S Series LED Heatsinks Ohmite S Series LED Heatsinks are low cost and easy assembly heat sinks for “Star” LED packages supplied by Cree, Lumileds, Osram and others. This simple heat sink can hold LED modules and can be mounted simply with some thread forming screws. The heat sink has two types of surface finish and can be used in either natural (free) or forced convection cooling applications.
