Do Crested Geckos Need A Heat Lamp?

Crested geckos, otherwise known as Rhacodactylus ciliatus, are a type of lizards indigenous to New Caledonia, an archipelago situated in the southwestern Pacific Ocean.

Unlike most lizards, crested geckos do not need a heat lamp in order to thrive, as their body is naturally adapted to regulating body temperature. As a matter of fact, you could argue that excessive heat can harm their health.

Why Do Crested Geckos Not Need a Heat Lamp?

– They are nocturnal and accustomed to temperatures ranging from 65 to 75°F
– They do not bask as other lizards do
– They can regulate their body temperature on their own

What’s the Optimal Environment?

Crested geckos thrive in the following conditions:

  • Humidity of 50% to 80% year-round
  • Temperatures that range between 65 and 80°F at night
  • A hiding spot and a perch that provide small areas of basking during the day (less than 80°F)

To create such an environment, you can use a quality substrate, live or faux plants, and a nocturnal red LED heat lamp to simulate a night-time glow.


Crested geckos do not need a heat lamp to be happy, healthy and thrive in captivity. However, it is important to make sure that temperatures do not exceed 80°F in your crested gecko’s enclosure.
