if you can mix 2 part expoxy, and glue chips down, and watch some you tube videos on how to solder, and also watch youtube video's on tuning meanwell drivers.....

then you can build your own.... i built my own fixture 8 months ago... and let me tell ya, that was the best thing i ever did, i have amazing colour, and amazing growth..... and my hydro bill went down 40 dollars per month!!!

I looked at Rapid LEDs website. Yep, I can do that! And use the heatsink from my existing unit once it stops being Shaivo. May that day not come anytime soon.
I was hoping the site gave better advice.. I can do basic electrical stuff, but... What colors, what angle lenses, how many and what power do I need to light a 60 mixed cube?

Does anyone know a good tutorial written in "for the inexperienced" language? I want my SPS and LPS to thrive, but not burn my nps. I imagine that might be quite a spectrum tweak, or not possible a all.

Dang, I need another tank. Anyone have a spare 125 gallon tall?

There is a basic formula for how many leds:
Length of tank X Width, then divide by 16 if you keep sps, and 20 if you keep lps.....

for example.....
my tank,
72 X 18
1296 / 16 = 81
1296 / 20 = 64

i used 96, for maximum coverage,(i just dim them down to 90 percent) and its an even number (each of my drivers can handle 24) , As for lenses, a Naked LED has a 120 degree lense on it, realisticly if your tank is less than 24 inches deep, you dont need lenses, the light still reaches the bottom, but i do run 60 degree lenses on the front row, keep the light off the glass a bit, and i have some coral on the sand bed.....

As for ratio, I used 60 white to 40 blue, it is pretty close to 14 k, when both are turned up, it i was to change anything, i would do 45 white, 45 blue, and 6 UV , i seen other builds since min with the uv, and they look amazing....
