Abstract: Described herein is a light emitting diode (LED) luminaire comprising a cylindrical plastic housing having a first open end and a second open end. At the first open end, an externally threaded formation terminating with a flange is formed to mate with an internally threaded mounting unit, and at the second open end, an internal ridge is formed with a circumferential groove at its base. Inside the cylindrical plastic housing, an aluminum heat sink is insert molded. The aluminum heat sink has a cylindrical profile matching with the internal profile of the plastic housing. The aluminum heat sink has an open end towards the first open end of the plastic housing and a closed end resting on the internal ridge at the second open end of the plastic housing. With the interior surface of the closed end of the aluminum heat sink, a printed circuit board (PCB) holder plate locks a PCB driver.
