Do Crested Geckos Need Lighting?: 1 Minute to Understanding Crested Gecko Lighting Needs

Crested geckos (Correlophus ciliatus) are fascinating reptiles native to the forests of New Caledonia. Many owners wonder whether these nocturnal lizards require special lighting in their enclosures. In their natural habitat, crested geckos spend much of the day hidden among leaves and branches, only becoming active at dusk and throughout the night. This behavior influences their lighting needs in a home terrarium.

Strictly speaking, crested geckos do not require intense UVB lighting in the same way many diurnal reptiles do. However, providing a low-level UVB light can benefit their overall health by supporting vitamin D3 synthesis and calcium metabolism. A standard 5.0 UVB bulb placed on a 12-hour cycle (on during the day, off at night) can help mimic the natural day-night cycle. Otherwise, a regular day-night schedule—using ambient room light or low-intensity LED lighting—is sufficient, as long as the gecko still has a period of darkness each day. At night, avoid any bright lights, as these creatures are adapted to dim environments and can become stressed by excessive illumination.

As an interior designer, I see parallels between creating the right environment for a crested gecko and designing a comfortable living space for people. Lighting shouldn’t just serve a functional purpose; it should enhance well-being and recreate natural rhythms. When setting up a terrarium, pay attention to the way light interacts with the environment—include shaded areas, hiding spots, and gentle transitions that make your gecko feel secure. Achieving a balance of light and shadow makes for both a healthier reptile and a more beautiful enclosure in your home.

Tips 1:

Place artificial plants and branches to create shaded spots and reduce direct light exposure during the day. This not only provides comfort for your gecko but also brings a natural aesthetic to the terrarium, making the setup visually pleasing while supporting your gecko’s well-being.

Q: Do crested geckos like bright lights?

A: No, they prefer dim environments; bright lights can stress them, especially at night.

Q: Should I turn off the lights at night in the terrarium?

A: Yes, mimic nature by turning off lights at night to support their nocturnal activity.
