seems the newer bigger hlgs- Cs lose a little bit in efficiency compared to the 185s,120s.no the new meanwell 320s are about 90%-91% per the preliminary datasheet in the first post of this thread
good to keep in mind when designing a light.

Bobbyyes which is why i went 600H its the best.
greater than 96% efficiency all the way down to 50% load
Bobby
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
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 driver3 cobs on the hlg 320-3500 model?
Dont you mean the 2800 model?
The 3500 will run constant in over voltage mode for 3 x 36v cobs i think , or is this no problem?
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.Read the data sheet man.
Are you running in series or parralel? That's your deciding factor. Go with seriesSo 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
I Stand Corrected The Rating For The MW And Inventronics Are 92% @120 And 94% @240I Believe The 240's Are 91% Efficient The Soon To Be Released Meanwell 320's Are 94% Just As The ECU-320 Are 94% Efficient. Yes They Are More Expensive With A Higher IP67
the 'C' in the HLG-320H-C2800 means constant current. which means if you put 1 or 2 or 3 cobs on there (in series) and they will each run at 2.8A. 4 wont run at all as the voltage is too low
the other driver (HLG-320H-36B) is a constant voltage driver (36ish). cobs are wired in parallel
you hook one up, it blows up
you hook two up, they blow up
you hook 3 up, they run at 8.9A/3= 2.97 A
you hook 4 up, they run at 8.9A/4= 2.23 A
you hook 5 up, they run at 8.9A/5= 1.78 A
etc
I like it man, damn i wish i had the $ to put up to build half that first light for my flower room.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
It's disappointing, but the 240 preliminary data was revised before release so perhaps they will make some improvements before the 320 comes out.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.
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?should be about $90 like the 320W high voltage drivers
