Appleton A-51 LED luminaires by Emerson are ideal for low-height installations in industrial plants where safe clearance is critical. The streamlined design of the luminaires ensures needed headroom while achieving energy-efficient, reliable illumination in demanding environments.

The units are NEC/CEC compliant for areas classified as Class I, Division 1, Group C and D and they deliver the efficiency and longevity of LED technology to hazardous locations. They can install directly into legacy A-51 incandescent mounting hoods with no rewiring required, reducing retrofit time, labor costs, and operational downtime. Plug-and-play architecture enables the modernization of lighting infrastructure without the expense and disruption of a complete system replacement. Appleton A-51 LED luminaires are available in models equivalent to 100-300W incandescent and HID lamps and fulfill the need for luminous output up to 3,200 lumens while consuming significantly less power. The Color Rendering Index (CRI) is over 80 for accurate color representation.
