And all I am saying is that I never said less watts was one of them

Perhaps you should write a stern letter to Mean Well correcting them.

ha ha..............this was all avoidable, my faultAnd all I am saying is that I never said less watts was one of them
with resistance/voltage drop/copper loss we're talking about a miniscule diff in favor of 240v ...........I should have worded it better or not even say anything to begin with!
No, I'm not writing any letters, lol.......3% is possible, just have my doubts
I would like to see actual, real time kilowatt metering done on a MW driver 110/120 vs 220/240v at 90% load.......seeing Dawg's recent temp casing tests , the driver manufacturer you chose is way more important than volts run

Yeah I'm sitting here like damn WTF did I ever do to PSUAGRO. I never said less watts lol.......it's all good bro

I'll do it when i get time. That behavior is not at all uncommon, power supplies are almost always more efficient at higher input voltage. the components are designed to operate in a given input range.without tearing one apart it is likely that 120V has at least one additional step-up in there to get to the proper input voltage of the main circuit - every step is lossy.

i been looking for a killawatt that does 240v,find me one and i will buy itha ha..............this was all avoidable, my fault

European kilowatt 240v meters will work with cheap travel plug(s) attached.........but 50 hz vs 60 hz(US) might skew?, not sure
fluke or bust

The answer was yes. And then no. But maybe yes again in a few months.Is This A Vero Killer? You Know What I'm Going To Say To That!!!!!!!!!!!!

it is interesting to look back at all the early 'on-paper' speculation in this thread that was later disproven. stuff like
and that pecking order is almost entirely a straight up order of # of dies per chip
when in reality at just about all currents its 1212<vero V6<CXB<1818=vero V7

@CobKits The DS93 gen 7 data sheet looks really good on paper! I really like how they've listed each cobs efficacy at a range of given power levels, respectively. Some cobs are exceeding 200 lm/W
But I don't understand how to power them in the real world? It looks like there's low voltage, medium, and high voltage cobs, and the voltage can be varied at a constant current? Is that right?
What kind of driver is suitable?
I would like to run eight of the low voltage type cobs at ~36V on a Meanwell HLG-320H-1050A. Would that work?

Yes.
So would 4 clu048-1818c4 be optimal on an hlg-240h-c1400a? Have 8 of the hlg's and 24 fcopto luna100's that am planning to get different power supplies to run so am looking for better possible alternative to run on the 180v/240w/1.4A. Any ideas? Threw in the luna100 data sheet because it is similiar to the citizen.
