building new vivarium, questions on LED lighting

So I recently put my leo in a 29 gallon and I am just disappointed with it. A 29 gallon is 18" tall and with the ecoearth, the hides, and the fake plants, there's about 17" of wasted space (I'm exaggerating to paint the picture). So on Google SketchUp I've designed some stackable enclosures that are 30x18x12 WxLxH so she'll have a lot more ground space to play around in.

My questions: I current have a 350ma moonlight LED driver purchased from RapidLED which puts out enough juice to power 3-4 LEDs. These LEDs are gorgeous and I absolutely love the effect they put out. I have 3 cool white LEDs, but I'm only using 1 because all 3 is about as bright as the Sun and it's a little ridiculous. The more I google, the more confused I get. One thing I read says "leos don't need light, they're nocturnal, but they do need night/day cycle" another thing says "lights too bright and your gecko will never come out" and some that just plain say "leos don't need light don't waste your time"

Now I understand they need day/night cycle, and I feel my cool white LEDs are probably too bright because she NEVER comes out when it's on so my question is, what if I switched to what they call "photo red" LED? It's a deep red somewhere around 670nm on the light wavelength so it's just barely visible to the human eye. Another thing I've read conflicting stories on is leos can and cannot see red light. Would this photo red LED that's barely visible to the human eye be just as bright as the cool white LED? Obviously whichever path I take, they will be on a 14/10 and 12/12 timer, with NO lights at all during night time. The lights are simply so I can see her and to give her that day/night cycle.

tl;dr - Can I use 670nm photo red LEDs as a daylight for my leo? Is cool white LEDs too bright?

Leos are crepuscular (active during dawn and dusk). It's been proven that they can see red light. You won't need any lights unless there's not enough natural light from a window :)

You will want to avoid any lighting which is not within the range, that is color temperature of natural daylight, so the red is out.

I have used LED's for Leo's in the past, prior to swapping to UVB systems and while the Geckos hide away during the day, this was no different to their natural behavior patterns and is not indicative that the lights are harmful, rather the opposite in fact.

It is true that much of the information out there is conflicting, and even here on what is an excellent forum, you will find a range of opinions on this subject, some more informed than others, but all equally well meaning.

The reality however, is this, the best thing we can do as forward thinking keepers, is strive to simulate as much of the Geckos natural environment as possible, in this case providing a suitable photo-period via white LED sounds like an excellent idea to me, but you must ensure the Gecko does have suitable choice of refuge in order to sleep away the daylight hours undisturbed, just as it would in the wild.

As a point of information, how useful this will be may vary, but bringing the color temp to around 8k Kelvin is where you want to aim when simulating sunlight. How many LED's you use will have to be at your discretion, as you mentioned, you dont want to bleach the entire enclosure in blinding light !

Thank you so much, Shane. Very useful information. I'll avoid the red LEDs. My love for LEDs is due to their flexibility with installation. You can pretty much hide them from sight entirely, especially in the plywood enclosure I am planning to build.

Here is my 29 gallon currently:

I use a low wattage LED, doesn't give off enough heat to change temperature gradient and it's about 150 lumens. I have this on a timer. Our natural light is shotty because we have insulated certain that are thick so it takes the sun out of the picture. I know the Leo's will come out (especially since on a timer) but even during the day. I built a 30x18x18 and used the extra space to give climbing ledges (mostly because my Leo lives to climb and be up high.20170525_061239.jpg
