. That is the front of the dimmer board. The back side does not have any writing on it. Sent from my iPhone using Tapatalk

Also I found this link to be able to use a 0-10v source to power a 0-5v. Let me know if this looks right. https://answers.yahoo.com/question/index?qid=20101031121337AAxGuxd Sent from my iPhone using Tapatalk

So between the black and yellow is were I get my 0-5 voltage. So that would mean the the black is ground the yellow or white would be the voltage going in and then either yellow or white would be the signal going back to the driver to increase or decrease voltage to the leds. Sound right. So since it is only 5v I should be able to take a test light and find out which one is my supply voltage. But now does the reef keeper alc supply the voltage to the driver?

I measured the voltage and it only goes up to 4.85 The model number is hp060a-vr. I did a Google search already. Sent from my iPhone using Tapatalk

I wrote this really late last night so a lot of you were probably sleeping if anybody knows what these three wires do and how I can hook it up please explain thank you Sent from my iPhone using Tapatalk

I just took mine apart and it has 3 pins not 4 on the dimmer. Yellow/black/white. Don't know where to start with these 120w Chinese led lights. Here are some pics of the drivers and wires. I am trying to use my reed keeper alc to control them with the 0-10v. Anyone shed any light???? Sent from my iPhone using Tapatalk

Inevo you have the link to the reef angle forum.??? AlanM this prob what I am going to do. Just connect the two on and off together then take the dim+ and dim- and hook up to the controller. So if I leave the dimmer inline I should leave the intensity at 0 right and just never touch it. Sent from my iPhone using Tapatalk

O and I forgot to add. Should I disconnect the dimmer or can I just tap into the wires. I would love to be able to put it back to stock if I had to. Sent from my iPhone using Tapatalk

Thanks man. This is such a great thread. So much work went into this. If I have any other questions don't worry I will ask. Starting with this. I have 2 full spectrum d120 I am just going to tie all the wires together so they work in sync. This should work with 2 drivers on each 0-10v. 2 drivers on the 1st 0-10 2 drivers on the 2nd 0-10.

@ALanM. I have the same fixture that you have. The d120. I am awaiting the arrival of my Da reefkeeper ALC. It has 2 separate ports of 0-10v to control the dimming. Now were you successful with shorting out pin 1&2 and hooking up Vdim+ pin 3 to + on the ALC and the Vdim- pin4 to the - on the ALC. Sent from my iPad using Tapatalk
