Led bulb choices need input.

The idea of having the UV with the blue might be nice for night viewing and give a bit of extra pop. I can't say that i think the red in there will be a good look with just blues on(but ya never know).


With the above layout it looks very similar to a unit that we sell like crazy. So your color should be just fine and if you end up getting the reds on the wrong channel, it is pretty easy to switch LEDs around(depending on what brand you are getting).

Good luck

So this is what I'm thinking for the final combination.

Channel 1 is: 12 7500K cool whites, 4 4500k neutral whites, 2 520nm green, 4 480nm blue, 4 420nm violet.

Channel 2 is: 22 450nm royal blues, 4 430-440nm deep blues, 1 660nm deep reds, 2 400nm UV.

Here is the layout I'm thinking.

Messed up last post. It didn't attach the picture.

If it were me I would not have the 480 nm Blues and greens on the same channel as your whites. You are going to want independent control of them.

Also I would go with 4 UV's instead of 2. All of the reading I have done also suggests that UV has a huge role in SPS coloration. I am going to be doubling the UV LED's in my existing build.

What would you channels and combination look like if it was yours?

[Seth81]

Channel 1: Whites: 12 7500K cool whites, 4x4500k neutral whites,
Channel 2: Actinic: 22 x 450nm royal blues, 2 x 430-440nm deep blues, 4 x 420nm violet, 2 x 4 400nm UV.
Channel 3: Accent: 2 x 520nm green, 4 x 480nm blue, 1 x 660nm deep reds (if you insist on having these)

Also What currents are you running these on? I have independent control of my neutral and cool whites, when I shift the light to the warmer side of the spectrum (like what your red LED will do) it honestly makes the tank look like garbage.
