this still confuses me....i have a 24" reptisun 10.0 fluorescent bulb but no fixture, do i have to purchase a zoomed or exoterra hood (or any reptile brand) for it to emit the ubv rays? or will any 30" t8 fluorescent fixture work? like one from home depot? i don't want to spend 50$ plus shipping...i bought the bulb on accident and now want to use it.
