Crested Gecko - Stressed by Light

Hello all. I'm Martyn, this is my first post here. Have recently picked up a crested gecko after wanting one for many years.

I'm a bit concerned that the bulb I have fitted is a little too powerful so wanted some advice.. The crestie is a baby a little over 2 months old and has been in my care for 3 days. Until it is older it's is housed in a small exo terra 30x30x45cm with a compact top light fixture. I'm now starting to think that the komodo 26w 10% UVB bulb that the shop sold me is far too much light for such a small enclosure.

It has generally settled in well and is very active at night, and has at least disturbed the food I've left out. However when the light comes on (timer), rather than find a nice spot to rest for the day, it will take whatever shade is available in its immediate vicinity and not move until the light goes off again in the evening.

There is plenty of shade available and I understand the concept of letting the gecko self regulate, but is it possible that with it being so young and timid, it's too scared to find a better spot.

I suppose I've got a few options and I'd appreciate some advice on which to take.

1) Continue as is. Let the gecko take care of itself. Leave it to learn the day/night cycle.
2) Fit a less powerful bulb, something like the komodo 15w 5%.
3) Leave the light off and just rely on ambient room light until it's settled in better.

Sorry for the longish post! And thanks for any help.
Cheers :2thumb:

I would doubt this.... assuming you have it sat across the mesh screen of the enclosure, even with a reflector around 40-50% of the emitions will be blocked, then what-ever does get through will penetrate only a small depth, leaving plenty of room for cover.

My curiosity would get the better of me though if I was observing behaviors associated with stress/ Appetite drops, dark colors, hiding away a lot in the lower areas and check my temperatures/and UV output with a solar meter from the highest point of the enclosure.

This being said, when I provided my cresties and gargoyles with UV same as yours, I never really seen them basking under it, like ever, seen one or two doing it at work a few times but that was it. I often wondered if it was just a case of them needing time to adapt to it since they never really had access to it prior? honestly I have no idea.

It's worth investigating though for your own mind ease if nothing else.

Well the problem is the gecko isn't going to find the cover. Today it spent the whole time at the top right next to the lamp only partially covered by a couple of leaves. It's almost as if it freezes as soon as the lamp comes on.

I'm not particularly worried about the UVB as I understand 10% is a reasonable amount through mesh. It's more that the light is too bright in such a small enclosure.

I have a good temperature gradient in there ranging from 28c at the top to 20c at the bottom.

Cresties will maintain wild behaviour. That is to rest in partial shade and creep up to bask early in the AM usually. So they rest and power up during the day and then become more active in the evening.

Mine basks in an index of around 2.00-3.00 most days for a few hours and then goes back downwards into the foliage before starting the usual jumping around at about 5pm, an hour before the lighting goes off.

The most important point is that everything must be proven safe and be measured. Only then can you be sure of effective and ethical supply.

Hope this helps.

John.
