You can use a full spectrum basking bulb for heat and light. This is probably fine for smaller cages, but for large enclosures one bulb will not be enough. We recommend you use a non light emitting 24 hour heat source, like an infrared bulb or ceramic heat emitter . Ceramic heat emitters are a little more expensive, but they will last 5-6 times longer than a bulb. There are many thermometers and humidity gauges available to make sure your pet is getting enough heat and humidity.
Most reptiles absorb a lot of vitamins through their skin.
Normal bulbs and windows have properties in the glass that filter out the spectrum they need. We recommend using a vitamin light or a full spectrum bulb inside the cage. Some people prefer using day and night bulbs on timers to best replicate the day and night spectrums. Others use full spectrum lighting. Both methods should prove to be adequate.
