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 dissipation of the heatsink above 3W.The threaded mounting holes and M2 screws make it easy to quickly install a high-power LED.To improve heat conduction, you can apply thermal compound or heat-conducting paste between the surface of the LED and heat sink.Contents * 1x 3W aluminum LED heat sink Specifications * Aluminum heat sink * Suitable for M2 screws * Dimensions: 36mm (1.418") diameter x 22mm (0.866") high https://elecena.pl/product/27745032/opencircuit-3w-led-aluminum-heatsink 2025-01-23 https://elecena.pl/product/27745032/opencircuit-3w-led-aluminum-heatsink 2025-10-11 https://elecena.pl/product/27745032/opencircuit-3w-led-aluminum-heatsink 2025-10-12 https://elecena.pl/product/27745032/opencircuit-3w-led-aluminum-heatsink 2026-02-21 https://elecena.pl/product/27745032/opencircuit-3w-led-aluminum-heatsink 2026-04-12 https://elecena.pl/product/27745032/opencircuit-3w-led-aluminum-heatsink 2026-04-28 https://elecena.pl/product/27745032/opencircuit-3w-led-aluminum-heatsink 2026-08-04
