Abstract: An improved lighting device includes a tower body, a pair of parallel PCBs attached to the tower body, a connector and a set of wires connecting the connector and the PCBs. The wires are wrapped inside a RF shielding and disposed inside a supply cable. Each PCB includes two arrays of LEDs. Each array of LEDs includes three LEDs. A set of omni-directional heat sinks are attached to the base of the tower body. Each sink includes a set of tinned stranded copper ropes. The copper ropes each have a free end. The lighting device further includes a plug metal retention nut attached to the connector, a ratcheting inner collar attached to the tower body, and a mounting collar. The mounting collar has tabs, a ratchet mechanism having a series of troughs spaced by approximately one millimeter, and two guidance grooves. The mounting collar is couple with the ratcheting inner collar.
