Just adding to the thread, my blue plus 150 OR3 bar stopped working today. Purchased new march 2022. Looks to be about the timeline everyone is getting from them. Probably not the most reliable units in terms of longevity.

How to repair the diodes any instructions? My OR3 UV 120 stopped and it's about 1.5 years old.

Fairly simple. Un-solder the bad diodes. You can find them with a multimeter. From there you can either just use a piece of wire or you can replace them with a new diode from here.
Yep, they're on my do not buy list now. It's a shame, I like the packaging, and how slim the bar is. But I only got 13 months out of one of my lights.
I wouldn't rule out the drivers going bad.
Unfortunately many are sort of "odd" electrical-wise and its not easy finding a substitute "exactly" like the original driver.
Since most are series/parallel strings usually only one branch fails open.
Driver for the 120..900mA is divided between 2 strands.. IF all the leds are out it is likely the driver.
Smaller models are all one strand so it doesn't apply.
As to individual leds yea just put a digital multimeter (pretty sure old analogs dont work) across the diode with the correct positive and negative. Led should glow dimly (maybe REALLY hard and not exactly safe to see w/ any true UV diodes) when set to either low ohms or diode function.
| 60W | DC 30-65V | 900mA |
For the 120 one could use the Meanwell LCM-60U with some "BUTS".
Original driver goes up to 65V @900mA. Meanwell is ether 2-72 @700mA (losing 200mA) or "possibly"
900mA at 2-56V.
The voltage will go to whatever is needed to get to the set point.
You would need to measure the voltage/current to determine IF it will run "normally" at 56V.
Good thing though is you add dimming..

Yeah it's hard to find. I tried one from Led supply but didn't work.I wouldn't rule out the drivers going bad.

HLG-120H-C1050A should do it if I'm reading the cut sheet right. The A models let you adjust the current.
