Cxa3590 36v 145w 5000k

[AvidLerner]

What would be the best driver for two CXA 3590's? I saw a recommendation for HGL-185C-1050A/B . I am looking for a driver or pair of drivers to take advantage of these at the 150w capacity.

That driver will only give you half the current you need for 75W from each COB.

The HLG-185H-42 would give (max) 2.2 amps to a pair of 36V (nominal) COBs wired in parallel but Cree does not recommend doing that. If all current flows to one COB it would likely die.

A better solution might be the HLG-240H-C2100 so the COBs are in series but you'll be under utilizing the capacity of the 250W driver.

thanks for that. I will look into the driver you recommended.

#68 on two week waiting list.

I got it. and a couple of 50w Chinese drivers per SupraSPL advice to run them soft and see what happens.peace.

 

[AvidLerner]

I am now waiting for the 50W drivers to see how this CXA CoB runs soft, at 50W. peace

The consensus at RIU is 50W for the best compromise of efficiency vs initial cost/complexity.

got some passive heat sinks to mount them on. waiting for delivery to check. peace.

You'll want good passive heat sinks at 50W. I bought some ModuLED Giga (radials) but haven't assembled anything yet.

I ended putting these two COB's on a C700 driver to drive them at 50W max 25W min, and they perform well, along with the two CXA COB's at 77v. I got some Mechatronix passive heat sinks too for 50w max. this one ->https://www.cdiweb.com/ProductDetail/MODULEDXTRA9980B-mechatronix/574061/#.VxEVqDHz8gv
