Electrical & Controls
Each fixture in this series is equipped with a highly efficient universal driver — 120-277V for standard commercial and industrial power grids, or 277-480V for high-voltage industrial installations. All configurations feature standard 0-10V dimming capabilities, allowing for integration with automated facility lighting systems. The internal electrical components are engineered to handle industrial power fluctuations safely.
Construction & Durability
The housing is constructed from rugged SUS304 stainless steel to resist corrosion in caustic chemical environments. A UV-stabilized, impact-resistant polycarbonate lens protects the internal components from the high-vibration stress common in heavy industrial applications. The complete luminaire is IP66 and IK08 rated, sealing it against heavy dust and direct high-pressure water streams while operating reliably between -40°F and 122°F. Dimensions: 51.26" L × 8.66" W × 7.28" H.
Compliance & Certifications
All models in this series are certified for Class I, Division 2 and Class II, Division 1/2 hazardous locations, making them suitable for environments with flammable gases, vapors, combustible dust, and ignitable fibers. The IP66 rating ensures complete protection against dust ingress and powerful water jets.
Installation & Mounting
These fixtures support versatile installation in hazardous zones via suspended or continuous superimposed assemblies using standard conduit pipe, ensuring a rigid installation that mitigates vibration and prevents shifting over time in demanding operational environments.
