Emerson launches new LED luminaire series for hazardous environments

Emerson has launched the Appleton RNLED and RELED Series, two new lines of recessed and surface-mount LED luminaires suited for hazardous and corrosive industrial environments including offshore rigs, chemical and petrochemical plants

Certified to ATEX and IECEx hazardous location standards, Appleton RNLED and RELED Series luminaires feature solid-state LED technology to ensure a longer service life, instant-on directional illumination, and dramatically lower energy and maintenance costs.

Highly versatile and configurable, the luminaires are offered in three distinct platform geometries covering the broadest range of ceiling configurations and lighting requirements with lumen outputs from 1,508 to 7,789 lumens and four colour temperatures (5000K, 4000K, 3000K, and 2200K). Emergency battery backup options are available. Also provided is 0–10V continuous dimming capability for integration with Appleton Group Lighting Controls infrastructure.

Appleton RELED luminaires are dual-certified for Gas Groups in ATEX/IECEx Zone 1 and Zone 2, and Dust Groups in Zone 21 and Zone 22, making it the specification choice for primary hazardous zones where high ignition-risk classification is mandatory. Appleton RNLED luminaires are certified for Zone 2, Zone 21 and Zone 22 applications, delivering ATEX/IECEx compliance at optimised cost.

All models are certified to robust mechanical standards, including resistance to vibration, corrosion, and impact. The luminaire’s IP66-rated, gasketed enclosures can be specified in rugged 304 stainless steel, 316L stainless steel, or painted 304 stainless steel, each selected for specific corrosion resistance profiles in chemical, marine, offshore, and washdown-intensive environments. The high-impact-resistance housing is rated to 20 Joules (IK10), with a wire guard fitted on tempered glass cover to protect against mechanical impact in high-traffic industrial zones.

In addition, advanced thermal management maintains safe junction temperatures across the full operating temperature range, preserving both lumen output and driver longevity. Lumen maintenance life is estimated at more than 150,000 hours at +55°C (+131°F).

The RNLED and RELED Series are engineered for simple deployment without compromising electrical compatibility or serviceability.

The field-replaceable LED driver allows maintenance technicians to swap the driver module on-site, reducing repair time in hazardous area environments.
