Did I overheat my QB? Broken QB

Aight, so to cap it off. I got replacement boards from KB. They gave me a whopping 5% discount, but since these are dogshitcheap I couldnt be bothered trying to get the price down. I did however get the ones with the epistars 660nm. Because the boards I have running here that aren’t broken are the ones with the epistar diodes.
Right now I dont have the bankroll to afford anything else anyway. I’ll see again in a year or so.

thanks again for you help guys, I’ll be looking into repairing the otherones in the oven. Magbe I’ll use them at a a low ampere for my aquarium.. we will see ..

try to make 3 to 2 for free, it may work out.
but good decission to get some new ones to be safe... at these prices.
even the epistar arent the greatest leds, seems these board will grow you some weed.

For now.. this will do.. I’ll be looking into better stuff once I get back on my feet financially. Like a said, these havent broken down for me yet so.. fingers crossed. Thanks for your help once again

So I had one last question, I’m now working on the two 240w boards and for the plants it would be best if i could combine one of each (one board with 660nm, the other with UV, 660 and IR, both by kingbrite) new QB on the heatsink. The driver is the hlg-240h-48ab. The qb’s are both stated to run at 48v. Is this a good idea or could I maybe run into some trouble?
