4 x clu048 1212c4 with hlg-185h-c1400a
Hi all, I'm considering a build using 4 x clu048 1212c4 with hlg-185h-c1400a driven @1400mA. The driver selection tool says it's cool, however the datasheet suggests that one should use 1080 mA. Also, according to the datasheet, at 1400 mA the voltage on the cob goes to 37 V, so it would put it outs...

Re: Dimmed high current driver vs lower current one
Thanks for your answer, Kiwi. 2800mA is outside the efficacy range of those Cree's you mentioned and 95% of other cobs too. Oh, O get it. I guess I misinterpreted the relative luminus flux graph from the cxb3590 data sheet: Screenshot_20180415-090655.png See how in the example they calculate lumens ...

Dimmed high current driver vs lower current one
Hi everyone! I'm new here and about to start my first COB build. There is a lot of info to assimilate for a newbie, but I'm doing my best ;) I can't seem to find straight answers to a few questions regarding dimming the COB drivers (lets consider Mean Well hlg-c ones). I will present them in a form ...
