So, I'm trying to regulate the temperature on the hot side of the tank, but the thermostat I tried first sucks and doesn't do squat (zoo med 500-R reptitemp). I am trying to regulate a 100 watt red heat bulb, but all the main thermostats seem to only work with UTH. Is there a thermostat out there that any of you use for heat lamps, keep in mind, I only have 1 lamp and 1 snake, so I don't need the top of the line high wattage ones.

The lamp is on a dimmer switch so the days that I am home all day, I can keep the temps perfect. But if I leave for any amount of time and the room temp shifts, then the tank either gets cooler than I like or too hot on that side. I'm looking for something reliable that will increase and decrease the temps as needed without me having to constantly adjust it.

The other side of the tank is a constant 82-85 no matter what (it has a 60 watt blue heat bulb)
