9X DIY COB..."The Patriot"...aka "M.O.A.coB"...aka "Make America Grow Again"

It's time to start the new project. Did some shopping at cobkits.com:

9 Luminus CXM22 Gen 3 3500K 90 CRI
9 BJB holders
3 Bourns 100K pots
9 133mm passive pin-fin heatsinks
9 Artic thermal pads
9 Angelina reflector for BJB
3 Meanwell HLG 320H-C1750B drivers

Other Vendors:
3 aluminum project boxes
8 1/8" aluminum angle iron
100 3/8" rivets aluminum
Mag polish
Polish Wheels
2"x1/8"x4' aluminum bars
Duplicolor anodized paint
Rustoleum semi-gloss paint
3 M20 waterproof connectors
3 Levitron LED glow grounded connectors
30' 16 awg 2 connector shielded wire
30' 16 awg 3 connector shielded wire
24' 16 awg stranded wire white
3/8" grommets
Heatshrink tubing
M4 machined bolts and nuts various sizes
1/16" aircraft cable coated
3/32" ferrels
3 American Flag knobs 6mm

Not positive on BJBs, but I know for certain Ideal ChipLok, Vero Poke in, and most connectors are 18-22awg ready. Hopefully that 16awg will fit into the holders connectors.

Props on the extra effort on using right angle braces to rivet to. I always just cross over.

You are totally right about the 16 awg not fitting the BJB. It's stranded so I will peel back a few and tin the correct size.

Time to start polish.

Time to degrease and anodize the frame.

Where'd you pick up that set of HeatShrink? That's really nice. So many sizes and the perfect length.

Nope Air! It's a 3x3. Here's my thinking. I wanted to build a light for a bigger tent but also be able to use it for my 3x3 right now. The 9 COBs will mean each sqft technically has its own light which is complete overkill I know. I have a potentiometer for each row so I don't even need to turn on a row or 2. Also, and let me know if I'm wrong, I'm hoping running these lights barely on will keep cost down although I'm not really that worried. I hated that my crappy burple LED light didn't provide even PAR across the whole tent and now I hope I get it.

What I really need help on is to determine what the output is without a PAR meter. I have marked the pots at 25, 50 and 75% based off of my meter. I would really appreciate the collective minds here helping me. I have 3 Strawberry Cough germinating. 2 will be in the tent in 7 gallon fabric pots and 1 will be outside in a 20 gallon fabric pot.
