Upgrading legacy incandescent and HPS luminaires to LED lighting in Class I, Division 2 hazardous locations is a challenge for facility managers who must balance long-term energy savings versus the expense of retrofitting the area with new explosion-proof fixtures.

Emerson has answered that challenge with its new Appleton™ Retromaster™ Series of LED luminaires, the fastest, most cost-effective upgrade path to LED lighting for hazardous locations. Requiring no time-consuming rewiring or cutting of conduit, Retromaster luminaires typically take only a few minutes to install onto an existing mounting hood, dramatically reducing labor and material expenses.

For decades, industrial facilities have relied on Appleton “jelly jar” style incandescent and HPS light fixtures to safely illuminate their C1D2 locations. That’s why Emerson designed Retromaster luminaires to be directly compatible with the installed base of jelly jars, including V-51™ incandescent luminaires, Appleton Stylmaster™ incandescent luminaires, Appleton Stylmaster-C incandescent luminaires (Canada), Appleton V incandescent luminaires (Canada), and Appleton Mercmaster™ Jr. HPS luminaires, as well as Killark™ V Series incandescent luminaires, while maintaining the original fixture’s certification. Colored polycarbonate globes and stainless-steel wire guards can be ordered to make a new Retromaster luminaire indistinguishable from the fixture it is replacing.

Retrofit LED luminaires are available in an output range from 1000 to 5000 lumens, and each of the four models comprising the Retromaster Series offer the unique versatility of selectable dual lumen outputs, ensuring that the illumination level of the new LED fixture is identical to the one being replaced — a first for hazardous location rated lighting. Once installed, the Retromaster requires only 7 to 38 Watts to create the same level of illumination as an incandescent drawing 60 to 300 Watts, representing a huge improvement in energy efficiency.
