Arguably, heat management is one of the most important factors in extending the life expectancy of an LED light. So what is it? It’s the technology of preventing and reducing the build-up of heat in LED chips, which are sensitive to prolonged heat exposure. Management is mainly accomplished by the design and composition of the light’s heat sink (the ridged metal fixture attached to the back of the LED). Aluminium heat sinks are by far the best, as aluminium is a great thermal conductor. Additionally, our aluminium dishes are deep, not shallow, adding more surface and material for heat dissipation than other models. This helps us extend the life span of our LEDs for you.
