Hi guys I posted something a short while ago but it got lost to the ages so to speak. I bid on an assembled board that has 378 diodes and is labeled as a 135 watt board. It needs a driver, a frame or heatsink. It is just a board with diodes. If I got a constant current driver would 100 watt be too soft? This diy electrical is VERY new to me but posts here have been informative even if I only understand less than half of it. I hope it will go as simply as it seems, haven't gotten the board yet should be here the 16th and I would like to have other components ready...do I really NEED aluminum heatsink stuff and if so can I buy this in what, specific dimensions?

Photo of the board and any markings. Its impossible to know what to hook that thing up to without more info on what voltage it runs on. You will need a heatsink in all probability or it will burn out diodes

We do not know what drivers were running these boards previously? We do not know what forward voltage range for the red or the white diodes is either? Google/image search for HEKA-382-HYBRID-GROW brings up nothing. Suspect the vendor that sold them to you does not know either. Its a pity the drive components were seperated from the lights. Did you get the heatsinks that are shown in the vendor images with the red channel lit up?

Braver hobbyists might hook those channels up to a beefy bench supply and carefully crank until signs of life appear. And try figure suitable drives for the two channels.

The Heka leds come up on youtube.

Id just try with what the supplier said: a 24V 100w driver.
Go for meanwell xlg-24-A or AB but at own risk. If you want setup advice tag here. I dont really do driver setup advice on PM, but tag me here.

Ties in with the date on pcb. Wonder if number still works? +1-866-7420420 @Aapoo

Oops, no. I was supposed to say xlg-100-24AB.

Go to octopart.com and copy/paste into the search engine and youll find suppliers and prices. As i said, own risk but by the info provided this should be it, it can be adjusted a bit in voltage so should be fine. The red diodes will run on something else, no idea what.

Thank you sir for looking into it. Your response leads me to believe that maybe my decision to buy it wasn't so wise after all.
