    Designed for Easy LED Lighting Retrofits

    First introduced in 1951, the incandescent Appleton A-51 became an established lighting solution for industrial and hazardous-area environments. The LED version builds on this design, making it easier for operators to upgrade existing installations.

    The Appleton A-51 LED fits the same mounting hoods as traditional incandescent A-51 luminaires. This allows users to replace the existing fixture unit without rewiring the mounting arrangement, helping simplify installation and reduce retrofit work.

    The fixture also features standardised threads that fit compatible A-51 mounting hoods. For maintenance, operators can unscrew the fixture unit from the mounting hood for servicing or replacement with a standby unit.

    Key Benefits of the Appleton A-51 LED

    • Reduced energy consumption: LED technology can reduce energy costs by up to 80% compared with the incandescent model.
    • Simplified retrofits: Compatible mounting hoods help make upgrades easier in existing installations.
    • Long LED service life: The stated LED lifespan exceeds 50,000 hours.
    • Lower maintenance requirements: The replaceable fixture unit supports convenient servicing and exchange.
    • Multiple mounting options: Choose from pendant, ceiling and bracket mounting arrangements.
    • Corrosion resistance: Copper-free die-cast aluminium construction and an epoxy powder-coat finish help protect the fixture in demanding environments.
    • High-quality illumination: The LED design provides a light pattern and spread similar to the original incandescent A-51.

    Applications for Hazardous-Area Lighting

    The Appleton A-51 LED is designed for industrial environments where hazardous materials, moisture or corrosive conditions may affect lighting equipment.

    Typical applications include:

    • Chemical and petrochemical plants
    • Oil and gas facilities
    • Wastewater treatment plants
    • Heavy industrial and process facilities
    • Hazardous areas where ignitable vapours or combustible dust may be present
    • Wet industrial locations

    Always check the specific fixture model, certification and hazardous-area classification against the requirements of your installation before selecting lighting equipment.
