The Edwards 125 Class Incandescent beacons are UL and cUL listed signaling devices, available in two versions, Flashing and Steady‑On. Both versions feature a corrosion resistant Type 4X enclosure and can be panel or conduit mounted. The base is manufactured from a 33% glass filled nylon, providing high resistance to heat and high chemical resistivity. The lens is made of shatter resistant polycarbonate. Both the Flashing and Steady Burning beacons are available with either a black or gray base, and amber, blue, clear, green or red lens.
