Need to get back to you on the GHL. Not familiar with them.

@theatrus did you get my email sir ?
It's pretty much the same 0-10v set up rj 11 connections . I have their breakout box that converts the analog voltage to pwm but it's 0-10v also, which sort of worked but not well.
I consider making a little voltage divider to halve it to 5v but I figured I'd try your board out
I'm planning a light for a 3.7g AIO cube. Debating between an AcroStar Shine or a totally DIY array. For that, I'm currently thinking a 7 LED array with 3x Luxeon RB, 2x Mint, 1x Cool Blue and 1x Hyper Violet from Steve's.
Reading through the threads, I'm thinking it makes sense to drop one of the mints and add a PC-Amber.
1x Hyper Violet
3x RB
1x Cool Blue
1x Mint
1x PC Amber
Trying to figure out how many channels of control I'll want on this as well. Also debating between 7 individual stars or 2 3-ups plus a mint. If I went individual, I think my fixture would be around 3.75" in diameter. That'd give enough space for the stars plus the thickness of the fixture. I'd be using a combination of aluminum, walnut and acrylic.

Only difference between lime and mint is the mint just has less "green" phosphor allowing some of the blue base emitter to show through..
This isn't that important unless you have a specific need.
pcAmber is to "hit" the mercury spike present in most metal halides (well err 14000k or lower)
lime for the green spike..
As to channels .. the more the merrier.. only usually has to do w/ cost.
There are some colors that group well together but still limits one..
Ideally it's UV/viol/B/(Cyan/green)/(red,orange,yellow)/ir..
but obviously overly complicated..
blue/lime/pc amber creates a sort of magenty white..though one would generally need the blue to not run at "full"
Theoretically now just add a rich blue channel...
Should cover all the main absorption peaks and add enough coloration.
Theory can only go so far..
All depends on exactly what you want..

Import a CSV or text file in the DATA: FILE: import:SAVE w/ adding lumens and beam angle..
This is the raw data for a Viosys 420nm violet.
MUST start at 380.
380,0.005
385,0.005
390,0.013
395,0.046
400,0.114
405,0.255
410,0.551
415,0.798
420,1
425,0.721
430,0.397
435,0.228
440,0.108
445,0.06
450,0.034
455,0.016
460,0.008
465,0.003
Download and use Notepad++
Make sure you don't have any diodes in the data b4 uploading new data.
Can't "miss" a step.. except at the end...Need 5nm increments or data won't load correctly.
You can create the data w/ Webplotdigitizer.

Anybody have the data file for the luxeon k16 that I can upload to http://spectra.1023world.net/?
Trying to figure out webplotdigitizer so I can get the data for the Citizen cobs I'm using too. Not having any luck.

Just use the Rebel royal Blue and adj to 9350mW output
already @ 450 peak.
10.3 Rebels = one k16 in radiometric power.. 9350/909
you can use fractions..
As to citizens...what is the issue?
Solid colors like rb can sort of be faked.
Whites are a different story..

Awesome that helps a lot!
I believe all the necessary cob data can be found here: https://cobkits.com/product/citizen-clu048-1212-80cri-gen5/
I'm just not sure how to get the data for the 3000k and 4000k cobs into the spectrum program.
