Effective Illumination for Industrial Applications

Light Fixture Performance

8,000 – 20,000 lumen output multi-functional LED light fixture for a typical mounting height of 8’ to 25’. Auto-ranging power supplies allow operation on 120-277 VAC or 347-480 VAC. Standard power supplies are 0-10V dimmable. Allowing fine-tuned illumination results based on facility and operator preference.

Optimized Lighting Effect

Secondary optics provide a wide range of optical profiles. Increasing light fixture spacing and lighting quality. Quantity reductions of up to 25% are possible when compared to other LED lights.

Improved Visibility

Impact-resistant polycarbonate lenses provide protection for LEDs. Ultra-efficient secondary optics deliver high lumen per watt ratios. Select models qualify for DLC. Advanced manufacturing processes result in textured lenses for flood models. This improves the visual comfort of facility operators.

Dark Sky

Perimeter bands surround all light-emitting surfaces, providing a full cut-off feature. Certain XR models are suitable for sensitive environments requiring dark sky (IDA) listing.

Engineered for Extreme Environments

Protected Against the Elements

Copper-free and aluminum alloy housing acts as the heat sink, featuring IP66 protection. Pressure equalization membranes allow for humidity control without stressing the electronic.

Designed for Harsh Environments

Multi-layer powder coat provides chemical and UV resistance in corrosive locations. Allowing long-term deployment in certain corrosive outdoor and indoor locations. Here is a complete list of the XR's Performance Specs.

Superior Results

Using Nemalux luminaires we deliver visual comfort and outperform lighting targets.

Extended Luminaire Life

Optimized fin spacing promotes debris shedding and convective airflow. This extends the life of the internal components. Proprietary design features allow thermal separation of the power supply and LED heat sink. Physical separation of housing elements is not required for this effect. The reduction of thermal interaction between the electronics increases the ambient temperature rating.

Simplified Installation & Operation

Installation Options

The XR has 8 standard mounting options providing installation flexibility. Furthermore, custom mounting allows installation in challenging locations.

Implementation Areas

Areas of application include area, platform, and pole top lights. Building perimeter illumination with the help of wall mount and yoke brackets. Simplified future access using wall packs for indoor and outdoor installation. Low and high-bay use with surface, conduit, or hook-mounted lights. Other areas include modular buildings, marine vessels, and mining equipment.

Light Fixture Connection & Maintenance

Built-in junction area with three ¾” NPT entries allows for through wiring. Reducing the need for external junction boxes. Solder-free component replacements are possible with the XR. Allowing end-of-life driver and LED module replacements and upgrades.


XR Series -  Beam Profile Selection Guide  ​nemalux-xr-wc-lens-optics-600b

LED lights are a great platform to improve performance by integrating optics. This integration delivers light to target surfaces to enhance visibility. The optics on the XR also act as the protective lens. Optics maximize flexibility during the lighting design process and reduce costs during installation.
