Luminous CXM22 w/ HLG 320H-48A Questions

What it do RIU,

What is the max number of CXM22 I can run with a HLG 320H-48A? Here is the spec sheet of the HLG. The CXM22's FV = 36v.

I just bought 8 CXM22 to run on 2 of these HLG Drivers in a 2x4ft space. Turns out, the area I need light coverage is actually 3x6ft. What would be the most cost efficient way to adequately light a 3x6ft area with 2 separate light fixtures? I would like to have 9 cobs lighting each 3x3ft section. Let me know if that is overkill.

Thanks!

I like the 1 cob/led/QB per sq ft.

As far as the CXM22 ( which i think those are 50v ) it just depends what amperage you want.

How hard you want to run 8 in a 3x3 on that driver HLG 320H-48A will give you about 800 ma per cob.

Its not an overkill if your lowering your amperage and using more cobs.

I dont know the PPFD of running these at different amperages per sq ft.


Cost efficient I think would be using what you have and grabbing two of the 320-48a drivers.
then push 4 cobs harder and cover 3x3 ft with each set of 4cobs.

GEN3 CXM22 are 50V chips. you can put as many as you need on that driver. Since it runs in parallel, there is no "maximum" really. after 70 chips or so youre down below 0.1A per chip where few people would choose to go.

most people run 4-8 chips per driver



id do 4 of those on one 320 in each 3x3. so your 8 cobs are good to go you just need another driver

I have 2 of those 320h-48A's already, so it looks like I should be good to go! I plan on having 4 - 2x2 trays in the flowering room for a perpetual harvest. Based on what I'm hearing from you guys is that 1 hlg 320h-48a per 4 CXM22s multiplied by 4 would be the best setup? And you mentioned wiring in parallel... You would do this vs wiring in series? Can you briefly explain the benefits of doing so?

Thanks!

Gotchya. That's what I'll do. I have 2 of those drivers so far so I should be good to go when I expand to have 4 - 2x2 flood trays I'll grab 2 more drivers and 8 more cobs so I will have 4 drivers with 16 cobs covering a 5x5ft area. I'll make sure to take a PAR reading once I have them set up!

Thanks for all the help!

You wont be able to run those chips in series with that driver. That is a constant voltage driver meaning you can put as many chips as you want on it as all it will do is take the Amperage of the driver and divide it by the number of chips. Wiring in series with a constant current driver means the voltage of the chips adds up but the Amperage will stay the same.

One benefit of wiring in parallel is that you could have 10 chips but only 50v will be running through the wires. Say you had a 10amp driver, 10/10 = 1amp each.
If you were to try this with a constant current driver rated to 1.05amps you would need a driver capable of running 500v through the wires which can become dangerous real quick. 50v x 10 = 500v
