I googled QB288 wattage and it popped up 75wattsnfrom HLGWhere did you get 75watts?

Flux Characteristics with QB 288 V2 3000K, S6 Bin at 55CI googled QB288 wattage and it popped up 75wattsnfrom HLG

The boards in the hlg 550 are ran at 2300ma. The VF is around 51 VDC. So you are looking at about 117 watts per board.This might be really dumb question but.. If the hlg 550 v2 are 480w.. And theyre 4 qb288s.. And each board is a max of 75watts... Whats powering the other 180?
@Stephenj37826 With these meanwell AB type drivers; I see the advantage for a CV driver, where if you'd normally get the A type to have the voltage adjust you'd also lose the ability to dim externally, now you get both abilities (right?). But what's the advantage for the CC drivers that are AB type? Does it add an internal voltage adjust potentiometer where there normally would be one or something?
If anyone know and could explain.
Thanks.
Those ledgardener meanwell driver videos are great. Don't forget, there's three parts to the main series though. And then there's at least one full video for A-type and B-type. Oh and there's a potentiometer and dimming video too iirc...@TravisG13 I've seen folks running these in parallel too using the 2 QB132's per 240h-36
There are some great videos on all this too, if you really want to understand what's what:
You saw what HLG says about the QB132 v2:
Driver Options
And here's the guide for 132s:
- LPF-60-36 - 1x QB132
- HLG-185H-C1400 - 4x QB 132 in series
- HLG-240H-C1750 - 4x QB 132 in series

You would use a watt meter to test for power being drawn, something like

Are you using Jacks?Between Growmau5, Led Gardener. and this thread is all in info you need to make you "armed and dangerous". I forgot about those video's on the hlg website, there "golden". These guys have great personalities for live/recorded material. I would make a debauchery of a video like that...lol
Are you using Jacks?
That is a clean setup! Well done.Working on the QBs and new exhaust setups ....
Fall indoor runs and time to get some grows going ....
Black tent is running the OG S5 quantum boards ( qb304 ) 3500k and Citizen Cobs ( 3500k )
Upgrade Time !
Rewired remote drivers .... decided to run 2 out the 4 quantum boards separately on a HLG-240H-C2100 each in parallel.
So now I’m able to have 480w ( ~500 ) on tap to throw at 3x3 ..... however I need to swap out older slate 1 heatsinks
for extended power. COBs are still on a 120watt driver and is also dimmer controlled. Each dual 304 is dimmer controlled
( on top of rig ) and will be monitored at wall with KIL-A-WATT meters ( ordered 3 ) . So looks like I will have at least 620ish in watt of beautiful quantum goodness .
These S5 boards are 4 years old and have been extremely reliable.... running perpetually until the last few months while I hammered
out a NEW CONFIG. If there is some “new“ boards that catch my eye then maybe I will retire the S5 ... lol @Stephenj37826 .

Green tent has the Dual QB96 with T5HO lamps with uv bulbs ...
320watt rig .. so far I’m happy with it as is.

Happy King Kong Poison plants in there transplanted bags .

The Batwing rig I built a few years ago is also running OG S5 boards and may get
these 90cri QBs .... not sure or may build another rig. Current power is 320w 3500k.

Yes you can run them. The 320h-c1400 will run at 47 watts, and the 240h-c1750a will run at 60 watts.I have four 132v2 boards sitting around I'd like to use. Can I run them on a 320h-c1400a? I also have a 240h-c1750a but wanted to run the boards at 75w each if possible with the 320h. Thanks guys!
