The Linear Harsh Series from Red Sky Lighting is engineered to endure some of the toughest industrial environments, delivering powerful performance with uncompromising durability. Constructed from rugged, copper-free aluminum and enclosed in a housing rated NEMA 4X, this fixture resists corrosion, high heat, moisture, dust, and vibration, making it ideally suited for harsh conditions found in processing plants, utility spaces, and coastal facilities. With a robust ingress protection rating of IP66, impact resistance of IK08, and UL certifications for wet locations and marine environments, the Linear Harsh Series is built to thrive in both indoor and outdoor industrial settings.
This lighting solution is designed for longevity and energy efficiency. It delivers an impressive rated lifespan of over 147,000 hours even at elevated ambient temperatures up to 149°F (65°C), while also performing reliably in freezing conditions down to -40°F (-40°C). With a high luminous efficacy of up to 150 lumens per watt and available lumen outputs ranging from 4,142 to 11,536 lumens, the fixture ensures consistent, bright illumination while keeping energy costs low. Users can select between color temperatures of 3000K, 4000K, or 5000K with a CRI of 80 for accurate color rendering in work-critical environments.
The fixture supports input voltages ranging from 100-277V AC and 347-480V AC at 50/60Hz, with a power factor ≥0.90 and total harmonic distortion below 20%. It comes with 0-10V dimming capability (10–100%) to accommodate adjustable lighting schemes. Surge protection is built-in, with up to 10kV for 100–277V and tiered protections for higher voltage ranges. It uses supply wires rated to 90°C and accepts 12–18 AWG conductors.
Installation is made simple and flexible with a built-in wiring compartment that includes three ¾" NPT conduit entries and WAGO 221 lever connectors for secure, tool-free wiring. The fixture supports multiple mounting configurations such as pendant, yoke, chain, pole, and stanchion. A retrofit bracket is also available for easy replacement of legacy luminaires, and the fixture is compatible with both 2" (2 3/8" OD) and 1.5" (1.9" OD) poles—threaded or non-threaded.
Additional components such as the multi-piece junction box offer further flexibility. It features a copper-free cast aluminum housing, a durable front cover, and a cable gland that supports both standard and stanchion mounting options. The robust design and stainless steel 316 hardware further enhance corrosion resistance and reliability in marine and industrial applications.
The Linear Harsh Series is backed by a 10-year warranty on LEDs and a 7-year warranty on the driver, ensuring long-term value and performance. It is fully certified by UL1598, UL1598A (Marine Outside Type, Salt Water), CSA C22.2 NO. 250.0, and complies with FCC Part 15, Subpart B, and DLC Standard criteria—making it a proven, energy-efficient choice for demanding environments.
