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.

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.

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.

Improved Visibility

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

Designed for Harsh Environments

Multi-layer powder coat provides chemical and UV resistance in corrosive locations.

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.
