Ok heres the question. I have been reading that moonlight is 1 lux or lower. Does anyone know what spectrum this light is I.E. more red or blue? broad or specific? Also how can I know what light my pets actually prefer? Right now for heat I use a full spectrum 'day glow' bulb 50w in the day, evening time I switch to 50w red bulb and at night I use a 75w moonlight bulb. Its a higher wattage because the shape of the bulb is not triangular so it does not "direct" light well.

My temperatures are fine.. but I have the lagging feeling like the moonlight bulb and the red light are both too bright and affect the activity level of my whites treefrogs. I mean the way I think is this... They are nocturnal so the majority of the time they are alive and moving and conscious is at night. If they have no light thats like sentancing them to blindness! So I want them to be as comfortable as possible. Right now at night time I lay a few magazines and a white t-shirt over my screen top so the "moonlight" is very dilute.

I know they have ceramic heat emitters but that would be way way way little ambient light. I guess what I wanna know is are there any articles that describe nocturnal lighting in a clear direct serious way for amphibians???
thank you much

I haven't heard of any. Many of the "nighttime" lighting setups are for us humans' benefit (i.e. so we can see our animals moving around even when it's "dark"). You could probably get by with a human-style night light plugged into an outlet across the room and the animals would be OK if all you can make out is dark blobs moving around in the enclosure that's about right! ) Too bright (bright enough for us to comfortably observe them) and you make it look like a full moon night (or brighter), which will actually LIMIT some species' natural behavior/activity as they tend to not move around as much on full-moon nights out of fear of being more easily seen by predators.

Now you have me thinking about my banded geckos maybe I need something similar for them but I'll have to check the ambient room lighting at night to see how bright/dark it is.

How about using a white LED as 'moon'? It can run on a small mains adaptor and can be dimmed with a simple potentiometer. I even think the warm white types would give a spectrum quite close to real moonlight.

My guess on the spectrum is that it is close to that of the sun, but a bit more yellow because the moon has a slightly yellowish color. The light is, after all, just reflected sunlight.

LED might be good never thought of that. I think the ambient lighting in the room at night (I leave on the computer/monitor and there's diffused moonlight coming through the window) is probably sufficient. This may warrant further study.
