Perfect thats awesome thank you!! I lied though oneeee last question lol...heat sink wise with the chips being so small do you think i can get away with a passive heatsink? Is an active one much more work to wire in? I feel like i just grasped the driver am i gonna confuse my self further trying to wire in a cpu fan on the heat sinks ? Was thinking of doing 5 cobs on 3 of these with no fan https://www.amazon.ca/a14111400ux0256-Aluminum-Radiator-Heatsink-150x69x37mm/dp/B00VG6WPKK/ref=mp_s_a_1_27?keywords=heatsink&qid=1584349502&sr=8-27 you think that would suffice ?

If I were you, I'd just go on the cheap route and use 2 aluminum baking sheets, biggest and thickest ones you can possibly find, and use it to mount your 15 COBs each. Veros are great cause they don't need holders to mount them and you can use their molex pico connector, solder, or poke the wires right in to power them. I'd just use 2 part thermal adhesive over screwing all of them down or using tape since they have such little surface area. Mount on the inside of baking sheet and hang it upside down. It's like a ready made reflector edge. Haha

It would seem like the COB spacing would be too close or am I missing something?

Ya that sink he linked won't work. It's only 6" long. Far too small. Got some tall fins though, but not enough surface area.

Dude!!! That baking tray !! Will that actually work?!?! Cause if so im totally down to do that!! The cobs are only about an inch total diameter so could spread 15 pretty good on that particular tray or get even a bigger one if those seriously work lol regarding the connections those picos is it they just clip into 1 then clip into the next ? or clip into 1 then solder to the next? I honestly didnt even notice you could slide in like a solderless cob holder ill have yo check that out cause if i can avoid soldering and still have a strong safe connection even better Thank you again guys for the replies

These were the only picos i saw

Just use the poke in connections. You'll just strip the wire about 3/8" and stick it right in to the hole. That way it's easy to run them all together in series just connecting a wire between each cob.
As for the spacing on the cobs, you'll wanna space them closer together slightly as you come out to the edges.
I'll draw something up and come back and post it for you.

Yup those are the right ones but I'd get the longest length wire leads they offer in 18" just to be safe. Always better to have extra length if you do wanna use these, they do make for pretty clean ass connections. But so do the poke ins which don't require anything extra.
Dude!! You rock!! Thank you sooo much!! Totally going with baking sheet you think thats all ill need? No extra heat sinks or fans on top? And totally didnt even notice they had the poke ins that just made life much easier....this is gonna rock!! I should detail the build on here interms of wiring just 18 gauge solid core or braded?

That baking sheet is plenty for 100w each one. Good size too for a light. And as for the wire, solid core all the way.

Color coding your wire makes things a lot easier to visualize and work with. Just as a heads up. Not needed, but a 4 pack color, maybe green white black and red if you can find something like that or close to it, would be best.

just have it something like this. spa e the cobs closer together at the edges. I may be a bit overkill on the drawing but something like that. just measure the 11" to the center and draw with a pencil a line across so you have the center line. Start by mounting the 3 middle cobs on that line. Then just do some maths to find out what would space best.

That baking sheet I linked, so far, is the biggest one I can find at 16"x 22". So if you DO find a bigger one make sure it's as thick or thicker gauge aluminum as the other one. But the one I linked is definitely a good way to go.
Awesome thank you very much again ive ordered box of 6 color 18g solid core wire ip68 power connectors slide on solder connectors that all you need to do ia apply heat..my 2 baking trays!! Lol grabbed those exact ones friday im gonn order my 2 drivers remaining cobs and some thermal adhesive

What color temp you gonna get for these last 6 vero10's?
