Performance & Light Output

This fixture generates 6,000 lumens with a crisp 5000K daylight color temperature, maximizing visual acuity for critical tasks. 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, offering a 100,000-hour L70 lifespan with high luminous efficacy.

Electrical & Controls

Equipped with a highly efficient 120-277V universal driver, this linear luminaire ensures stable operation across standard commercial and industrial power grids. It features 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.

Installation & Mounting

This specific configuration is designed for versatile installation in hazardous zones. It supports 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.
