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: AluminumSize: 300*140*20mm / 11.81*5.51*0.78"Fins: 19Quantity: 1Weight: 570g(approx.)Package Includes:1 x LED Heat Sink
