The UTH will provide the basking temperature of 90 degrees, so all you need is an infrared heat bulb on a lamp dimmer to keep the air temperature around 80 degrees.

The UTH must be regulated by a thermostat. here are 2 good ones. (don't waste your money on the crap sold in pet stores)

The hydrofarm, these are cheap and will do the job but lack accuracy and safety features. these should be replaced with a better thermostat when possible.

The herpstat is a great permeant thermostat. they cost more but are extremely accurate and have multiple built in safety features.
