LED linear array replacements??

[Strouty]

I can't really find much on this subject. I have some TCP high bay light fixtures, some have several LEDs that are dead, others have entire arrays, curious to see if anyone has had any experience fixing these? I hate to buy all new lights for no reason, the replacements are an upgrade, but I still think it would be nice to find a way to fix these without trashing them. Here is the LED array with some of the tags that seemed important. They are from a HB150 light (at least I think that was the model), any input would be appreciated.

Never fixed an LED lamp before, but I have repaired LED arrays in the old infrared illumination rings in CCTV cameras. Probably the same principal. Depends on how the arrays are designed, but in the camera boards, they were wired in series groups. When one diode would die (open), it would take out a whole segment. Usually 5 or 6 LEDs. Find the open one, replace it, and the rest come back.

In your case, if the whole strip is out, check the incoming power. If it's just a group of LEDs within a strip, one LED within the group probably failed open.

If you're really bored, and have SMD soldering experience, you could probably sacrifice one known-good strip and have enough SMD LEDs to fix all of your dead ones and have plenty to spare.

I figured if I could save half of them it would be worth some effort, I found replacement lights for $130 delivered for two lights. I bought some to see how the quality is compared to these, my guess is I won’t know how good they are until after they have been up and running for a while.
