So a little over a month ago I finally decided to start my first grow, and also to build my first led light. After some (not enough, apparently) research, I went for 5x1212, on a HLG-240h-1400b, figuring they should just fit in it. Ordered via kingbrite. For the first week or so, everything was fine. Then the problems started. At first, a bit of flickering. Then the potentiometer started acting up - operating basically as a switch, and not well at that. I figured it was all just a bad potentiometer, fuck it, take it off, go full throttle. Took me another day or so to realize I was probably getting less than 100% this way too, likely due to tripping overvolt protection. Removed one cob from the circuit. Then the real problems started. Flickering - not the kind of mild rippling I had noticed with the potentiometer, where the light seemed to dip up and down with no real reason, but real on/off flickering. Took me a while to get an order of stuff I needed to rewire the entire light, but it finally arrived yesterday. Redid all the wiring - replaced kingbrite wire with thicker gauge wire, soldered new pot (two, actually) directly to dimming circuit. Not working. Light turns on, but is not as bright as it should be, and dimming doesn't work. Strangely, removing a cob creates the same result - not brighter, the way it did before. It does seem more stable though - no flickering. Anyway, took off the potentiometer, snipped the cable - no noticeable difference in light quantity. It seems like the driver is sending out low current as though its overvolt protection is engaged, even when there's no good reason. My thought is there is probably something wrong with the dimming circuit on the driver (or some other part of the driver itself), but also that I'm probably missing something somewhere. I don't have a multimeter but I can get one, and I'm good with a soldering iron but less with electrical theory. Help me, Rollitup Led Homies, you're my only hope.
