By all logic I should've figured that, but for whatever reason I thought there's a "lightless" type of UVB bulb for nighttime (like a CHE). Except not only would that, to my knowledge, be impossible from an optics standpoint, but reptiles aren't under sunlight at all times in the wild either. The dumb things we think up sometimes.
