Thanks for sharing!
Anyone knows how much more efficient the board is compared to a CXB3590 setup?

I made a comparison with 4 citizen 1212 gen 6. Board and cob same height and watt at wall from same driver.Took 29 point grid mesurements. Than I made addition of all ppfd from each point.
Total for cob was 19149
Total for board was 19718

EDIT:
Did more accurate test about passive cooling:
board 102 watt @Plug : T amb 23°C no air movement T board 45°C
board 119 watt @Plug: T amb 23°C no air movementnT board 53°C

Interesting, thanks.
So was it 2 boards running at those wattages vs the cobs?

Any hopes of the seller to make a packet (his pbc board + meanwell driver + wires and possibly an aluminum heatsink)? For people who aren't super DIY guys

Like he is selling diffetent cob fixtures

You could ask him:bigjoint:
I know he can sell kit,if requested.
He try to keep a low shipping weight.Driver add quite a lot of weight and if you can source it in your country may be cheaper.Right now I am using board at 115 watt with no heatsink and no airflow. Want to try at 2100ma and test if stay enough cool.Seller is doing some test using C aluminum as heatsink (customers can find C aluminum everywhere and it is cheap)

Cool. I might try to contact him once i decide to buy.i am from a neighboring country and could also order within italy (to a friend) and come pick it up. But ill wait for more testing. :)

Very interested to find out about thermal at 2100 mA as i allready have t drivers. Should be all right with some airflow/fans.

I will try a test at 2100.Again no air movement. If it stay below 60° C it should be same working temperature of hlg550 (that proved to work fine)

Nice! Ive seen some temp data on their web. All readings are done at 20c ambient. Would be nice to have readings on a situation more similar to an actual grow: ambient temp around 25-26 degrees, where led plants are more comfortable, and maybe some airflow over the boards. I think these boards could probably run happily with a small fan on them rather than a heatsink. It would sure be a lot cheaper: both material and shipping. Thx for doing all this @G84

Fan can have failure and need driver and cable.It is safer passive and also looks better:bigjoint:

Youre right of course. But when the heatsink cost is the same as the board, sourcing here locally its good to think about all options. Also if you setup 2 fans to hit both boards you can afford one dying on you as long as youre within thermal parameters. In any case im not sure id like to run the board muxh harder than 100w: the project im looking at now is open space enviroment and the closer the boards can be kept to cannopy the less light is lost.

Tested again
Board at 106 watt (around 1750mA)
T ambient 25.5 C
T board 45 C


Board at 128 watt (around 2100mA)
T ambient 26 C
T board 57 C


Test with 12 cm fan sitting on back of pcb
Board at 128 watt (around 2100mA)
T ambient 26 C
T board 32 C
Board at 150 watt (do not know A)
T ambient 26 C
T board 34 C
