Best UVB Tube Fixtures for Reptile Enclosures
A tube fixture spreads UVB along a strip rather than concentrating it in a small spot, which lets the animal move in and out of exposure instead of being stuck with one intensity wherever it basks. That gradient is the point. Fixtures differ in reflector quality, which changes how much light is directed downward, in ballast type, in the tube lengths they accept, and in whether they mount above a mesh top, inside the enclosure, or hang vertically for a tall setup. We weighed reflector design and build, secure mounting hardware, T5 versus T8 compatibility, the range of lengths available, cord routing and heat around the housing, and how easily replacement tubes can be sourced. Shorter fixtures suit standard tanks. Full-length units suit large enclosures where the tube should span most of the gradient. Vertically mountable models suit arboreal setups. Tube strength and distance should follow your species care sheet.
