The Crouse-Hinds series Pauluhn ZPLA Explosionproof Linear LED Light Fixtures are engineered for demanding industrial environments, offering a highly durable and efficient alternative to traditional fluorescent T12, T8, and T5HO lighting. Specifically designed for hazardous locations, including marine vessels and land-based or offshore drilling platforms, the ZPLA series is available in 2-foot and 4-foot configurations, delivering luminous outputs of 3,800 lumens and 8,300 lumens respectively. These fixtures are purpose-built for high-vibration, impact-prone areas and are ideal for applications requiring frequent hose-down, such as mud rooms, derricks, SCR houses, masts, and operator stations.
Constructed to withstand harsh and hazardous conditions, the ZPLA is certified for use in Class I, Division 1, Groups C and D; Class II, Division 1, Groups E, F, and G; and Class III environments. It meets NEMA 4X and IP66 standards for marine and wet locations and is paint spray rated. Additional certifications include UL standards (UL50E, UL844, UL924, UL1598, UL1598A, UL8750) and CSA C22.2 Nos. 137 and 250, affirming its compliance with stringent industrial safety and performance requirements.
One of the standout features of the Pauluhn ZPLA is its longevity and reliability. The fixture boasts a rated lifetime of 60,000 hours at ambient temperatures up to 55°C, and over 100,000 hours at 40°C or below, making it a long-term lighting solution for challenging environments. Operating at an efficacy of up to 139 lumens per watt (LPW), the ZPLA delivers high-output lighting with exceptional energy efficiency. It offers a 5000K correlated color temperature (CCT) and a color rendering index (CRI) of 72, ensuring bright and natural illumination that enhances visibility in critical workspaces.
The fixture’s robust mechanical design includes a copper-free aluminum housing with optional Corro-free epoxy powder coating, and a durable glass lens, with a diffused glass option available. With a low profile height of under 5 inches (excluding mounting hardware), the ZPLA is perfect for use in confined or low-clearance areas. Installation is made easy with flush and swivel mount options, accessible drivers and wiring, and no need for custom brackets. Additionally, four points of secondary retention and loop feed wiring enhance safety and ease of wiring during installation.
Designed for durability, the ZPLA is resistant to vibration, shock, and impact, having passed a 5G 3-axis vibration test. The fixture also features ingress protection against high-pressure hose-downs and contaminants like diesel fuel, passing a 2,000 PSI pressure test. Surge protection is built in, rated at 4kV line-to-line and 6kV line-to-earth. A 5-year warranty is standard for the base models, while emergency battery units include a 1-year warranty.
For critical applications requiring uninterrupted lighting during power failures, Pauluhn ZPLA offers emergency lighting solutions that are explosion proof-rated for both indoor and outdoor use. These models operate in ambient temperatures from -20°C to +40°C, offer a minimum 90-minute runtime in emergency mode, and deliver 7,513 lumens in normal operation (784 lumens in emergency mode). They are housed in IP66-rated enclosures with NiCad batteries and include a manual test switch and LED indicator for battery status monitoring. The rated life for emergency units is 60,000 hours at 40°C, ensuring reliable performance during outages.
Altogether, the Pauluhn ZPLA explosionproof linear LED fixtures combine high lumen performance, rugged reliability, and ease of installation, making them an ideal choice for hazardous, high-impact industrial environments where performance and safety cannot be compromised.
