>>1662003>reminder not to use driver-less stuff if you're going to be around the lights a lot, they fuck with your head due to flickering.I haven't had a problem with this, but it does mess with my camera. pic related. I did post in /diy/ asking if I could reverse the polarity on half my lights to fix it, but I haven't gotten any replies. I'll probably just try it and see what happens. I know the lights still work if they're wired backwards, but I don't know if it alternates the flicker timing yet.
>t. driver-less chinkshit led grow light owner.Commercial prebuilt? Those are usually just underpowered COBs with passive pie-tin sinks. Have you visibly noticed a dropoff in output yet? Have you tested light output? I'd be curious to see how quickly the unprotected LEDs degrade, since pretty much all the reviews I've seen on prebuilds say they get too hot to touch.
>you dont happen to have any idea how to screw cobs to a cpu heatsink, or should i just use thermal glue?I used to be a computer technician, and I personally don't recommend glues or tapes. Ideally, you'd want to use a silver based paste, pretty sure the stuff I got for the lights is aluminium based, but they stay pretty cool regardless. As far as attaching the COB chip to a non-compatible heatsink goes, aluminium is pretty easy to drill through. Technically, you should tap the holes, but I've gotten away with just driving the screws into untapped holes. The six lights on my array are all on oversized cutblock sinks with untapped hand drilled holes. It was kind of a bitch, which is why the infographic uses a sink with proper hole spacing.
