COB's for dummies

I was going to use the Cutter HS-14080p Heat sinks Passive Cooled. I'm running Co2 in the room and my temps are running at 88d avg. I also have a 1200 Mar II covering a 3x3 area in that room as well.

They're the same (or similar) to ones I found on alibaba by kingbrite.

Takes a lot of thinking to sink through my thick skull....using
HLG-240H-C1050 driver as an example.

So is it as simple as
* Constant Current Region of 119-238v = How many COBS (36v) it can run (119/36 min and 238/36 max) 3-6 cobs

* Rated Current 1050ma = How hard the COBS are driven

It does not matter if you run 3,4 or 6 COBS they will only be pushed by 1050ma?

Grow space: A portion of my closet that is about 21in x 21in x 60in (53.3cm x 53.3cm x 1.52m). With Orca grow film on the walls and on top of the carpet.

Vegetative light... Major parts list:
- Two 6500K 80 CRI COBs [Typical Foward Voltage(Vf): 34.6 each]
- Two BJB Reflector/Holders
- Two one sided thermal adhesive pads
- Two 105mm "Pin fin" heat sinks

Flowering light... Major parts List:
- Four 3500K 90 CRI COBs [Typical Foward Voltage(Vf): 34.6 each]
- Four Ideal Chip-lok holders and Ledil angelina reflector adapters
- One sided thermal adhesive pads
- Four Mechtronix heat sinks

Misc parts list for both light arrays / luminaires / chandeliers:
- Ideal Luminaire disconnects
- Self tapping, Hex head, M3x10mm screws
- Self tapping, Hex head, M4x12mm screws
- Rivets
- 18 awg solid core wire (about 8m)
- A 125 volt three prong plug
- Angled aluminum (3.175mm x 1.22m)

LED Driver for light arrays / luminaires / chandeliers: MeanWell HLG-185H C1400A driver

What Amperage are you using in these COB's?

If you have constant air circulation 5klm/sqft would work great
those COB's run at 13lm+ @ 2.1a/each your looking at about 8lm per light based off what your saying. Is my math right at this point ?

The maximum driver amperage is 1400mA. At any point in time during a grow the amperage can be as low as 700mA(.7A) or at maximum.

The particular driver, I am using, is "remote" mounted and I am using the built in potentiometer rather than what is commonly used.

If you do not already know... For MeanWell drivers that are designed for series wiring, the letter after the 1400/1050/700/350 is model type. The numbers before the final letter is the maximum amperage written as milliamps(mA). MeanWell drivers designed for parallel wiring the numbers before the model designation is the maximum amperage without a decimal point. (IE: 48A would be a driver with built in potentiometer with a maximum amperage of 4.8A)
