Do crested geckos need a photoperiod?

[Paleosinensis]

I have a shallow closet that I am considering putting my crested geckos in since space where I live is rather limited. The temperature is a stable 74-76 and on an interior wall. Do crested geckos need a photo period? Do I need to leave the closet door open except for special circumstances so they can receive natural sun cycles? Or are dim warm-white LEDs on a timer enough? I am aware they do not require UV, this is really more about their circadian rhythm.

As you said, they don't require UV, but I feel it is always good to let them receive natural light. Also, will the closet allow air flow and the tank to dry out over night after a misting? Don't want stale, humid air handing around, that is how animals get sick. Lots to think about really. I personally wouldn't put on in a closet. You got a photo of it?

I would leave to closet doors open as much as possible for air flow. The air will get stagnant in a small closed space, will likely remain too humid, stinky and just not be a healthy environment. They should have somewhat of a day/night cycle but it doesn't have to be bright light. I kept my crested geckos in a pretty dark room for years, but a small amount of light did get in around the heavy curtains I used to keep out the heat (and also some ambient light from other rooms). It was enough to regulate their day/night cycles even though it was never anywhere close to full daylight in the room. My collection is now in a different location, in a room that does receive full sunlight as heat is not so much of an issue. I find that their behavior and activity is pretty similar to the when they were in the darker room.
