He stated that this is a new behaviour since they got a new hide for it, so unless they changed the lighting with it, the chances that that's the cause are very slim. And just because your lack of overhead light works well (which I have no doubt that it does, for the record), that doesn't mean an overhead light doesn't work. I use a light as my primary heat source, and my gecko doesn't seem bothered at all. She's out during the day sometimes (even often prefers to be closer to the edge of her hide than all the way back in) and is "perfectly healthy and happy." Of course, with albinos, that has to be reconsidered, as they get in more light than regular leos. But, imo, a light is closer to their natural habitat than only a bit of ambient light through a few windows.I assume you have an UTH and the light isn't a source of heat, just light? If so, I'd just leave it off for the time you're gone or (as others have said) buy a timer.
I'm not sure I would suggest keeping a bright over tank light on much anyhow. Just keep a lamp in the room on - it will stress the gecko less. Yours might be hiding so much because there's too much light and it bothers him. My geckos live in my back bedroom - it has a few windows that let a moderate amount of light in but they don't have a light source other than that (unless I'm in the room with them) and they seem to be perfectly healthy and happy.
Have you acquired data comparing how bright the inside of the tank is compared to outdoor light? From what I can see, it doesn't appear very different - unless, of course, the gecko looks directly at the light. But looking at the light inside the tank, it - to my eyes - looks very similar to the light outside, hence my suggestion that is closer to their natural habitat than very low light. But it would be interesting to see people do some actual analysis on it. I'll have to do that when I get a camera.I believe direct, bright light, as would be put out by the majority of over tank lights or aquarium hoods is not ideal for geckos -- especially albinos which are light sensitive morphs - hence my advice.
I read that the behavior started with the new hide. Since I don't know what said hide looks like or what the hide before it looked like, I'm trying to help consider all the possibilities. For example - if the old hide was small or not light-proof the gecko may have felt just as uncomfortable in it as out in bright light and had no preference. The new hide one could provide a much more secure and/or comfortable hiding place that the gecko is taking advantage of now. I don't know if this is the case or not - but provided my advice on the light as I don't think the light is ideal in any situation and can cause the gecko a lot of unnecessary stress (and discomfort if it is a morph with light sensitive eyes).

That seems unlikely, but I suppose theoretically possible. Temps are monitored with a digital probe and kept in the low 90's. And I'm not saying she spends much time out of her hides, but it does happen - as opposed to what the OP described, where they don't see their leo ever, which the other person attributed to the use of a light.That behavior that you are describing kind of sounds like the gecko is coming out during the day or staying toward the front of its hide to get near the light to warm up. I can't say for sure but it seems that way from what you describe.
Over 30+ years in captivity, using a UTH has proven to be the best way to heat a leopard geckos enclosure. I am not saying its the only way because several people use lights alone, a CHE, or one of the two in combination with a UTH and seem to have success, but I feel that a properly sized and regulated UTH is the best way.

P.S. I never said the use of the light was causing anything. I said IMO it was not ideal and I would not suggest using it.
