LED heat sinks transfer heat away from LEDs, helping prevent reduced light output, color shifts and shortened lifespan. An undersized or missing heat sink is one of the most common issues we see in LED lighting applications. Explore anodized extruded linear heat sinks, LED and light engine housings, aluminum stock and small finned heat sinks below. Learn more about why LEDs need a heat sink.

General Information on LED Heatsinks
Do I need a heatsink?
What material provides the best cooling?
In general, if you are running LEDs at or over 350mA, then a heatsink is required.
Setting aside all factors besides thermal resistance, the best metal for conducting heat, from highest to lowest are: silver, copper, gold and aluminum. Copper and Aluminum are the most commonly used materials for heatsinks, however copper is more expensive, heavier and melts at a higher temperature, making Aluminum the most used material for LED heatsinks.
How much heatsink do I need?
Is there an alternative to heatsink cooling?
Good question to ask - excess heat will degrade your LED and significantly lower light output. In general terms, we recommend a conservative 3-square inches of heatsink surface area per watt; a single high-power LED driven around 350mA is generally around 1-watt.
Often, the design of your LED application restricts the size of a heatsink, causing the heatsink to be inadequate for complete cooling. Other ways to help cool your LED can be active convection or forced air. Forced air can significantly improve cooling, in some applications active cooling can account for 40-percent of the heat dissipation. Many LED bike light applications under-size their heatsinks because of the natural forced air cooling from riding. Under water applications is another case where a heatsink can be under-sized, as typically the water temperature is low enough to act as one large heatsink.
