I have those on a good portion of the night in all the bedroom "nightlight" tanks. The fish are fine, No algea, plants are all fine too. Actually in one of my bigger tanks with the two crayfish I've found that when I want them to come out in the day I just turn the blue moonlights on and they come out ready to interact thinking it's night as long as the sun isn't shinning in the room too much. My kids do it all the time to "play" with the crays.

I think there were only like 8 LEDs on my fixture. 32 sounds like it would be a lot.

It does sound like a lot but they are two 24 inch strips and are end to end covering 48 inches. They are made to put under a car to produce a blue glow so it's not an intense light they have a diffuser to spread the light evenly I would post a pic but can't figure out how

If it works it works A pic is not going to depict what the lighting actually looks like - you are the only one that will really know how bright it is.

Overkill depending on your tank size. Only my 75 runs that many blue LEDs and that light is an absolutely absurd light all around 62 of the blues and it's really rediculous when I put that on at night. The 48(or 46 can't remember lol) there are 6 which is good and all the nightlight tanks which run 4-6g have 3.

Edit.. just turned the switch and it leaves only ~36 on for the night setting. Still bright a hell.

I know the high setting is really bright but you still can't even see the fish just kind of a silhouette

Like Jaysee said a pic will not really show how bright it can be but here is mine..middle of a very sunny day with 36 blue leds. I only leave this one on the moonlight setting when I have friends over or for whatever every once in a while because I do worry the brightness of that will effect the fish. I would half that if I were you. But you already have it set up? Maybe it'll be fine. One way to find out.

My caution would be not to leave any "lights" on for at least a few hours at night, maybe 6 or so, so the fish (and plants if you have therm) have the period of complete darkness which they do need for their physiology. You might find more data in my article on light and its effect on fish:
Lighting: How It Affects Freshwater Fish

Byron Hosking, BMus, MA

The aquarist is one who must learn the ways of the biologist, the chemist, and the veterinarian. [unknown source]

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
