The Round-Max luminaire is a powerful and reliable lighting solution designed to meet the rigorous demands of indoor mid to high bay applications and outdoor general area illumination. Engineered for performance and versatility, this fixture is particularly well-suited for high-impact industrial environments such as oil and gas refineries, shipyards, metal processing plants, agriculture operations, pulp and paper mills, wastewater treatment facilities, and power generation sites. Its high lumen output—available in configurations producing up to 30,000 lumens—combined with precision optics in Type I, III, and V distributions ensures efficient and uniform lighting, reducing the total number of fixtures required across large spaces.
The Round-Max is built to withstand the most challenging environmental and hazardous conditions. It meets stringent safety and performance standards, including Class I Division 2 Groups A, B, C, and D; Class II Division 1 Groups E, F, and G; Class II Division 2 Groups F and G; and Class III classifications. It carries certifications under UL 844 for hazardous locations, UL 1598 for wet locations, UL 1598A for marine vessel applications with salt spray exposure, and UL 8750 for LED safety. Additional certifications include CSA C22.2 standards and IP66 ingress protection, ensuring resistance to dust and water ingress. It is also DLC qualified for energy efficiency.
Technically advanced, the Round-Max operates on a wide input voltage range of 100-277V AC or 347-480V AC at 50/60Hz, with a high power factor (≥0.90) and total harmonic distortion under 20%. The fixture supports 0-10V dimming, allowing a dimming range from 10% to 100%, and features 6kV surge protection for added reliability. It offers exceptional longevity with L70 rated lifespans exceeding 110,000 hours even in elevated temperatures up to 149°F (65°C), ensuring minimal maintenance and maximum operational uptime.
The Round-Max delivers an impressive efficacy of up to 150 lumens per watt and is available in multiple lumen packages: 12,720 lm, 19,320 lm, 23,850 lm, and 29,600 lm. Color temperatures include 3000K, 4000K, and 5000K, with a CRI above 70 for good color rendering in industrial settings. Beam angle options such as T1 and T5 are available to tailor light distribution to specific site requirements.
Constructed with durability in mind, the fixture features a corrosion-resistant housing made of copper-free aluminum (less than 0.4% copper content), stainless steel 316 hardware, and a choice of tempered glass or polycarbonate lenses. Installation is flexible with mounting options that include pendant, ceiling, stanchion, wall, and yoke mounts. The Round-Max weighs 21.6 lbs (9.8 kg) and includes six ¾-inch NPT cable entries to accommodate various wiring configurations. Its EPA wind ratings range from 1.222 to 1.372 square feet depending on the mounting method.
The Round-Max combines cutting-edge LED efficiency with rugged industrial durability, offering a next-generation lighting solution that delivers superior performance, safety, and reliability in demanding environments.
