The Edwards 117 Class Strobes provide a bright visual indication by utilizing a linear strobe tube inside a shatter resistant polycarbonate Fresnel lens. They feature a NEMA Type 4X enclosure, and are suitable for use in indoor and outdoor applications where reliable and distinctive visual indication is required. When mounted outdoors the unit should be mounted with the lens facing up. Designed for industrial, commercial, and institutional applications, the low profile 117 Class is suitable for industrial wash down applications as well as for use on tow motors and other vehicles. Edwards' strobe lights are particularly effective in high noise areas where ear protection must be worn and audible signals may not be heard or understood.
