Engineered with advanced Cree LED technology and a corrosion-resistant aluminum housing, this high-output luminaire delivers superior brightness, longevity, and protection. With a 141.9° wide beam angle and luminous efficiency of 120 lm/W, it’s the ideal choice for facilities requiring reliable, explosion-proof overhead lighting in critical zones.
Certified Safety in Hazardous Zones
Built for the most demanding industrial applications, the VL-EXLG8231-XX carries an explosion-proof grade of Ex d IIC T6, ensuring safe operation in Zone 1 and Zone 2 gas environments and Zone 21 and 22 dust environments. Compliant with GB3836.1 and GB3836.2 standards, the lamp is protected by a die-cast aluminum alloy housing and tempered glass cover. Its IP66-rated enclosure offers complete protection against dust ingress and high-pressure water jets, while the WF2 anti-corrosion grade ensures durability in harsh chemical or marine conditions.
Superior Illumination with Energy Efficiency
This long hanging lamp is powered by a high-performance Cree LED array consisting of 80 diodes, offering a total luminous flux of 120 lumens per watt. The unit operates with a power factor greater than 0.95, minimizing energy losses and reducing operational costs. Its color rendering index (CRI) of ≥75 Ra ensures accurate visibility of workspaces and equipment, while the color temperature range of 3000K–6500K accommodates both warm and daylight-like lighting conditions.
The wide beam angle of 141.9° guarantees broad area coverage, making it ideal for illuminating large industrial floors, corridors, or processing stations from overhead mounts. Despite its high output, the VL-EXLG8231-XX starts instantly in ≤0.2 seconds, ensuring uninterrupted lighting even in emergency scenarios.
Engineered for Longevity and Low Maintenance
With a 100,000-hour LED operating life, the VL-EXLG8231-XX offers long-term, maintenance-free operation in demanding work environments. The fixture supports an input voltage range of AC 100V–270V and operates flawlessly at -30°C to 50°C (-22°F to 122°F), making it suitable for both indoor and outdoor use across a wide range of industrial applications.
Each unit weighs 6.4 kg (14.1 lbs.) and is housed in a durable 230 × 307 mm (9 × 12 in) shell, ensuring both ease of installation and secure mounting. The robust structure makes it an excellent fit for overhead cable trays, gantry systems, or pendant-style mounts in industrial facilities.
Compact Packaging and Bulk Shipping
The VL-EXLG8231-XX is also optimized for shipping and deployment. Each fixture is packed in a 35.1 × 31.6 × 29.2 cm (13.8 × 12.4 × 11.4 in) carton with a gross weight of 7.4 kg, while a master carton contains 4 units, totaling 18 kg. This format ensures efficient bulk shipping and easy on-site inventory management.
