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.
One of my two OR3 bars just died, only 3 years of use. Very disappointed.

I wouldn't rule out the drivers going bad.How to repair the diodes any instructions? My OR3 UV 120 stopped and it's about 1.5 years old.
60W | DC 30-65V | 900mA |
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.
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.

Hmm which one?Yeah it's hard to find. I tried one from Led supply but didn't work.

No.. starts at 74v .To 148vHLG-120H-C1050A should do it if I'm reading the cut sheet right. The A models let you adjust the current.
This is the one I triedNo.. starts at 74v .To 148v
Low end matters as well w/ some drivers
4.1v would need to be the average V(f) @525mA.
700b may work
