Hi all, new here, not that new to Reefing. 150g for 4 years now, and a few 45g for a few more.
I'm wanting to ditch my DIY LED's for these D120's Planning 3 on my tank. Now I'm sure the Apex would be fine with 1 light, 1 channel per VDM channel, but 3 lights, I'm not so confidant. I cant have my Apex fry as I work in camp 3 weeks at a time and no one would be able to figure it out or repower my tank untill I return.
SOOO, to my question. I am planning to run a OP Amp per channel on the lights. And incorperate a pot for setting that channel Max brightness, yet keep the Apex program 0-100% for dimming. I have sketched what I think should work. Been about 20 years since I played with Op Amps so wanted someone to check it over. Plan on mounting the Op amp in the light housing. WOuld I be able to run power from one of the drivers or should I add a separate 10V supply to power the OP?
