
