Hi, Im just building a diy led light and I cant get my head around how to match the leds with the correct drivers. I currently have a 300mmx140x22 aluminium heatsink with a cree cob and im not sure if i have the correct driver for it. Can someone take a look for me please ? Il list the exact cob and driver below : http://uk.farnell.com/cree/cxb3590-...-3500k-12000lm/dp/2839916?CMP=i-ddd7-00001003 CEN-100-36 MEAN WELL | Mouser The heatsink is also getting very hot, is that normal ? Is it a good combo or should i get a different driver ? Ideally Cheers.
