They didn't claim a brand. I've been hunting for some time trying to figure out what they were because I don't want to go through the process of building out a frame for diodes under 140lm/w. I'd really like to plot their efficacy or come across the data sheet so I can calculate a build.Those are not 561C or Lm301B.......The LEDs you have pictured cost about 1/4 the cost of lm301B ..... Or 1/3 the cost of lm561C. Where did you get thrse and what led did they claim to give you?
I tested them (in parallel) on the board @ 6v+ each so I know they aren't LM301b or LM561c but was curious what the dissent would be given the threads attention to ESD visibility.
Data:
12S/3P, 30w (~kilowatt reading)
- .38A measured in series between negative driver lead and board.
- ~73v measured in parallel at driver leads before board.
- ~6v measured in parallel at diode terminals
Was hoping they were similar to these...

Thanks for the reply and any insight!
Seems like theres quite the demand for top bin, they can't all be, I'm sure your lights are superior to the Chinese ones. If these will get me through a grow I'll be happy, though not as happy as using one of your lights haha If I had the cheddar, I'd be buying prime cut, I've heard nothing but good reviews about HLG when it comes to quality.
EDIT: How could you tell they weren't lm301b or lm561c? What was distinguishing? What are the visual characteristics of good 2835?
