December 7, 2018 -- Emerson announced the LED version of the Appleton A-51 lighting fixture.
First introduced in 1951, the Appleton A-51 incandescent factory-seal luminaire has long been a standard for industrial lighting, providing safe illumination to workers in petrochemical processing, wastewater treatment centers, chemical plants and other areas classified as "hazardous" by the National Electrical Code where ignitable vapors, dust, moisture and corrosive environments may be present.
Because it uses the same mounting as the original A-51, the LED version transforms the traditional retrofit process to removing the legacy incandescent fixture unit and replacing it with the LED fixture unit. Appleton's standardized threads fit all A-51 LED fixtures and mounting hoods. In the event the A-51 LED requires maintenance, its "wireless" design allows the fixture unit to be threaded off the mounting hood for fast servicing or immediate exchange with a stand-by replacement.
Emerson is offering the luminaries in an output range of 1,600 to 3,200 lumens to replace incandescent fixtures up to 300 watts. They deliver bright light with color rendering for optimal visibility. The LED lamp has a lifespan of 50,000+ hours
To guard against corrosion and chemical abrasion the A-51 LED's fixture unit, mounting hoods and guards are manufactured from copper-free, die-cast aluminum, and feature Appleton's epoxy powder coat finish to assure long-term corrosion resistance. In addition, end-users can specify either porcelain reflectors for standard applications or fiberglass reinforced polyester reflectors for exceptionally severe corrosive atmospheres.
Appleton A-51 LED luminaries are suitable for wet locations, and are compliant with NEC/CEC certifications for Class I, Division 1, Groups A, B, C, D; Class II, Division, Groups F, G; Class III, and Class I, Division 1, Groups C, D; Class II, Division 1, Groups E, F, G; Class III hazardous applications.
