[2Stoned2Care]

waaaait, i gotta make certain.

edit: alright i was right.. phew
you can also use the 2033 ones for citizen 048 cobs

Oh the 2033 are the ones @BigSm0 uses so i will get those instead

I'm glad I could help.

I just wish they also made ones for the vero 29s.. but I've settled on the gen7 v18 ones. Currently I'm looking for a good local-ish heatsink source. Best so far is cooliance but they're a tad far away.
I'm also perusing this little catalogue just to see what's out there: http://bender-wirth.com/katalog/scetch/B&W_Bridgelux.pdf

are you trying to get the passive pin fin heatsinks because i cant find them anywhere in the uk or eu ?

 

[Rapha El]

Yeah i could get some profile ones but that's not how i plan to build it. I wanna build a 4cob array first then maybe extend to 8 down the road to get as close to 100k lux as possible.
local i've only found small ones of 80x70mm max. Now these gysu also have an office in germany.. http://www.cooliance.com/NA/Products/LED-Coolers/Bridgelux/LED-Coolers-For-Bridgelux-VER018G7.php So my hope is they also have some stock there.

Hang on I just noticed.. 80x70 should be just enough..

time to verify

yeop.. damn how could i have overlooked that.

80x50.. it says it's capable of handling 28w max.. but from all the comparable products i've looked at that seems rather low?! can i get a sanity check on that?

@BigSm0 can help you with that bro

Well I don't read Russian lol but I think it's actually sized properly. The colliance i have a few of are 100mmX70mm with a 10mm base. eBay ones are much smaller. They say mine are rated for 50w but I have seen temps up to 144f

If your on a pc and not on a phone like I am your best bet is to check components Distributers. Type passive fin in search and you can scroll through all them. To make something work that's not intended to you really need to cross reference heatsinks that do work.

Wish i could just reach in there and nick 4 of those lol.if i wanted 10 of those to the uk it would cost me 34 dollars shipping hahahahaha

I'd give them to you if I could. I paid .93 each.

I only needed 36 to match my drivers but they were delayed so long I just took the whole bag lol. I didn't like paying 2.50 each knowing .93 was my price after 2 people already made money on them and shipped them twice.
