Features aluminum heat sink Made of high quantity aluminum, good thermal conductivity Aluminum Heat Sink Heatsink Module Cooler Fin Reduce the risk of LED light failure due to overheating Aluminum Heat Sink Radiator Cooler Designed to maximize its surface area in contact with the cool air Light weight and used in applications where weight is a big concern Silver heat sink Specially designed for high power household LED light or fish tank LED devices, etc Description:A heat sink is a passive heat exchanger that transfers the heat generated by an electronic device, thereby allowing regulation of the device's temperature at optimal levels. This heat sink is used with high-power LED light, where the heat dissipation ability of the component itself is insufficient to moderate its temperature.Specifications:Material: Aluminum Size: 300*140*20mm / 11.81*5.51*0.78"Fins: 19Quantity: 1Weight: 570g(approx.)Package Includes: 1 x LED Heat Sink Package List
