DIY 72 LED build

[toolmanbmw]

These are the LEDs I will be using. 36 royal blue, 18 10k white, 18 6.5k white.


LEDs layout,18 LEDs per heatsink.


The ballast that I will be using. Blue on one and white on the other. 12 LEDs per string and 3 strings per ballast. That should give me around 620ma per LED.

Questions, comments, and suggestions are welcome.

you might want to reconsider your white-blue ratio, I originally went with a 50/50 ratio but found it to be too white, I now run 24 wh and 48 blue which gives me about 20,000K. I also run blue and royal blue. IMO.

I use these same emitters in 50/50 ratio and I dim back the whites to about 80% and I like the result. If I was to change mine I would substitute some reds instead of the white.

On my setup, I have 8 x 10w blues at full power and the 20 combined 10000k, 6500k & 20000k are barely on for a 15-20000k blueish look which we prefer.

For those used to metal halides, the intensity of LEDs will be a big surprise and how dim you'll have to set your lights to NOT light shock your corals will make you think the tank is dim.
