Led guru needed

I’ve condemned two old Mars hydro 300’s.
each light has 2 of these drivers. Is there a QB that I could power with these? I do have heat sinks and fans also. Thanks C6CD5FAC-5771-4289-99B0-37495FA2229B.jpeg

Administrators if my thread needs to be moved please feel free to do so especially if it helps me come to a conclusion

So not really up to date on the newest qbs but it seems like those drivers wouldn't be the best for boards. Most boards run around the 48-54v range from what I remember. Those drivers operate from 55-86v range at around 650ma which even if they did fit the voltage would run them extremely soft.

That said, if you're dead set on using those drivers, there are probably a bunch of options for strips you could look into. The 650ma current seems to fit right in the nominal range for some of them, bridgelux strips for sure. Youd be able to fit like four strips per driver and not even need heatsinks if you wanted, plus they'd most likely be cheaper than boards and be getting more watts out of the drivers.

Sorry I'm no guru like you're looking for, but hopefully the more experienced guys will chime in for you. I did take apart a free kind led I got way back that had cheap drivers like yours. I never "used" them but did play around with them and test some strips out for a bit with them. I may use them one day for some small shelf houseplants I have going though.

Its not a lot of watts, up to 60ish per driver. You can use them maybe with some strips for veg or clones. Youd need something with 55-88V, the higher the better, and which runs well on 650mA. Bridgelux eb and vesta strips comes to mind, you could strap 3-4 on each driver depending on generation.

Oh man thank you for your input. That’s the info I’m needing. .65 amps... I was thinking the same thing that they would be running quite softly

Old LED lights and components are also good for shop lights etc. The housing and backlighting strips of my old TV now help light my garage. They are quite blue, must be 6500k or higher so they'll go in the tent if I have a stretch problem!

Easily repurposed.
I've cobs, QB's, Growgreen boards, Epistar monos and F strips run on those type of drivers.
Running soft they're great for side lighting.
