The Round Max Harsh Series by Red Sky Lighting is an industrial-grade LED lighting solution engineered for uncompromising performance in the most demanding environments. Delivering up to 30,000 lumens with beam angle options including Type I, III, V, 30°, and 60°, this fixture excels in mid- to high-bay applications across industries such as shipbuilding, power generation, water and wastewater treatment, metal processing, pulp and paper, agriculture, and heavy manufacturing. Its versatile beam patterns enhance illumination efficiency by reducing the total number of fixtures needed to achieve optimal light distribution across wide or focused areas.
Built to withstand extreme operating conditions, the Round Max Harsh Series features a rugged, copper-free aluminum housing and corrosion-resistant 316 stainless steel hardware. The fixture is available with either a tempered glass or polycarbonate lens and offers a wide selection of mounting options including pendant, ceiling, stanchion, wall, yoke, junction box, and slip fitter configurations. With an ambient temperature tolerance ranging from -40°F to +149°F, and wind ratings up to 1.372 ft² EPA depending on the mounting configuration, the fixture is designed for reliable performance in both indoor and outdoor installations.
Its advanced 0-10V dimming system allows for flexible control from 10% to 100%, with a power factor of ≥0.90 and total harmonic distortion kept under 20%. Voltage compatibility spans 100-277V AC, 347-480V AC, and 120V or 208-277V AC at 50/60Hz. Lumen packages include 12,157, 17,388, 21,771, and 26,076 lumens, all achieving a high efficacy of 148 lumens per watt. Color temperature options of 3000K, 4000K, and 5000K ensure compatibility with a wide range of visual tasks and aesthetic requirements, all rated at a high color rendering index (CRI) of 80 for improved visibility.
Durability is a core focus of the Round Max Harsh Series. The fixture is NEMA 4X and IP66 rated for water and dust resistance, and tested to withstand 720 hours of salt spray in accordance with ISO 9227. It also carries multiple industry certifications including UL 1598 for wet locations, UL 1598A for marine outside-type (salt water) environments, CSA C22.2 No.250.0, and is listed to meet DLC Standard* and FCC Part 15, Subpart B requirements. Impact protection is rated at IK08 for glass lenses and IK10 for polycarbonate lenses. With an L70 lifespan of up to 112,000 hours at high temperatures, this fixture significantly reduces maintenance costs and supports long-term reliability in mission-critical operations.
A standout feature of the Round Max Harsh Series is its ultra-fast installation process—taking as little as 60 seconds—making it an ideal drop-in solution for retrofitting or new construction in facilities requiring robust, energy-efficient, and instantly deployable lighting. This series is purpose-built for the most unforgiving industrial applications and delivers dependable, high-output LED illumination with uncompromising safety, longevity, and ease of use.
