Below is a photo of my set up. I have a question regarding UVB. The light fitting holds a UVB tube and the lamp is for heat. My question is how are the UVB waves emitted? Does my turtle have to be directly underneath the tube? This is because even though I direct the lamp towards the area underneath the UVB tube, Gamera seems to prefer basking a little to the side, that is he isnt directly underneath the fitting. Is he still getting exposure?
