The power supply tends to crap out before. Ive hung 10000s of diodes by now, only diode ive seen die in our own place is china diodes (from 2017 so about 7 y o by now) lm561C, without heatsink. Everything else still lights up.
I still have a rig with 3500k LM561c ( original first gen quantum ) with current Slate 1 heatsinks and she is till going strong from late 2015 . I dont overdrive them so thats probably why it is still growing me weed.

Citizen COBs are same age as boards ( late 2015 )

Mine were Alibaba fotops, large boards, like 5 qbs side to side on wide side, with 2mm thickness. They seemed to run really well up to 200w with no heatsink but there must have been some kinda deterioration. Alibaba quality obviously not the same as hlg. Not having a go at the diode infact im cool with them lasting how long they lasted. Though the same type of board but with baba 301bs are still running fine with minimal loss of output.
