Use whatever wattage bulb will attain a 90F to 96F basking spot. Usually an 80 or 100 watt bulb on a dimmer switch, easily purchased at most home improvement stores, will get the desired results. Be sure he cannot come into contact with the bulb as this can result is serious burns or injury. No nighttime lighting is required. A 12-14 hour light cycle is recommended.
