is for a basking spot or for the air temp?
air temp should range from (88-90 degrees) on warm side to (70-75 degrees) on cold side
basking temps can range from 95 to 115 degrees
my temps are 88 degrees in the warm side and 72 on the cool side
my basking spot is 112 degrees
i use just a 50 watt basking bulb and a 75 watt infrared bulb
my beardie is 6 inches long and is kept in a 20 long
