It's a very high CRI so the lm/w will be down becuase it has a lower LER.

Bingo..........repurposed chip, mainly used for film/photography as you know.......

If you use the 500w chip at 100W with a hlg it is going to be much more efficient...
I believe that Cree is going to sell soon biggest cob( I hope!)
Have a nice day

Hmm I wonder how the efficiency would be dimmed all the way down to 350ma.

...bicit... ...how the efficiency would be dimmed all the way down to 350ma... on actuals cobs?...
...on other hand... i dont like if on datasheets the leds are tested Ta = 25ºC ...not realistic ...not ok from my pov... ...the efficiency datas are missing on alta led datasheet... LER values same history... ...maybe im wrong too... ..........im
today too...
Saludos

There is also 100W cheap chip(to put on your sheep...sorry for this) on alibaba(with more than 40 thieves...)if I ran some at let's say 7W @175mA maybe it could be efficient enough(for the price of 1 Vero13)

do your sheep need headlights ?
ask them if they have a low cri version for better efficiency

If you get a chance ask how much the 5050w version is.
The hlg-600h-42b is large enough to run the beast

Well the 36v cxb3590's dimmed to 350ma are well over 60% efficient. So maybe some good things to expect from the 500w version

Sweet ... I'm pretty close to them too . Looking to hear first impressions of COBS.
And some real world tests. Maybe a Heatsink mount for a bench test run .

I was gonna post that lol
maybe its just the video, but the coverage distribution is horrific. I see shadows all over the place correlated to the lights center focus.

I see why we don't see a lot about the Alta chips they run $4 per watt and the fixture HP4S $2895
Ouch
