I'm almost finished my new enclosure. I have 3 45watt halogen flood lamps about 8" above the basking spot and one on the other side of the cage. I know there's a huge debate about UVB and I'm frankly ignorant about the different types. I will admit I was using a ReptiGlo Compact Fluorescent 2.0 for almost 2 years and I've started to notice he's getting "blueness" over his eyes and it seems he's having trouble seeing food when I tong feed him. I have since taken the UVB out of the cage and I can see some of the blue going away in his eyes. I'm guessing that some UVB is needed as natural sunlight has it but like I said I'm not educated in the area at all. I know there are long tubes you can get. Would they be better? I am dusting with calcium powder & D3 in it. I understand the UVB is needed to synthesize the D3 unless I'm wrong. Please help clarify!
