Appleton Contender LED Luminaire

Feb. 14, 2019
Emerson's latest LED directly mounts to competitor's HIDs without a need for an adapter.

Raising the bar in lighting performance, operational efficiency, and employee safety, Emerson today launched the Appleton Contender LED, an extra low-profile enclosed and gasketed LED luminaire that brings energy and maintenance savings of up to 65% to challenging low clearance areas, such as walkways, catwalks, stairwells, and tunnels.


Designed specifically for retrofit applications, this cost-effective solution mounts directly to the hood of a competitor's High-Intensity Discharge (HID) hazardous location luminaire without an adapter, saving time and labor costs.


Oil & Gas facilities, chemical processors, and other hazardous locations place critical demands on luminaries, especially when it comes to extreme temperature ranges and long service lives. The Appleton Contender LED provides rated illumination through its full ambient operating temperature range of -40 to +149°F to make sure facilities are safely lit in arctic cold or when the going gets hot. In addition, it features a rated L70 lifetime of 100,000+ hours adding value while minimizing maintenance requirements.


To withstand particularly harsh areas the construction includes:

  • a proprietary epoxy powder coat finish for unmatched corrosion resistance
  • a rugged IP68 watertight hub to ensure water in the conduit is kept out of the luminaire, heavy industrial-grade gaskets
  • high vibration and shock resistance
  • plus a robust 6KV surge suppression circuit to protect against damaging transients.

With three-lumen output options and four interchangeable and field-replaceable globes options, this luminaire delivers the lighting equivalent of 70 to 175 W HID luminaires to provide a fully customized solution.


To ensure safe operation in areas where flammable gases or vapors may be present, the Appleton Contender LED is engineered to meet or exceed industry standards to assure workers in places such as offshore rigs, petrochemical, and chemical processing plants, water treatment plants, and grain elevators can work productively and comfortably. It is NEC/CEC certified for hazardous locations rated Class I, Division 2 and Class I, Zone 2, Class II, Division 1 and 2, Zone 21 and 22, and Class III, as well as NEMA Type 3R, 4, and 4X wet locations and is IP 66/67 and ABS certified.
