Nice your setup looks perfect. Sometimes all the clutter in the tank is better for the gecko as they feel more secure in their environment. I would assume dim lights are fine just like the moon is in the wild. You can do some more research on uvb lighting and get one for your tank. You can set the lights on a timer so that your gecko maintains a good light cycle. But it’s ok without a light too. Drawers really aren’t a good idea. Good luck with you and your gecko!
