Grizz's 300 gal 8'er / LED Heat sink build / Opinions on LED lay out needed

[lastlight]

ok that's hardcore! so do you need to lay anything down as far as a paste etc to maintain ideal heat transfer between fin and plate?

No with aluminum the heat will transfer evenly on its own as it is a very soft alloy and a great for dispersing heat.

Do you have plans to paint it somehow and does doing that reduce it's ability to cool in any sig way?

Thing looks awesome. What a beast!

You should make a DIY lumenarc style mh reflector with an aluminum shell with fins on the top (for me)

Have you worked with thermal glue before? I used it on my LED build - it's designed to transfer heat, even if you screw the LED starts onto the heat sink directly, you should put some thermal glue for maximum heat transfer.

Looks great!

Looks Great Greg! Did you make the Heat sinks too??

Looking good bro, Cant wait to see the parts all come together
I think if i go this route I would rather brush it then cover it anyways..... Always have a soft spot for brushed alum

Very nice!!!
I think heatsink # 16 is crooked!!

lol
teasin!!! You should be building these for Modular to market!!!

This confirms my theory that you are actually building a new batman call sign haha

I was going to go with the thermal glue but it would get cooked when I welded it all together. I think there is a product like silver solder that is very thin, heat it up & pour it in & it will seal everything together.

I was also thinking of going with brushed.

Martin and I have been working together to build these he has been great to deal with. I think these would be to expensive to build for market compared to extruded heat sinks. I had the plate left over from a project and just had to buy the 1/8" x 1" flat bar.

Im down for that, always like to build things for other peoples set-ups
