Published 25 Oct 2024
Hazardous Area LED Lighting
Zone 1 & Zone 2 LED Light Fittings
When it comes to ensuring plant safety, enhancing worker comfort, and managing maintenance costs, the luminaires you select today will play a crucial role for years to come. Emersonâ„¢ presents the Linmasterâ„¢ LED Series of linear luminaires, designed specifically for rugged Zone 1, 2, 21, and 22 applications.
Please Note:Â Appletonâ„¢ ATXâ„¢ Linmasterâ„¢ LED Zone 1 Series replaces the FELED Series Luminaires & Linmasterâ„¢ LED Zone 2 Series replaces the FNLED Series Luminaires
Certified for IECEx and ATEX installations, the Linmasterâ„¢ luminaires offer a hazardous area led lighting performance that matches or surpasses that of our established FE and FN Series fluorescent luminaires, as well as the FELED and FNLED linear non-metallic luminaires. These products have long been regarded as the industry standard.
With the Linmasterâ„¢ Series, you can leverage the same footprint and mounting hardware as the FE and FN Series, providing a seamless and efficient retrofit for any existing fluorescent installations. The range of lumen outputs available ensures that you’ll find the right fit for your specific task or general-purpose application, regardless of mounting height.
For unparalleled corrosion resistance, durability, and performance, trust in the Emerson brand. Choose Appleton™ Linmaster™ Series luminaires—your reliable partner in illuminating your workspace.

The Simple Way To Light Your Way Forward
Linmasterâ„¢ Luminaires make it easy to replace existing fluorescent fixtures because they feature the same mounting dimensions and mounting accessories as original FE and FN fluorescent luminaires. Hazardous Area LED Lighting is available in light output from 2,500 to 7,000 lumens. In the rare event maintenance is needed, the cover can be quickly removed to access the internal components, while the specially designed hinged cover speeds up the process of replacing drivers, or other components.
Retrofitting Made Easy
The Linmasterâ„¢ Series includes models that provide illuminance and lighting distribution comparable to our FE Series fluorescent luminaires, with additional models that offer even more application possibilities. Choose the diffused cover option for the greatest uniformity, least amount of glare, best vertical illumination and safest photobiological rating.
The lighting simulation below compares three luminaires, each mounted at 4.5 m (15 ft) in a room with the dimensions 10m (32.8 ft) x 10m (32.8 ft) x 4.5m (15 ft).The photometric simulated colour rendered images below demonstrate the seamless transition with either luminaire.
