DIY 72 LED build

[toolmanbmw]

Hey guys. Just received my 72 led from aquastyle. Going to build my LED lights for my 75 gallon. Will post more picture as I progress with the build. Enjoy

This is the heat sink where the LEDs are going to be mounted.

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.

Thanks for the input guys. I think I will do what snaz is doing and dim the white. They will be hooked up to the VDM port of the apex. How do you guys like your LEDs?

I love mine, sunrise/sunset simulation, shimmer, good coral growth, low heat and energy efficient, no lamp replacement.

i had 1:1 rb:cw ratio and didnt like it, the 2:1 royal blue to neutral white is waaaay nicer IMO. GL with build

I love my LEDs. I went from 2 x 13W Power Compact lights to LED so I have no comparison to MH. I think anyone in the know would say my tank is too white but I like it. I have seen Seahorse_Fanatic's big tank and it is gorgeous of course but a little too blue for my liking.

Here is a true colour FTS with blue and whites at 100%

BTW. What is the rose/salmon colored coral on the left?
