Nice Work.Your heat sink is very impressive . How's the temperature of your led light when working ?Yes ,Cobs make things wayyyyyy easier ....
Yeah,I sometimes can't get over it myself,when I look at them !
And they still work fine ( Although I've managed to destroy one of the pcbs ,in one panel,by accidently decapitaning
the lens dome of couple of Oslons on that pcb ...Tiny and very sensitive ...)
Reflowed ,at stove ,twelve Oslons at once per mcpcb ....
9x mcpcbs ....108 Oslons hot-plate reflowed...
Yeap...It was 'challenging ' enough !!!
But ,for sure they're great little ones ,those Oslons !

I love how the picture of the maximum power shows how the light completely washes out the floor tiles. It is so bright! Can you feel heat from the COBs on the light side? Can you see through your hand? hehe
Interesting info on your cooling methods SDS, remember though that in refrigerators/cars(when not in motion) the air is PULLED through the fins because it also cools the compressor/motor behind the fan at the same time=== cheaper design, best cooling method??IDK,
yeah that a significant temp diff on #3 cob^^ wonder if the "HOLDER" is the issue?? not everyone running cobs has the luxury of checking temps real time like you, well a cheap IR temp gun would be accurate enough to check for a flaw I guess.
Your panel is just damn sexy, can't wait for the grow under it..............be safe grower
Pet,please 'break your question in pieces ' and repeat ..I've been seeing more driver chips (ICs)
Are they game changers?
Integrated circuits... replacing drivers
