The Nemalux JR is a compact, industrial-grade LED luminaire built for the most demanding environments. Designed to perform in general, marine, and hazardous locations, the JR meets stringent global certifications including UL 844 and CSA C22.2 No. 137, ensuring its reliability in extreme conditions. Its rugged construction, energy-efficient design, and advanced optics make it an exceptional lighting solution for a wide range of industrial applications, from platforms and walkways to modular buildings and marine vessels.
At the heart of the JR is a marine-grade, copper-free aluminum housing coated with a multi-layer powder finish to resist corrosion, UV exposure, and chemical degradation. This robust enclosure also acts as a heat sink, efficiently channeling thermal energy away from the electronics. The fixture’s thermal management is further optimized through a unique design that separates the LED light engine and power supply, maintaining high performance in ambient temperatures ranging from -40°C to +60°C. Optimized fin spacing promotes natural airflow and debris shedding, enhancing component lifespan and system reliability.
Offering lumen outputs between 2,000 and 5,000, the JR is tailored for mounting heights between 8 to 12 feet. Secondary optics provide controlled beam profiles that maximize on-target light delivery while reducing fixture quantity requirements by up to 50% compared to competitors. Whether clear or frosted, the impact-resistant polycarbonate or glass lens provides added durability and protects the internal optics. The perimeter band surrounding the light-emitting surfaces provides a full cutoff for zero up-light, improving operator comfort and visual acuity in industrial settings.
The JR is available with either 120–277 VAC or 347 VAC input options and supports 0–10V dimming. Built-in surge suppression up to 6kV, low total harmonic distortion (THD < 12%), and a field-replaceable driver design make the JR both electrically stable and easy to maintain. The fixture includes three ¾” NPT entries for simplified wiring, supporting daisy-chaining of multiple luminaires on a single circuit. A built-in junction box helps minimize the need for external hardware and simplifies installation, particularly in tight or low-clearance spaces.
The JR series is offered in multiple optical configurations and mounting options, with up to nine different brackets to allow installation in diverse environments. From surface-mounted setups on modular buildings to equipment-mounted lighting for conveyor belts or service vehicles, the JR delivers dependable, targeted illumination. UL1598A marine certification makes it suitable for saltwater-rich environments, while a specialized encapsulated IP68 version (JR-EN) provides watertight protection for submerged applications up to 25 feet. This version is rated for general location use and is engineered to perform at full output whether dry or underwater.
Internally, the JR uses a modular optical platform built on a metal-core printed circuit board (MCPCB), populated with high-efficiency CREE and Samsung LEDs. These LEDs offer superior color rendering (CRI), multiple correlated color temperature (CCT) options, and long-term reliability. The light engine is paired with modular optics that shape the beam to specific application requirements, helping reduce energy usage and increase fixture performance.
In addition to its durability and performance, the JR is designed with field serviceability in mind. All major components—including the LED engine, power supply, and optics—can be replaced in the field by qualified personnel, allowing for cost-effective maintenance over time. This does not apply to the encapsulated JR-EN model, which is sealed permanently for IP68 submersion protection.
To support retrofit projects, Nemalux offers an adapter that allows JR fixtures to be installed using existing Eaton Crouse-Hinds mounting hoods. This reduces labor time and simplifies installation when upgrading legacy systems with modern, energy-efficient LED technology.
With a compact footprint measuring 8.0” x 7.0” x 4.4” and weighing just 2.58 kg (5.68 lbs), the Nemalux JR is engineered to deliver exceptional lighting performance in the most challenging industrial and marine environments—proving that even hazardous location-rated fixtures can deliver advanced optical control, energy savings, and long-term reliability.
