A light emitting diode (LED) array with beam directors outputting a high-intensity collimated beam. The LED array is constructed from a substrate component on which the LEDs and necessary electronics are disposed and a director attachment having a plurality of beam directors. The beam directors have a unique structure that is designed to shape the light beam into a collimated form. The LEDs are arranged in a pattern on the substrate, and the beam directors are arranged within the director attachment to coincide with the LEDs. The substrate and the director attachment may be manufactured and processed as separate components; they are then affixed together for operation.
