Aluminum Heat Sink 300x140x20mm — LED Cooler for Lights & Fish Tank Fixtures, Heat Dissipation

Constructed from high-grade aluminum to deliver excellent thermal conductivity, this 300x140x20mm heat sink pulls heat away from LED assemblies to help reduce failures caused by overheating. The fin profile is optimized to maximize surface area exposed to cool air for efficient heat dissipation while remaining lightweight for applications where weight is a concern. Specifically intended for high-power household LED lighting and fish tank LED devices. Fits 8pcs 3W LEDs or 20pcs 1W LEDs.
