The Round Harsh Series from Red Sky Lighting is a compact, high-performance industrial lighting solution designed for the most demanding environments. Encased in a rugged 9-inch die-cast aluminum housing, this fixture is engineered to deliver up to 150 lumens per watt, with a total output ranging from 4,802 to over 9,100 lumens depending on the configuration. Its high efficacy ensures optimal illumination while minimizing energy consumption—ideal for tight or confined industrial spaces where performance cannot be compromised. Built to endure extreme environments, it operates reliably in temperatures ranging from -40°F to 140°F (-40°C to 60°C), while offering over 127,000 hours of rated lifespan (L70) at peak thermal loads.
The fixture’s sealed, corrosion-resistant design meets NEMA 4X and IP66 ratings, providing robust protection against water, dust, salt spray, and impacts (IK08 rated). It is UL 1598 and UL 1598A certified for wet locations and marine (saltwater) outdoor use, further reinforced by ISO 9227 salt spray resistance testing to 720 hours. The Round Harsh Series is also DLC Premium listed and FCC compliant, with CSA C22.2 No. 250.0 certification for North American applications. Integrated surge protection up to 10kV, combined with a power factor ≥0.90 and low total harmonic distortion (<20%), ensures stable, long-lasting operation even in power-sensitive facilities.
Offering a versatile lighting platform, the Round Harsh Series comes with multiple beam angles (60° and 120°), color temperatures (3000K, 4000K, 5000K), and mounting configurations. Whether it’s pendant, yoke, pole, stanchion, ceiling, or wall mounting, the system’s universal interface fits standard ¾" NPT hubs for broad compatibility. An integrated 0-10V dimming driver enables smooth control from 10% to 100%, supporting light pollution reduction and energy efficiency strategies.
Ideal for sectors such as metal processing, agriculture, power generation, water and wastewater treatment, and pulp and paper production, this fixture is engineered to withstand vibration, contaminants, and thermal stress. Its pre-installed, customizable supply cords simplify installation across a range of industrial applications. Featuring stainless steel 316 hardware, tempered glass lenses, and high-lumen LED performance, the Round Harsh Series combines compact form with industrial-grade resilience—making it the ultimate solution for harsh area, flood, high bay, and low bay lighting applications.
