Heating and lighting essentials
Maintaining the correct thermal gradient is vital. The basking spot, created by an overhead heat lamp, should be 38–42°C (100–107°F). The cool end of the enclosure should remain at 22–25°C (71–77°F). At night, allow temperatures to drop naturally to around 15°C (59°F) with all lights off. Install a 10% or 12% linear UVB T5 bulb overlapping the basking zone and remember to replace UVB bulbs every 12 months, as their invisible rays degrade over time, even if the light still appears to be working.
