I have a small welding contracting company in the GTA. And I have a good line on some Aluminum that works great for heat sinks for LED builds. If anyone is looking for it I buy it in 120ft bundles that come in 12ft length. I can cut them down for you if needed. I always have extra in case I need to build something. I bet you the price is much better than metal super market. By far. I can also help you make your lights if you need help sizing drivers to strips etc.
a 4 Ft length of this section easily dissipates 108W.With only 2 degree rise over ambient very cool to touch. Will be testing with 150W shortly.

and then the smaller profile can take two strips. But I use this from my structural pieces.

Pretty much always have drivers, strips and aluminum on hand. I buy them in bulk off Digi-Key or Arrow just as you guys see in the arrow sale thread when guys update it. But I also have a contractor account with Digi-Key so I can usually negotiate an extra couple dollars off standard strip prices.
Also if anyone wants some drawings with dimensions you can use for builds I'll provide later. Below is a 600W design I am gonna test soon and make sure it's totaly good for heat etc.
