Sorry i tried googling but im clueless as to what they are used for or what the benefit is. What change would it make to how the kit is wired currently?

You might find this enlightening in the future. Digital calipers and spring loaded punch are a powerful combo. Scribe with calipers, punch, drill a pilot hole slow and steady and you might be surprised.

I dont understand why you didn't just drill one hole, then screw your heatsink in through that hole, then lift the heatsink just above the aluminum L bar, pivoting on that screw, so you could see where the center would be for the second hole, mark a line, then use an auto center punch to get a start, remove the heatsink, and drill your second hole?

bahahahahah lol
hey what up guys
got the lights up and running and i am stoked!
they runpretty cool. lowered the temps in the cab from like 27 to 25c. put a thermometer on top of the pins and have been monitoring them pretty anally; never been warmer than 36c, typically like 33
so i dont know about the whole insert photo thing but you get the picture. stoked to build a smaller unit for the veg cab too, switch out those lame burple bulbs
wanna say thanx again to growmau5 and you other guys on here for sharing your knowledge with the community. good kharma coming your way for sure

Not to be a nit-picker but I don't get the logic of the translucent Angelinas. They're clearly designed to give some soft side light through the sides of the reflector. While I can see the benefit in a normal lighting situation it seems contrary to what would be appropriate for a grow light. I know it says such and such an efficiency but anyone can see the light coming through the sides. They have opaque metallic ones so what's the attraction of these translucent units, price?
Look at this baby for instance. That's premium. BTW here's a cool page where you can see various beam angles by putting the cursor over the image. 60 degrees looks pretty good for a COB. 90 is actually overspread looking to me.

Agreed^
While I think it has to be assessed on a case by case basis, I think for the average DIYer, purchasing reflectors is not beneficial. If I was to add 4 reflectors to my DIY Vero 29 bar, it would increase my price by over 20%. I don't think I'd see that kind of return in production, but would like to hear other peoples thoughts.

Nothing wrong with nitpicking, but the Angelina reflectors work great, and 90 degrees is a real sweet spot for reflectors.
Here is some actual data from @robincnn in this thread https://www.rollitup.org/t/lens-and-reflector-optics-for-cob.893660/
top row for 12 inches, open space
middle 18 inches, open space
last 18 inches, reflective 2x2.5 space
