Even though I rated 4 stars its still worth a great buy. Strange, I ordered different colors of this COB. Red one had its heat sink back connected to positive terminal. Royal blue was isolated… Well tried to drive all the way to 3 W and the chip flashed and burnt out even though it was reflowed onto a 1/8″ thick copper slug (1″x .875″) then the slug was screwed into an aluminum block with thermal grease between the copper and aluminum. chip didn’t even feel warm when it flashed and died. Around 900mAEven though it may not…
