I have a zoomed tortoise house, and I currently use an 80 mercury vapor bulb for my lighting, any ideas on how I would set one up for my zoomed tortoise house? Can I just put it laying on my railing, or should I try to hang it inside on the walls of the enclosure? The walls are 8.5 inches from the substrate, is that enough height to have a strip wall UVB. If you think that my enclosure can't support a strip light, I'm just gonna get a single deep dome for my mvb instead of the dual heat dome I am currently using for my setup as a dual heat dome combo as it hangs slightly crooked due to the weight of the weight. The single dual deep dome should help with basking on a more concentrated spot compared to the actual deep dome since it will be better to aim for the basking area of my enclosure.
