Same current, 2X the voltage = ~2x the power
I noticed a discrepency in data; Can anyone clarify?

More power? This says to me that the quantum loss may not just be from Current. Higher Voltage seems to waste electrons also.what about the 7% difference in efficiency/>
i has the dumb?
Well, it's a double edged sword.....higher current means higher I^2R resistive heat losses.....More power? This says to me that the quantum loss may not just be from Current. Higher Voltage seems to waste electrons also.
If this is correct......
That is something I was surprised by too, you would think the high voltage version would have an advantage but according to the data sheet, not so.More power? This says to me that the quantum loss may not just be from Current. Higher Voltage seems to waste electrons also.

Cree CXA/CXBs 80CRI 3000K is around 325lm/W.Awesome thread! Finally all the spreadsheets in one place.
I'm trying to calculate my par/ft2.
Trying to find the LER for cxb3590 72v 3000k CB.
I will be running

Fricking roofing! That is one those things that I can easily screw up. I mis-calculated the hip transition the one time I tired it. I had to pull up a bunch of material. Really, I may take you up on this. I am buying this house that has an addition....well. Maybe I can just send you a picture in PM later on this year.OK my 36v cbx3590's seem to be brighter @ 700mA than the 72v although they do have different drivers, HLG 185 700 AND INVENTRONICS 160w quad driver 700mA. I've been wondering for a few days about it. If anyone needs advice on roofing I might be able to help you
Smoking green since 1970. I just noticed that. I graduated high school that year, and had no green smoke ever, until college in the fall.
No you are an old fucker! Anyway, I did LSD a bunch of times before I smoked pot.You are an old fucker
