Random thoughts from the peanut gallery on channel distribution. now this is based on no numers other than gut feel but why not something like

CH1 WW WW WW WW CW CW CW CW CW (not sure if 8 was doable on the channel if your going with 2 in series)
CH2 5 Reds
CH3 5 blues
CH4 5 Greens


theory being CH2-4 combined full light will give basically white if the right LED color spectrums are setup, when added to the CH1 Whites it should give full spectrum balance, with adjustment on coming from the RGB if different color temps are wanted.

other theory how hard would it be to go 5 channel with the thought of 3 being strung together? then just go 4 LEDS each of WW CW RGB on there own channels.

if 6 per channel is needed. another thought again just my uneducated idea.
Ch1 WW WW WW CW CW CW
CH2 5 Reds then a WW
CH3 5 Blues then a CW (maybe a 10k? or other blue heavy white?)
CH4 5 Blues then a CW (green heavy white? is that mint?)

the reasoning on the second layout is same as the first, but with the thought that i can't think of any reason you would need any color without some white mixed into it anyway so putting 1 white on each of the RGB channels will allow for spectrum adjustment, while still putting enough White LEDS on the board.

well was poking around on evil bay...and found this. So my last idea above might kinda be recreating the wheel, no idea of the quality of the leds though...but if it really takes 1amp per channel this thing is 150 watts if fully powered up? just thought it was a kinda crazy chip, optics on it would be equally crazy I would guess looking at dimensions



channel 1:XPE white 6000K 29-31V 350-1000MA
channel 2:XPE green 525NM 29-31V 350-1000MA
channel 3:XPE red 620NM 22-26V 350-1000MA
channel 4:XPE blue 470NM 29-31V 350-1000MA
channel 1:XPE warm white 3000K 29-31V 350-1000MA
SIZE:82*66*20MM

You never know if those chips on evilbay are the real deal or not. Likely a cheap knock-off
I would personally not want warm white and cool white on the same channel so you can adjust intensity of each to adjust the overall look of the tank warm and cool wise. I've got a bluefish mini controlling my diy led build with warm white, cool white, red, blue, cyan, and violet. Nice to control all individually. Definitely interested in these chips

Spent a few hours polishing this design up a bit....



Now we'll have our choice of 4,5,6,7, or 8 independent channels! I chose to forgo the use of a pretty wire harness for the flexibility of plain old solder pads. The Pcb measures 49mm in diameter. Take a look and let me know what you guys think?

That looks great. Definitely would be interested in 6 channels

Ok Jeff... You're up to bat again. Seeing that I've got the Leds divided up into 8 groups of 3. What do you suppose would be the best led color/channel mix? From the color palate that you posted above, would it make sense to use at least 1 of each color wavelength in groups of 3, i.e. a "red" group( 1 far red, 1 deep red, 1 red ) , an "orange" group" (1 red orange, 1 amber, 1 PC amber), a "green group"(1 mint, 1 lime, 1 green), a "blue group" ( 1 cyan, 1 blue, 1 royal blue). Then fill the other 4 channels with a equal mix of cool & warm white leds? I'm using the BlueFish mini right now, so 6 control channels would be perfect for me. In the future, I'm planning to switch to a custom built/programmed ESP8266/PCA9685 based controller with 8 channels.

See above.. done..

Technically more of a 7 channel design..to get to 6 channel just group 3 w/ ch8 ...

Estimated CRI w/ blue channel dimmed is over 95

ch1 6CW (6000-7000k or greater but not more than 8500),
ch2 3ww (2700k) 3 4000k white
ch3 3 deep red
ch4 3 cyan
ch5 3 far red.
ch6 3 blue


rough estimate.. as I said dimming blue increases CRI..

This is looking really cool. I was thinking on it on my drive to work. Curious to see what Jeff comes up with. I pictured Channel 1&2 bein Cool White Channel 3 & 4 Warm White like your thinkin 02 I think, but was unsure what to do with the other 4 channels. I was thinking Red Mix Blue Mix Green Mix and maybe a 12k White Channel?

Edit I see Jeff has it coverd only change i'd see to his layout is making WW and NW on the same channel pair so they could be combined if run in 6 channel mode.

Notes: had to use 680 red instead of the 700. Whites are of course phosphor dependent. Diodes were 1W so PAR w/ 2 or 3 w drive current will be 2 or 3x as much..

Pretty much can dial infinite CRI's and tones...xcept violet.. )
no independent royal blue since it is the pump for all whites..


Not sure it is best to group the rgb channels close (since rgb=W) or intersperse them..
Leaning toward interspersed..

Like 12, 4:30,7:30 ish RGB

Alrighty then! I'll finish the board up and add the led color positions to the silk screen before a I send the design off to China for production. Looks like Digikey has most of the Luxeon C colors in stock, so ordering them won't be problem. Just gotta wait till after the holidays. The wife and kids have been rough on daddy's wallet lately- LOL.
