My leopard gecko has a heat mat. Does it still need a heat lamp?

Thanks for reaching out about Sushi. Adding a heat lamp to bring the temperature the rest of the way up is recommended. This should be put on a rheostat so the temperature can be fine tuned. Good luck.

Thanks for reaching out about Dwight. Do you know how cold it is getting at night? If dropping below 70, probably needs a red heat lamp or ceramic heater, neither of which should affect his diurnal cycle. Good luck.

It is okay for nighttime temps to drop a bit. Make sure they don't go lower than the low 70s F. Consider a thermometer at each end of the enclosure to verify temperatures. If necessary, a 60 watt CHE would probably heat or maintain temps above the low 70s F in a small tank overnight. You would need to test it out. Save the receipt in case you need to return it or buy a 100 watt CHE and move it farther away from the tank.

Thanks for reaching out about Darwin. Leopard geckos like warm temperatures, the hot spot should be around 90-95 F. But ultraviolet radiation should also be provided even though these animals are not very active during the day. Good luck.

First i would recommend describing exactly what type of heating system you are using at the moment. this following link might help you: https://blog.onlinegeckos.com/leopard-gecko-heating-temperature-requirement-under-tank-heating-pad-belly-heat-how-to-install-uth-thermostat/

The tank looks fine, but geckos absorb heat better through their bellies than through their back, as they tend to be more active at dawn and dusk, rather than other lizards that are active during the day and would bask in the sun in the wild.

You can use this bulb but it will do nothing but provide light, which is fine, if only for a few days to a week at most. As a side note, all UVA/UVB lights should be changed every 6 months regardless of whether or not they are still "working". The light will no longer be producing UVA/UVB after 6 months.
