DIY LED layout on a 20" cube???

I think you will find it a bit too white with that ratio of white to blue. What ratio do you have over your Biocube? You should try it without the optics first. They rate them as 80 degree, but I found the beam a bit too tight. Much less shadowing without them.

id recommend using ocean coral white instead of the red and blue emitters. together the OCW looks white to us but fills in a lot of spectrum lacking by the RB/NW combo. keep the RB and NW as close as possible. if you use the OCW, you could do 2 clusters without any color banding.

I've got mine on a dim4 controller and I use that to colour mix. Each spectrum colour is on individual channels and 3 of those RB's are used only for moon lighting. And I am running no optics, although if I remember correctly the UV comes factory with optics pre-mounted.

Thanks for all the responses guys. I've been away from a "real computer", just a dying smart-phone...

My cube is 8 royal blue and 4 Neutral White, (too many LEDs I know!), no optics. both on same dimable driver. It'd be nice to have ability to dim separately, but I'm happy enough with colour. Definitely not too blue, I'd say most would want more blue/higher K. As for the blueness of my next project we'll see?

Good idea to hold off gluing optics, thanks.

Thanks for input, I'm going to hold off on 3ups or OCW and try and use what I have. Can they only be driven to 500mA? I guess you'd need a separate driver too?

Ya, this point it'll only be 2 dimming channels for 3 drivers. So hopfully it'll be a decent look... My UVs were optic free.

Stevesleds has rebels I think that can be driven to 700ma all day long. He doesn't call them ocw, but they do the same thing. I will probably try them next myself.
