Lighting and Temperature
Leopard geckos are a nocturnal species so no form of UV lighting is necessary. A simple spotlight with the appropriate wattage bulb can provide both daytime light and heat. Daytime temperatures should be around 90 and the nighttime temps can go down in the low 70s. When I say 90 degrees I mean this should be the temperature directly under the spotlight. This will allow the rest of the cage to remain from anywhere to the 80's to room temperature. I feel that it's best to provide any reptile with a temperature gradient and let them regulate their temperature. I have problems with undertank heating pads and hot rocks as they don't raise the ambient air temperature in the tank and their surfaces often produce extremely high temperatures.
