With a CRI of 80+, it ensures accurate color representation for detailed inspections and safety checks. The advanced LED array maintains exceptional lumen depreciation standards with a 100,000-hour L70 lifespan and high luminous efficacy across all variants:
- 66811 — 40W / 120-277V: 6,795 lumens | 171 lm/W
- 66813 — 40W / 277-480V: 6,960 lumens | 172 lm/W
- 66812 — 60W / 120-277V: 9,800 lumens | 167 lm/W
- 66814 — 60W / 277-480V: 10,200 lumens | 170 lm/W
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.
