Contrary to popular myth, reptiles can see red light. For nocturnal reptiles, it's unnecessary because they can see just fine in the dark, and for diurnal reptiles it can negatively affect the quality of their sleep. Providing light at night may also disrupt your reptile's circadian rhythm.
If you need a nighttime heat source due to nighttime temps too cold for your reptile's needs, we recommend purchasing the Exo Terra Ceramic Heater as an alternative.
