Driver for my qb

[WhiteRecluse]

Sounds legit and I like the arrangement you have in the picture. Keep in mind you will have serious hotspots if you space them so close in a 5x5. You might be better off doing two runs of 3 for more even spread. Also, you might consider using two 4k in the middle of each 3 spread and 3k on the outside 2. This would give you all around 3333k ish. But the veg lights would be veg spectrum. And come flower you are turning on 3k flower spectrum.

This is assuming you are running autos or SoG as implied by the 14 day veg window. The added red should certainly help also.

Happy growing.

3000/4000k mix 1:1 is meant on 1x QB so 144x 3000k/144x 4000k chips
so light color temp will be equally spread on each panel.

(on other thread someone was writting me that is no sense to mix 1:1 as its the same as 3500k, but 4000k has more blue so plants could grow a bit more i guess )

Panels have AluHeatsinks to it should take of the heat - i can install also temp sensors on each panel to know the temps.

The panel setup u were describing is like i put on picture?

Thanks

Sorry, I misunderstood your intentions. Mixing spectrums on the boards themselves will be much more beneficial than what I suggested. That picture represents what I suggested exactly.

Making 2 separate modules allows for easier management of the lights. Also assuming the boards are roughly 8" x 12", you should have 12" between each light or very close in that config. Thus giving you better spread and less intense hotspots.

Frame is just example - but i want to build something similar , i keep in mind that distance suggestion

QB size should be 286*174*1.6mm

If i would do your 2x frame setup i would need to put 3x drivers for those panels + 1x driver for RED chips

With my frame plan is 1x driver for 2x middle QB and 1x for 4x QB on sides

The thought crossed my mind about the awkwardness of mounting 2 drivers in that configuration. Another thought was to use 320h on each run of 3 but then you would lose total wattage as the 320 is an odd interval compared to 240 and 480.

I have relocated drivers outside the cab so it isn't much more visually unpleasant to hang lights independently for me. I have a 3" piece of wire attached to a wago on every QB + and - lead. When I go to remove my lights to clean or whatever I disconnect them at that wago (with the power supply unplugged!). This works well for me and I haven't had any issues thus far.

The biggest drawbacks to having everything mounted in one unit is size. It will generally be either to small and not evenly spaced causing serious hotspots or too large and a bugger to adjust height or manage by oneself.

yeah the total size of such frame (6x QB) will be large and maybe an issue to hang it first time.

So the idea with 2x frames (3xQB) could work as you mention will connect the same 2 middle QB with HLG-240h-48b and later for Flower 4 rest QB with HLG-480h-48b,


BTW what is the difference between: HLG-240H-C2100B vs HLG-240H-48B i regards of powering QB.

Thanks

Slightly higher current on the -48. 2.5 amps per board wired in parrallel vs 2.1 amps per board wired in series.

Ive checked here
https://led.meanwell.com/webapp/product ... d=HLG-240H

its mention is like "12V/15V/20V/24V/30V/36V/42V/48V/54V" but they do also MODEL marking with "AMPs" values

so is 240h-CXXXX (and silimar) some new way of naming?

[WhiteRecluse]

HLG drivers labeled -c1050, or -c2100 are constant current. Drivers labeled -48 or -54 are constant voltage.

[psyweed]

aah ok ...

So either by counting each panel Current (AMP on -CXXXX series) or Voltage (48 / 54) i can pick right driver

so for 2x QB both could be right:
a) HLG-240H-48AB
b) HLG-240H-C2100B

interesting...
