New Heatsink Concept

We will be waiting here with fistfuls of hundred dollar bills ready to throw at you!

They have Mechatronix modules too....very nice

 

[Humanrob]

Is there a U.S. distributor in place, or would us Yanks be shipping overseas?

 

[bassman999]

These look good, and am also interested in Tj numbers at different current levels

 

[alesh]

Yes these are good to 80 watt, passive, so no fans, which I am a big fan of, scuse the pun

What does 'good to 80 watt' mean? It won't fry the LEDs? Or will they be cool?

 

[sethimus]

negotiating prices now, one off is bit ugly, but if I can get 200 pcs sorted, would be approx USD32.00

would these already come with holes for 3590 holder and reflector holder?

Didn't we see these in September? Or Feb 2015? Glacial Light make a shit ton of cool stuff but it seems so hard to find. Maybe GG should become a distributor for them ?

Hi Mark,

What's the material of the heat sink?

6063 AL
Cheers

[welight]

hi mark,what is the weight of the sink pleas?(sink only)

1kg
Cheers

It means they have a thermal Capacity to dissipate 80 watts, so a 3590 at 50%+ eff would be less than 40 watts, so the cooler has twice the capacity than required

we can have them delivered predrilled for the ideal holder

Thermal Resistance of the cooler is 0.5942 DegC/W, surface area is 528047mm2

I would be willing to buy these if you can source them. Pre-drilled would be nice but I could do it myself if necessary. Anodized would also be nice, but also not absolutely necessary

anodized heatsinks perform significantly better than their non-anodized counterparts.

I agree for passive cooled anodized helps.
My old test. Anodized heatsinks may underperform compared to non-anodized heatsinks under active cooling.

True, but enough is enough. Those sinks can handle up to 14 watts of heat and keep temps in the low 40s at room temp. I would be needing them to dissipate less than 10 watts of heat. Anodizing would be icing on the cake.

Mmmmmaybe but really that whole system is about the mounts and if you really think about it you could knock out a few of those at Home Depot but if you got the scratch and no time, why not buy the Glacials. I like them for a big room, stadium lighting especially.

And that also allows a builder to use graphite based TIM which means you don't have to worry about any mess, (no icing! ), or reapplying your paste though I'm assuming no one's lost a COB due to old thermal paste drying up so for the DIY crew I guess it's not that much of a plus.
