Heatsink for multiple LEDs ?

I have been boards that hold multiple LED's, but they are never "generic" - they are always designed for a specific LED (of family, if they use the same footprint). What size and shape do you need (round, square, rectangular)? What specific LED you are trying to use?
Should be same footprint as luxeon 1W LEDs, and this one: http://dealextreme.com/details.dx/sku.13612
It is just some ebay-LEDs, so sadly there's no datasheet.

Please don't take this the wrong way, as I don't know yet what you are trying to build/do, but why use LED's that are 3-4 years old in terms of power vs. output? Using the Cree XR-E or the new XP-G's would give you LOTs more output from the same low voltage/current as a 1W Luxeon.
Because this project does not need LEDs with that high efficiency - they would be too expensive. Im not saying that i use luxeon LEDs, only that the footprint is about the same.
But.. This thread is not intended to discuss what LEDs to use, but where to get a heat conducting PCB for them.

only idea is Cutter's 5 or 7-up mcpcb's. They offer serial / parralelle connection options. perhaps you could rip off the excess slots and turn it into a straight line configuration?
iirc there's a 6 in line board for Rebel 100's, that'd be cheap and easy. not sure location, try luxeonstar.com

Ill give it a shot - thx
EDIT: Cant seem to find any that can hold several in a straight linie. Maby i should just go with 6x single boards?

Did you see the price on those? $140+ !!

woah, to be honest I didn't check pricing at all. I knew there were straight strips there and I found them and posted the link ...
Yah, but those come loaded already. If you don't need the best efficiency I would just look at some of the led strips from asian dealers using SMD leds, the 5050 are pretty bright.
There are some pretty cool heatsinks here both linear and round. And really good prices.
*edit*
I am not sure you would be able to use cree with them though, probably only round package.

Look at these for 20 and 23 bucks. Again, I dunno if these will serve your needs or not, but could save some work.

That company ships out of Turkey, I emailed them awhile back when I posted about some of there drivers, but I haven't ordered from them yet. I plan on it though.

Aww that MCPCB with 6 LEDs looks great - but.. i need it without the LEDs. I already have 52x 1W LEDs waiting
2 x Aluminum Base Board for 18pcs 1W/3W LEDs - 96x38x1.6cm
5 x Aluminum Base Board for 9pcs 1W/3W LEDs - 80x1.6cm
10 x Aluminum Base Board for 3pcs 1W/3W LEDs - 35x1.6cm
10 x Aluminum Base Board for 5pcs 1W/3W LEDs - 50x1.6cm
Should get me started !

You realize, don't you, that the payback for all the help is that you should post pictures and description of your project.

Yep, i will do that when i can see an end to the project
