8020 as a heatsink for a DIY light

I would like to know if 80/20 make a good heatsink (ie https://8020.net/1547.html )? Since extruded aluminum is about the same price per inch as a heatsink from heatsink usa.

Heatsink USA product is extruded aluminum.
It all comes down to surface area.

Not to be a picky bastard but mass and specific heat might have something to do with how well a heatsink performs... The 8020 looks to have a significant amount of surface area, not the ideal thin fins that traditional heatsinks have but maybe enough mass to overcome this?

yes it will work. PLC has talked about a light coming out that uses them. not out yet on his website.

thats the one u'd want i believe. as far as how much heat they can dissipate i haven't seen anyone on here using them yet, idk. probably pretty damn similar to a heatsink profile of the same size while being way easier to work with. i assume thats why greengenes is doin it.

edit. of course the one u linked would work too i just think the square might be easier to mount and maybe more surface area

sure about that? he talked about a new designed heatsink in his last video.

no not sure at all. he mentioned something about using 80/20 or 2020 as a heatsink and i know on his site it says custom extrusions coming soon. but as far as what hes actually going to do, no i have no idea.

either way 80/20 1003 is the part i'd use and it would work great as a strip heatsink.

For strips, take whatever money you were going to spend on heatsinks and put that into more strips. At lower current you wont need them and you get more light.
