Abstract

A light system comprising an elongated housing; at least one LED light disposed inside of the housing. There can also be at least one lens disposed adjacent to the LED light. In addition, there can also be at least one reflector disposed in the housing, wherein the reflector has a first reflector section disposed adjacent to the LED light and a second reflector section coupled to the first section, and disposed at a distal end opposite the LED light. The first reflector section being substantially round in shape and said second reflector section being substantially round in shape.
