DIY LED Heatsinking Test w/ 10watt(x10) weight to watt RATIO

Check out my video; I test a fan-less 10 Watt on heatsink. Meant for x10 10watt use. Conclusion: 200g aluminum heat sink to 10 watt led will not require a fan. Also shows fanned design. Watch the video for ideas.

DIY Grams-Heatsink-to-Watt-LED RATIO Testing:

Technically speaking if it reaches 88 degrees we can go back to the future

The overall weight of a heatsink is of lesser importance than the amount of surface area of the heatsink. We have quite a large thread on DIY heatsinks, let me see if I can find it.

Yep it is nice to have a combo of weight and well-exposed surface area so the air is able to convect out from between the fins. A heavy, thick thermal path reduces the temp gradient from the heat source to the fins. So fin temp can be higher and LED temp lower. That higher fin temp makes for a more efficient transfer of the heat to the air. Passive cooling is definitely worth the trouble, especially as COB efficiency increases we can get the job done with much less heatsink.
