Just watched your YouTube video! Gives me the ok to go ahead and buy. Funny seeing some people saying it doesn’t work in some modes haha. Some notes. You are right copper has a better thermal conductivity and allows the heat to get out faster. I’m not sure why they made it raised from the aluminum that seems kind of dumb cause there won’t be any airflow there and it reduces your total area of contact. More likely something to do with manufacturing that heatsink. Second note, when reapply the thermal grease you really should remove the old stuff. When you have too much thermal grease it can actually make the thermal transfer worse. You really just want a light coat because that grease will fill in any gaps and imperfections on the surface of the metal. Too much can also cause it to ooze out more and has the potential to generate Vocs that can build up on the led and darken them over time. And if it wasn’t clear from my way too technical description, I’m an electrical engineer who works in lighting haha
