Facts about the need of light for crested geckos
There is not specific number of about how much light this species need. But compred to other geckos or reptile, crested geckos do not need special light equipments.

Which light equipments are good for crested geckos?
Incandescent bulbs might emit a lot of heat inside a small and confined space. Even CFL bulbs can generate heat, so be sure to monitor temperatures when using lights so as not to endanger your geckos.
Sunlight might not be desirable due to heat buildup. Glass also filters out the beneficial UVB rays present in natural sunlight, so it is an ineffective source of Vitamin D3, an important nutrient generated by sun exposure or from a supplemented diet.
There are specialty bulbs made either for night-time heating or for night viewing. These could be red (often labeled as infrared) bulbs, or blue spectrum (moonlight) bulbs to be kept on all night long.
Crested geckos may be able to see these wavelengths of light, and it may interrupt their normal nocturnal behaviors. Be that as it may, you may use these these special bulbs for brief periods in the evenings/early morning to heat the tank or to provide you with some visibility for nighttime viewing.
