What Materials Make The Best Heat Sink?

Most LED heat sinks use aluminum due to its excellent heat dissipation and easy manufacturing. Copper is also used in critical applications but is much more expensive.

There are different types of heat sinks on the market, often broken down by materials (e.g., aluminum heat sinks) or shape (star heat sinks, etc.,). The type of heat sink you need is largely contingent on the build of your LED light.
