DIY LED for SPS (ecotech radion cluster)

[ankitgandre]

Hello friends,
I m planing to build a DIY LED Cluster for SPS tank. Need huge suggestions on the lighting/colors/leds/wattage.

Details about my tank:

Dimensions: 3ft x 1.5ft x 1.5ft i.e 49 Gallons
Skimmer: Reef Octopus NWB 110


Targeting this LED only for SPS tank.
Below is the design i have planned for :

LED Specs :

LED: Bridgelux led 3W each
Total : 81 Watts

Royal Blue - 11
Blue - 4
Warm White - 2
Red - 1
Green -1
White - 8

I will make 3 panels like this so total will be 243 Watts.


Please help. :bigeyes:

three of those would certainly be plenty. 2 would be fine as well. what kind of drivers will you use? optics?

 

[ankitgandre]

3 watt 700mA drivers. 2 guess will be less for SPS tank. about optics i m still confused.

 

[rwb500]

well at only 700 mA you would probably want 3. will they be dimmable? how many channels?

I like to run with no optics to help prevent shading but this requires more LED power. Usually 60-80 degree optics are a good balance of efficiency and spread.

ok i ll try both aid n aid-out optics.

so according to u 3 will be sufficient for a SPS tank?

I'd look into building two, but with more channels, so you can run the emitters closer to their rated output. It'll also give you on-the-fly control of the color balance, in case you're not happy with it as-built.
