Effective Illumination for Industrial Applications

Light Fixture Performance

3,000 – 6,000 lumen output multi-functional LED light fixture for typical mounting heights of eight (8) to fourteen (14) feet.

Optimized Lighting Effect

Secondary optics provide advanced optical profiles to reduce the number of lights required. Quantity reductions of up to 50% are possible compared to some competing designs.

Superior Results

Targeted illumination levels and visual comfort are both achievable. Proving that hazardous location-rated lights can deliver excellent optical performance.

Improved Visibility

Impact-resistant polycarbonate lenses protect the LEDs and secondary optics and reduce glare. Visual acuity improves operator comfort and effectiveness.

Engineered for Extreme Environments

Protected Against the Elements

Copper-free aluminum alloy housing acts as the heat sink, featuring IP66/IP67 protection.

Extended Luminaire Life

Optimized fin spacing promotes debris shedding and convective airflow. It lowers operating temperatures and extends the life of internal components.

Designed for Harsh Environments

Multi-layer powder coat provides chemical and UV resistance in corrosive locations. Here is a complete list of the MR's Performance Specs.

Dark Sky

Perimeter bands surround all light-emitting surfaces to provide a full cut-off. Projects requiring Dark Sky (IDA) rating can deploy specific MR models.

Simplified Installation & Operation

Installation Options

A variety of mounting brackets permit installation of the MR in challenging locations.

Implementation Areas

Applications for the MR include lighting walkways, platforms, conveyor belts, and building perimeters. Surface-mounted models fit modular buildings and other low-clearance spaces. Solid state components enable deployment on service equipment. Standard UL1598A marine ratings make the MR suitable for saltwater locations.

Light Fixture Connection & Maintenance

A built-in junction area with three 3/4” NPT entries allows for through wiring, which reduces the need for external junction boxes. Component replacements with the MR do not need soldering, allowing field repair lifetime extensions with driver and LED module replacements and upgrades.


MR Series -  Beam Profile Selection Guide  ​nemalux-mr-series-optics-beam-profile-c

Solid-state technology provides an excellent opportunity to deliver light on target surfaces effectively. Combining LEDs with secondary optics shapes the light output to increase the amount of usable light. Inside the MR fixture, the location of the optics is behind a protective lens. Optics offer flexibility during lighting design and application, reducing installation and operation costs.

MR Series -  IP68 Encapsulated Variant (MR-EN) ​Hazardous Location Encapsulated LED Light | 3,000 – 6,000 Lumen IP68 Luminaire | Class I Division 2 Subversive Light | MR Series from Nemalux

LED lights can face submersion for an extended period in certain applications. This challenge is also present in some industrial, infrastructure and maritime locations.​

Nemalux offers a version of the MR that is suitable for IP68 applications. An optically clear encapsulant creates a permanent seal. Maintaining protection against the ingress of water to a depth of up to 25'. The MR-EN model operates at full output in dry as well as submerged conditions.
