Ya, @welight what driver would I need to run all 6 of these PCBs @800ma? They use 1 of the drivers I'll post a pic of for 2 of the 6 pcbs, totalling 3 drivers.

Hard to say just from the pic, but I'd agree with you airwalk that if they reconfigured where the 3 main drivers were, there would be more air flow from the side vent. Maybe keep the 3 drivers in the middle and place the fans on the outer edges where the 2 outside edge drivers are. Then the fans could actually move more air freely. It seems like it would breath good if the fans and the 2 outside edge drivers could swap spots. Thanks for taking the time to crack her open!

Fans can't be moved buddy. They've got corresponding holes cut into the top piece of the fixture, giving them only 1 spot to be of any use.

Now that I think about it, if I mounted driver on top, I'd use a 240-2100b for the 3 cobs. Might as well get the extra power if I'm making it easier to cool. I'd cut a new hole in the top and put the pot affixed to the fixture. It'd be dimmed almost always.

I'm pretty sure each pcb has about 41.5v of forward voltage. Xpe data sheet says @700ma red are 2.5 & blues and whites are 3.5. So with 11 reds and 4 blues and whites I come up with 41.5? So 2 together is ïroughly 85fv. Am I correct? So 85x.8 is roughly 70 watts for each driver? So all 6 pcbs and all 3 drivers each running 2 pcbs would be 210 watts?so a 240-700 would do it am I correct?
Or maybe even use a 240-1050B and just never turn it up all the way? Xpe can handle 1000mA it looks like on all colors and types from the data sheet. I doubt the extra 50ma would honestly be of that much ill effect anyways though?

Didn't mean so much for you to do it, but maybe a suggestion for Eco to consider if/when trying to better their product. Sometimes it takes real world experience with something before an issue is realized. If its holding that kind of heat it cant be good for efficiency or longevity though.

I don't know about 800ma, but looking at the driver output it's similar to an LPF-60 either -36 or -42

I don't want similar. They use 3 drivers... each running 2 of those pcbs. So I wanna know what to use to power all 6. I'm almost positive I need the 240-700/1050B.

I posted pics man. It's a wire harness type connector.it's snaps on to another connector piece.

CXA3070 we run actual wattage is 50W . The actual power is higher , higher wattage give off much heat , which is normal . But our users grow with our units are happy with them comparing to their 600W HPS .

What wattage are each pcb running at that you put 2 per driver? Or more so, what is the forward voltage of each individual pcb mono cluster?

CREE COB CXB3070 , we use 1.5A ,24-36V driver . The driver is UL standard .We tested the temp for the whole led light ,CREE XPE Channels is about 180W , CREE COB channel is 150W , we want the more coverage and higher par and lux as possible as to make the whole light , powerful and higher par .

Maybe your DIY together Our COB LED 3 make the temp higher than only under your DIY . If you seperate them and check the temp, you will know .

Okay, so each pcb mono cluster is running at about 30 watts at 700mA meaning the fV is 42. Holy shit my math was right. I just got watts and FV mixed up a little down the line.

No. It's absolutely your cobs. You packed too many drivers into a small space. The flow for air to travel out through the sides effectively is almost impossible. It was nearly 90*F until I turned the cxb3070 cob channel off and dropped to about 80*F when just the xp-e channel was on.

CREE XPE 3W , its mix mA is 1A , we run 700 mA,which most chinese led chips cann't stand .

When we designed the panels , our customers want high power and bigger coverage unit , which make us to develop panels like that . Increase the power , airflow is OK to cool the heat from the leds .
