The Pathfinderð 100SB Series Heavy Duty Rotating Light from Edwards Signaling ' Security Systems comes with powerful, dual sealed beam lamps that rotate 360 degrees within a high-impact polycarbonate dome. The lights are available in five lens colors: red, amber, blue, green and clear.Pathfinder's polycarbonate domes are safer and easier to clean than glass domes and allow the transmission of more light than heavily colored glass. The domes are ideal for applications that prohibit the use of glass such as required in food processing plants. The Edwards 100SB Series also features a PVC-coated base that provides for greater corrosion resistance and durability than plastic or simple-stamped metal bases. The Pathfinder's quiet belt drive makes for simplified maintenance. Wiring is routed through the 3/4 inch NPT hub on the bottom of the unit which is conduit mounted.
