seems the newer bigger hlgs- Cs lose a little bit in efficiency compared to the 185s,120s.
good to keep in mind when designing a light.
HLG-320H-C3500 drivers out in april

so what # of cobs & watts per cob , configuration would u run off that single puppy ?
just trying to twist my mind to the #'s on the new stuff

my MO is to come in hot with less cobs at 50% efficiency (oh so horrible right, lol), and expand out to a more efficient array after first crop
phase 1 ($2200):
5x9 tent
3x HLG-600H drivers
24 cobs@ 2.1A, 75W per cob
~900 PPFD depending on bin (8x 3000k BD, 8x3500k CD, 8x 4000k DB)
1800W at wall
(6) 4.85" x 48" heatsinkusa active heatsinks, 4 cobs per (sized for future passive utility)
future: evaluate the 3 bins above and build out tent efficiency by adding cobs based on the results. so lets just say i find my magic bin/color temp and go with it
phase 2 ($2000 more):
same tent, same 3 drivers, same 6 heatsinks and add 36 more cobs and 4 more heatsinks and do 6 cobs per heatsink
60 cobs
max mode (1120 ppfd): 0.9A/30W per cob @ 62% eff
normal mode (880 ppfd): 0.7A/23W per cob @ 64.4% eff
key points:
-600W driver has a low inrush current (70A) relative to the HLG-185 series (55A each) and reduces ancillary electrical equipment
-600W driver is most efficient in class, 96% across the board from 50-100% load
-high current driver lets me run at any current i want, as ill prob change my mind 6x in the future
-not a woman and 17A@36V doesnt scare me

yes i mean the 2800 model. 3500 is a benchmark but an anomaly in our 36V cob world. it can run [email protected] at 84% load on that driver
obviously the 3 @ 2800ma using 98% of the driver is better

Meanwell emailed me a few days back and told me the first of May. Remains to be seen though. PAIRUI drivers that cutter supplies has a 250 version with amperages STARTING at 1400 and goes all the way to 4200. If you want high currents, you don't need to wait.

So Greengenes707, now I am lost. Bobby said 42V, For this 3 COB bar 36V @ 2.8 what driver should i get? 36 or 42V? Keeping in mind I am looking for a single driver per bar.
The 3 COB 300W-ish and the 2 COB 200W-ish.
JEEZ,
Sorry, Thanks mate

Are you running in series or parralel? That's your deciding factor. Go with series

I Stand Corrected The Rating For The MW And Inventronics Are 92% @120 And 94% @240

I like it man, damn i wish i had the $ to put up to build half that first light for my flower room.

It's disappointing, but the 240 preliminary data was revised before release so perhaps they will make some improvements before the 320 comes out.

looks like the new datasheet is much better, 94% at 230V

It looks to me, and I could be wrong, that one 320-1400 would run 6, 36v cob's? s my math-ish correct?
