Right now the warm end of the tanks (for those that aren't brumating of course) is about 82F and cool end temp. is around 75F. At night it drops down to about 65F. I use just regular old heat lamps on them and they go off at night. During the warmer months, I put the warm end up to aournd 85-90F and cool end is usually in the mid to upper 70F. All of them are on thermostats, so it's easy to regulate the temps., as long as the room doesn't get too hot (sometimes in the summer, from the high temps. and the heat from all the fluorescent lights, it can go into the mid 90s!...but they seem ok, as long as they can cool down again at night).
