The Crouse-Hinds series HPLN LED fixtures by Eaton are high-performance hazardous area luminaires designed to deliver reliable, maintenance-free lighting in some of the most demanding industrial environments. Specifically engineered for Zone 1 and Zone 2 hazardous locations, the HPLN LED fixtures are ideal for mid bay and high bay applications, offering a wide lumen output range from 3,000 to 25,000 lumens. This versatility allows them to accommodate mounting heights from 8 feet (2.5 meters) to 40 feet (12 meters), making them suitable for a wide variety of applications including oil and gas refineries, petrochemical plants, offshore platforms, tunnels, pharmaceutical facilities, and other sites where explosive gases, vapors, or dusts may be present.
Constructed for durability, HPLN fixtures feature a copper-free aluminum housing treated with a C5M coating for exceptional corrosion resistance, a tempered and impact-resistant glass globe, and stainless steel guards. The rugged design incorporates an innovative heat sink that optimizes airflow to extend fixture lifespan even in extreme temperatures ranging from -40°C to +55°C. The fixtures are also vibration-resistant and rated to IP66, ensuring protection against water and dust ingress, which is essential for marine, hose-down, and other wet or harsh industrial environments.
Optical performance is a key strength of the HPLN series. Offering efficiency levels of up to 136 lumens per watt, the fixtures are available in cool white (5700K) and warm white (3000K) color temperatures, with additional options of 2700K, 4000K, and 5000K upon request. Custom optics provide narrow (25˚), medium (60˚), and wide (120˚) beam distributions, enabling precise control over light placement to meet varied application needs. A frosted lens option is also available to reduce glare in sensitive areas.
The HPLN LED luminaires are built with flexibility in mind. They support a range of mounting styles including stanchion, pendant, ceiling, wall, and trunnion, allowing adaptation to both IEC and NEC installation standards. This flexibility simplifies retrofit projects and new installations alike. Universal AC/DC input and integrated surge protection (4kV standard, with optional 10kV for offshore applications) ensure stable operation in volatile power conditions.
Certified for use in explosive atmospheres, the HPLN series meets both IECEx and ATEX standards with markings such as Ex db eb mb op is IIC T4 Gb and Ex tb op is IIIC T95˚C Db. Its reliability is backed by certification numbers IECEx PRE 19.0058X and Presafe 19 ATEX 09286X. The fixtures are suitable for continuous use in hazardous environments where reliability and energy efficiency are paramount.
Compared to traditional HID lighting, HPLN LEDs offer significant advantages. They provide instant-on illumination with no restrike delay, consume up to 50% less energy than HID and 85% less than incandescent lights, and deliver superior color rendering. With a rated life of 60,000 hours, they reduce maintenance costs, improve safety by minimizing service intervals, and eliminate hazardous material concerns such as mercury disposal.
In summary, Eaton’s Crouse-Hinds HPLN LED luminaires offer a robust, efficient, and flexible lighting solution for hazardous and industrial locations. Their superior optical design, rugged construction, wide certification coverage, and energy-saving performance make them an excellent choice for demanding environments where both safety and operational efficiency are critical.
