An LED light with heat sink is formed from a metal board with holes for mounting lens and reflective cavities inside the metal board, and within the cavities, multiple LED chips are mounted, and with a PCB board on the top of the metal board. One wire pair is connected to an LED light to form external power supply wires. Small holes on the PCB are to mount the lens and the big hole is to let the light through. The LED chips are mounted directly on metal board functioned as heat sink in electrical connection with the wire pairs makes an ultra thin, high brightness, and low cost Power LED Light. The reflective cavities may have single or multiple chips mounted inside with the chips directly mounted on the metal board within the reflective cavity.
