The Crouse-Hinds series HPL LED fixtures by Eaton are purpose-built for safe and efficient illumination in hazardous locations, specifically those falling under Zone 1 and 2 for explosive gases and Zone 21 and 22 for combustible dust. These low-profile, industrial-grade luminaires are ideal for general area lighting in environments such as chemical and pharmaceutical plants, heavy industrial sites, electric power stations, marine and shipyard facilities, wastewater treatment plants, loading docks, and paper mills. Offering exceptional versatility, the HPL LED is available in four model variants delivering light output from 3,000 to 8,000 lumens, making it a reliable replacement for conventional HID light sources up to 175W. Additionally, an emergency lighting version is available, providing 1.5 to 3 hours of illumination during power interruptions.
Designed for both indoor and outdoor use under the harshest environmental conditions, HPL LED fixtures are engineered to perform in areas with dust, vibration, moisture, corrosive chemicals, and extreme temperatures. They provide a high efficacy of over 100 lumens per watt, resulting in up to 66% energy savings compared to traditional HID lighting. The robust design features a compact and lightweight housing made from copper-free aluminum, combined with a heat- and impact-resistant tempered glass globe. With a high degree of ingress protection (IP66), these fixtures offer exceptional resistance to water and dust ingress, making them suitable for use in rugged industrial applications.
The HPL LED’s optical performance and long service life contribute to significant reductions in maintenance and energy costs. Equipped with high-efficiency LED modules, the system achieves up to 100,000 hours of LED lifetime (L70) and up to 100,000 hours for the driver (C10), both rated at a 25°C ambient temperature. Available color temperatures include cool white (5700K) and warm white (3000K), with other CCT options available upon request. The fixture delivers a color rendering index (CRI) greater than 70, ensuring consistent and high-quality light output. The high-performance heat sink design ensures optimal thermal management, supporting operation in ambient temperatures ranging from -40°C up to +50°C, depending on the application type.
Mounting flexibility is a key advantage of the HPL LED. Multiple mounting options—including pendant, ceiling, wall, yoke, and pole installations—support a wide variety of field applications and site conditions. Emergency versions of the fixture are also equipped with a Ni-Cd 3Ah battery that powers 30% of the light output for 1.5 hours, or 15% for 3 hours (upon request), ensuring operational continuity and safety in critical situations. The enclosure is finished in grey powder-coated light alloy, and the standard model weighs 5 kg, while the emergency version weighs 6.5 kg.
The electrical design supports a wide input range from 100-240V AC and 108-250V DC, with frequency compatibility from 0 to 60 Hz. The power factor is ≥0.9, supported by an electronic driver and a Class I protection rating. The fixture also features two M25 metal thread cable entries, one of which includes a plastic plug; M20 entries are available upon request. The protective clear glass cover is toughened for durability, and an opaque option is available for glare-sensitive applications. A sheet steel swivel bracket is included as standard, with a stainless steel version offered upon request.
Certifications and compliance for the HPL LED are extensive. It holds the EC-Type Examination Certificate EPT 16 ATEX 2405X, IECEx Certificate of Conformity IECEx CQM 15.0054X, and GB Certificate GYJ15.1157X. Compliance markings include Ex II 2 G Ex db eb mb op is IIC T6 Gb and Ex II 2 D Ex tb op is IIIC T80˚C Db per 94/9/EC, with equivalent IECEx and GB system markings. The fixture is designed to meet international standards for hazardous locations, ensuring safe performance in environments where explosive gases, vapors, and dusts are present.
Altogether, the Crouse-Hinds HPL LED series offers a high-reliability lighting solution that combines rugged construction, efficient LED performance, and full hazardous area certification. Whether used for routine operations or as emergency lighting, these fixtures support continuous, maintenance-free operation while enhancing safety, visibility, and energy efficiency in the most demanding industrial settings.
