The Edwards 125 class XBR XTRA-BRITETM led beacons are UL and cUL listed dual mode signaling devices, available in two versions, steady-on/flashing (125XBRM) and steady-on/Lightburst (125XBRZ). 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 resistance polycarbonate. Both the steady-on/flashing led and steady-on/Lightburst led beacons are available with either a black or gray base, and amber, blue, green, red or white lens.
