one of my led boards is failling. few rows dont light up completely. @Death The Cultivator or anyone know why this could be?
It's not so evident at 100% but dimmed bellow 50% is whwre is can be easilly seen.

Think im gona go and check how long its been like that now by veiwing my old threads.

The LEDs/rows are surely wired in parallel, not series, so all do not stop working if a single LED or circuit cuts out. That is, the working LEDs/rows should continue to perform as expected.

The overall loss of light output will be rather low, if only a few rows are out. But for me, multiple failing components suggests it's time to retire the light.

same here... they just turn off completely when the lsmp is dimmed low. im hoping it's just the dimmer thats failing but im having a hard time finding one here in my country

So... jus t a little update.... I bought three new dimmers hoping the problem was the dimmer... doesn't seem to be the problem.
Still works as a seedling/clone light though. So not to much is lost.
