Four LED Light Distribution Patterns Maximize Fixture Spacing and Improve Uniformity

Emerson has announced an upgrade of its Appleton Mercmaster LED series. Building upon legacy features, the Mercmaster Generation 3 LED offers four light distribution patterns, seven lumen output levels, expanded color temperature options and a choice of replaceable globes and mounts.

The enclosed and gasketed luminaires withstand industrial environments without compromising reliability. Delivering a compartmentalized design for minimizing the effects of elevated ambient temperatures, its single-piece driver housing features separate sections for the terminal block and driver to ensure thermal efficiency. Additionally, the silicone rubber gaskets seal out moisture, dirt and dust, staying flexible and withstanding high temperatures, while the Extra-High Hinge provides protection against accidental ballast housing disengagement during installation or maintenance. Its design is rated for Class I, Division 2 and Class II hazardous locations, marine and wet locations, and is also certified for ATEX/IECEx Zone 2 – 21 and 22 to provide a lighting solution for all harsh industrial and hazardous illumination needs.

Suggested applications are oil refineries, petrochemical facilities, chemical plants, power generation plants, and other areas where flammable gases and vapors may be present. Non-hazardous models of the Appleton Mercmaster Generation 3 LED are also available and can be used in locations where severe weather conditions, excessive moisture, dirt, dust, corrosive atmosphere or where high ambient temperatures are encountered.

Versatility

Thanks to the versatility of the Mercmaster Generation 3 LED, hard to illuminate areas such as walkways, wide passageways or decks, no longer need to suffer from poor light levels and uneven uniformity.

For example, the its secondary optics are engineered to create four types of light distribution patterns (Type I, Type III, Type V, or Type V Wide). Designed to meet customer’s needs, these light distribution patterns maximize fixture spacing, while minimizing the number of total fixtures needed and improving uniformity. As a result, overall project cost is reduced and employee safety is improved. Light distribution pattern versatility is important in greenfield and brownfield projects demanding luminaire flexibility due to tough to illuminate spaces and the variety of lighting needs.

In addition, the Mercmaster Generation 3 LED offers four replaceable globe options of Clear Polycarbonate, Diffused Polycarbonate, Clear Glass, and Prismatic Glass to provide application versatility. These globes help to diffuse glare, reduce hot spots, soften illumination, and increase fixture adaptability.

Seven lumen outputs levels, ranging from 3,500 to 17,500 Lumens (HID Equivalences of 70W to 600W), allow for mounting height and illumination level flexibility. By providing a selection of lumen levels, the Mercmaster Generation 3 LED helps engineers achieve precise foot-candle levels to meet target illumination levels. Expanded color temperature options of warm 3000K, neutral 4000K, and cool 5000K CCT assure the preferred color of light for any working environment.

A variety of mounting hoods offers the convenience to hang luminaries how and where lighting is needed most. With the Mercmaster Generation 3 LED’s six choices of mounting hoods engineers no longer have to compromise on fixture placement.

Smart Retrofit for HIDs

Retrofitting HIDs with the Mercmaster Generation 3 LED luminaires ensures maintenance and energy cost-savings, and can utilize competitor mounting adapters. With a service life of over 100,000 hours and a virtual maintenance-free design the luminaires are an ideal retrofit lighting solution. LED solutions deliver energy savings of up to 70 percent when compared to HID alternatives.
