    Yeah I have seen that on their site before. I didn't want to have to start playing around with fuses with a parallel setup though... but I suppose it wouldn't really be that much more complicated. Does this look like a decent setup for a 36 LED panel running off of 2 drivers?

    Thank you very much for all the advice you've given me so far by the way!

    No problem, glad to help.

    Your wiring is right except for that's not where the potentiometer goes. There is a second set of wires on the driver for dimming. You hook them up to a pot and a 10K power source.

    I wouldn't run the white's in parallel. if you're going to use that many, you would want 2 drivers just for the white.

    With a 1:1 blue/white ratio, I'm guessing you'll be a lot closer to 10K than 14K.

    Hrmm... Just when I finally thought I had it all figured out! What kind of a ratio do you think I would want in order to get to approximately a 14k color? How many XP-G whites would you say can reasonably be run off of a ELN-60-48D driver? If I went with a 2B:1W ratio then I would think I should be able to run 12 whites off of a single driver... is that a correct guess? But is that going to end up looking extremely blue?

    Does the potentiometer need a power source in addition to the driver then or does the power running through the potentiometer replace the power source that runs into the driver?

    Thanks again!

    Yes, if you went with a 2:1 ratio you could get buy with 2 drivers. 1 for the blue and 1 for the white. The 2:1 ratio is also what gives you the 14K look. Look at the pics in my build thread and you will see that the 2:1 looks very similar to my 14K metal halides. 14K is white with a hint of blue.

    The potentiometer works in conjunction with a separate power source for dimming. It hooks up to a different set of wires separate from the input/output lines. So yes, you do need a separate 10V source for dimming. A single 10V source can be used to dim all of the drivers. You will need 1 pot for the white and one for the blues.

    Progress is under way! I have my first string hooked up (12 XP-Gs). Here they are running at 1.2A. Where did you get your mounting rails and project boxes from? I'm definitely going to need something like that to clean this up when I'm done.
