This aluminum heatsink is suitable for most 1W to 3W LEDs already mounted on star-shaped heatsinks. This heatsink can passively dissipate up to 3W of heat. An external fan can increase the heat sink's heat dissipation beyond 3W.
The threaded mounting holes and the included M2 screws make it easy to quickly install a high-power LED.
To improve the heat conduction you can apply thermal compound or heat conductive paste between the surface of the LED and heatsink.
