Magnalight by Larson Electronics offers its EXP-EMG-EXT-12W-2L explosion proof emergency light with an exit sign that provides 90 minutes of light in the event of power failures. The system is Class 1 Division 1, Class 2 Division 1 & 2 approved and provides fail safe operation in industrial environments. This combination emergency light and exit sign provides a highly visible light signal that automatically switches to emergency battery backup operation once normal power is abnormally cut. The single 6 watt LED lamp and an LED illuminated exit sign require less current than incandescent lamps. The housing is constructed of copper free aluminum and powder coated for resistance to corrosion.
