Im also doing a large LED built with Modular LED. Building my own heat sinks 39" x 12" & splitting 272 LEDs per heat sink, 5 -120w drivers, 2 - 75w drivers, 2 - 38w drivers and 6 - 120 mm fans all controlled by my Profilux 2EX controller. Using cool white, cool white HEW, nuetral white HEW, blues, royal blues, red, green & XP-G cool white for high noon kit.

I really want to see what mix of colours you use. Ponokareefer's colour selection was pretty good and I'm hoping to see what you do.

Plus, 272 LEDs per heat sink?!? Like, OMG, dude :eek: :eek:

lol thats like brighter then a metal Halide!

Hope to start building this week. It's going to be 272 LEDS TOTAL split on to 2 large heat sinks for my 300 gal 8'er.

thats a big build Greg! I hope to get to that point someday *insert positive star wars quote here*<--- "Much learning you have still young padowan!"

You have no idea Grasshopper :lol:Watch for the build threads.

Some info on LED color choices

Royston?

That's a good link. It saves you from having to read the huge RC LED aesthetics thread it references.

I went with 56 LEDs on 2 heatsinks, 14 rb 14 b and 28 cw. The colour is ok for now, I still feel it's abit on the dark side with lenses in the middle and edges. I am also running 2 overdriven t5 for supplements. Not discoish at all now but may add more regular blues to get a more 20k look, right now I would say it's a 12k look running the t5 and LEDs.

Hey Rob, LEDs are running for about a month now. I ended up melting and bleaching a few montis like my forest fire digi, pokerstar and rainbow. The lenses really focus the light. In the next few weeks or maybe after the new years I will be turning the cw up to 1000ma, currently all running at 700ma. As for the sps they have colored up alot more under these lights, the LEDs sit about 4" from the surface with 80 degree lenses, acros are about 4-6" under the surface. I am happy with the LEDs for sure!
