VERO 29 SE For a 10X15

Hello all. First timer here. Just wanted to post my plan for my lighting setup and get some feedback from the community.

Parts:
BXRC-27E10K0-C-73-SE‎ (spectrum of 2700k for Flower)- X 10 of them
BXRC-30E10K0-C-73-SE‎ (spectrum 3000k for flower) - X 10 of them
BXRC-50C10K1-C-74-SE‎ ‎ (spectrum 5000k for Veg) - X 20 of them
(The Driver which can run up to 10 at a time)
HVGC-650-M-AB‎ - X 2 of them for now (will get 2 more If needed).

Wiring:
I'm planning on running all the COB's on the lowest (and most efficient amperage of 0.855 amps) so that a single driver can handle 10. It would be 5 cobs in parallel followed by 5 more (or two in series).

4.275 Amps = 0.855 Amps x 5
132.4 Volts = 66.2 Volts x 2
566 Watts = 56.6 Watts x 10

PPFD:
I wanted to use 10 Vero 29' SE's for my (10x15 foot) grow but based on this [https://www.waveformlighting.com/horticulture/convert-lux-to-ppfd-online-calculator] calculator it seems I need at least 20 (all the COB's I have for each phase of growth).

I was conservative and assumed each COB would only produce 15,000 lumens that comes out to a lux to 21527.82 as per this calculator [https://www.rapidtables.com/calc/light/lumen-to-lux-calculator.html]

Then using this calculator [https://www.waveformlighting.com/horticulture/convert-lux-to-ppfd-online-calculator] im told I get around
371 umol/s/m2 for 6500K (im applying this to my 5000K COB's) & 409.62 umol/s/m2 for 3000k (my mix of COB's @ 2700k and 3000k).

Does this all make sense?

No it doesnt make sense to me im afraid. I dont know where you get 15000lum per cob from on that low wattage. The output is relative to the wattage and at around 55-60w it wont output 15000lum. Normally, calculate 30-35w per square foot: your 10x15 needs around 4500w. With your drivers you have about a third of that covered.

The rest of the calculations seems ok but based on wrong input numbers. But even so, they show you that youre severly underpowered for the space.

Hey! thanks for replying. I am getting my lumens from the bridgelux data sheet attached to the post.

Lets take BXRC-27E10K0-C-7x-SE for example. On page 13 of the data sheet it shows lumens for different drive currents.

One of the options is a drive current of 855mA, 56.6W, and 66.2V outputting 10,759 l'm (about 5000 less than my initial estimate which I now see is wrong). But still pretty decent.

I'm thinking that as long as my drivers can power 10 COB's at a time Ill just go for a smaller area, because this is all the lights I can afford at the moment. Maybe I'll up it later.

I think im going to reduce my space to 50 square feet for now. Until I can afford more lights.
