Need advice on lighting and spacing of RDWC

[snap360]

I'm getting lost and need your help. I’m planning on setting up a 6 bucket RDWC system have a few questions on lighting and spacing of each bucket.

Environment
Grow will be in basement. Ceiling is 6 feet tall. Room temperature hovers between 63-70 Fahrenheit. Setup will be RDWC system using Hydroton and GH nutes.

Intentions
Trying to avoid buying on Amazon pre-made COBs but have NO clue on lights. Spent many hours researching only to be even more lost. I come to the realization that I should just stick to the Vero 29 B/C 3500K 80 CRI cobs. I was thinking of putting each COB over each bucket container. 6 x COBs. Is this too little lighting? Should I go with 9 COB leds instead?

Requirements
- Ability to adjust height of light per bucket container. Don't think I need dimmers as I plan on under driving the lights.
- Future expansion if I decide to add more buckets.

Questions
- Is the spacing appropriate for scrogging in the RDWC?
- If I stick with Vero 29 COBs, what parts do I need? Super clueless. I know that ideally I want passive drivers so under driven. Is there such a thing as 60W Vero 29 that is passive cooling? What parts/drivers do I need to accomplish that? I am wanting reflector lens too.
- How do you suggest I hang the lighting considering I have 6 ft. ceiling?

build a board and mount the cobs in sets of 6 or 5, those cobs only generate 12,596 Lumens each,
your average 600w hid will generate 95,000 lumens

i doubt very much 1x cob will be enough per plant, maybe a quad board

Just to add my 2 pence worth

Lumens is the total amount of light emitted from a source. In the case of HID is is emitted almost equally in all directions along the bulb length

Cobs direct the light into a beam on to the target, and the lumens per sq meter ( lux ) will be higher.

Its much better to know PAR since plants thrive on a wider spectrum than the human (lumen) range.

What budget do you have?

Have you considered medium power leds in the form of quantum boards or strips? The price is now is far too good to overlook...

Agree fully, all my research said the same that PAR was more important
