Abstract: Slotted heatsinks comprise a base containing a plurality of slots adapted to removably secure light emitting devices, wherein each of said slots comprises at least four cavities; and a plurality of fins adjacent to and/or on top of said slots for removing heat generated by the light emitting devices. The slots may have a t-shaped or +-shaped cross section. Opposing sidewalls may also be provided together with one or more active cooling devices and various covers for the components. Related systems and methods are also provided. When combined with a suitable light source, such devices are useful for a wide range of applications, including, for example, as aquarium or grow lights.
