You can veg and benefit from a higher cct-temp cobs but it's not really necessary or worth while. Unless you are planning 2 separate lights for 2 separate spaces. Most of my grows start and finish with 3500k and I'm pulling some numbers.

I've been thinking my aluminium plate may be a tad small for 200 watts..
it's 23cm x 38cm. Rectangle just not that big.
Whats the average spacing for 200 watts of cobs, the size of a mars2 if youre using an aluminium plate right haha?

So i've found some cheap aluminium parts, nice square tubes with plastic 90 degree connectors and a plate thats 30cm x 90cm only issue is the plate is only 0.5mm thick.. is that too thin?
Ive got some nice ideas i might get on paint or another program and see what i can draw up..

It may need a frame around it. Probably to flexible on its own.
It is far too flexible on its own, the square tubing is thick and perfectly rigid though, and all type of plastic joiners are available.
So i'm thinking i may frame the plate into a nice square or rectangle, just not sure what the best dimension would be after factoring my tent size and light output, 1m2 x 200w of 1212's.
Also if i may borrow your imagination for a second... Take multiple lengths of different width round aluminium tubing and slice them all up into 50mm segments. Then dip one base side of each segment into thermal adhesive then place each sized segment inside another onto the aluminium plate like a babushka doll in half haha. Do you think this could manage heat safely?
My metric conversions are pretty much crap. 1m2 os 3x3 feet or 36"x36" right? If so a square frame with 12" centers would be perfect.
12" cob 12" cob 12"
If you do 12" spacing the frame will need to be 12" plus the width of the heatsink as well.
I love DIY heatsinks but unfortunately without a degree in engineering trial and error is our only hope. I'd say go for it but leave room to expand. If it's warm to hot you could always crank up a oscillating fan nearby
3.3ft or 39".
So by 12" centres you mean a square frame made of 12" lengths? or 24" lengths with 12 being the halfway point? and im also a bit confused with the spacing.. will i need all five to light up the 3.3 ft?
I do have few small miscellaneous passive fin sinks active fin and plenty of room for oscillating fans i've planning a hybrid thermal management setup the whole time, im confident it all should add up to enough.. I don't have the funds for cob to pin at the moment.

Say the heatsink is 5" wide id make the frame 18" square with a heatsink on each corner. Doing that would leave you 13" on each side and 13" centered on each cob. I'd draw it out but I'm on the road.
Ohhh man... I've hit a few bumps on the road.. My cobs didn't rock up but i did get a refund. Fairly disappointed, i was exited about x5 1212's!
Im looking at some more, probably ordered domestically this time though.
Lumileds L2C5-35801205E1300, LUXEON COB Gen3 White CoB LED, 3500K 80CRI
Is anyone familiar with this brand? they look to be the newest gen @ 1.41 efficacy. for $20 odd each seems alright.
Another thing i had second thoughts about was my driver reading277VAC for North American use only, refer to first post for pic.
Any help appreciated! Cheers guys.
