The ProSite Heavy-Duty Series is the latest evolution of Dialight’s renowned ProSite Floodlight family, engineered specifically to meet the demanding needs of mobile plant and heavy equipment operating in extreme industrial environments. Developed for high-vibration applications such as container cranes, stackers, reclaimers, and dragline excavators commonly found in ports and mining operations, this series introduces a robust new reinforced bracket design that ensures stability, safety, and lasting performance under constant mechanical stress. By minimizing light flicker and delivering consistent, high-quality illumination, the ProSite Heavy-Duty Series supports safety and visibility in the harshest conditions.
Capable of producing up to 65,000 lumens and delivering efficacy up to 165 lumens per watt, the fixture provides powerful lighting suitable for mounting heights up to 100 feet (30 meters). It supports multiple beam distribution options including NEMA 4, NEMA 6, NEMA 7x6, Asymmetric, and Asymmetric Wide, offering flexible lighting coverage for diverse operational needs. With a broad color temperature selection—ranging from warm amber and 2200K or 2700K warm white to 4000K neutral white and 5000K cool white—the ProSite Heavy-Duty Series ensures visually optimized environments with a standard CRI of 70, and an optional upgrade to 80 CRI for more accurate color rendering.
The fixture’s construction is as rugged as its lighting performance. The housing is made from A360 die-cast aluminum and paired with 316 stainless steel hardware and mounting brackets—available in straight, angled, and heavy-duty configurations—for superior corrosion resistance and mechanical strength. It features a superior epoxy and polyester dual-coat finish for long-term durability in outdoor and corrosive environments. Lens options include an integrated polycarbonate optic, a glass lens cover, and a polycarbonate lens cover, with IK10 impact protection on the PC lens and IK08 on the glass variant.
Designed for both hazardous and non-hazardous area use, the ProSite Heavy-Duty Series is certified to UL 1598/A, UL 844 for Class I Division 2, Class II Divisions 1 and 2, and Class III locations, as well as CSA, CE, ENEC, RCM, and IECEx/ATEX for Zone 2, 21, and 22. Its performance is unaffected by harsh environmental extremes, operating in temperatures from -40°F to +149°F (-40°C to +65°C), making it suitable for virtually any climate or industrial setting.
Electrically, the floodlight supports input voltages ranging from 120-277 VAC, 120-250 VDC, and an extended high-voltage range of 347-480 VAC. It boasts a power factor greater than 0.9, total harmonic distortion (THD) of less than 20%, and electromagnetic compatibility with FCC Title 47 CFR Part 15 Subpart B Class A. It meets IEC standards for flicker (IEC 61000-3-3), immunity (IEC 61547), harmonics (IEC 61000-3-2 Class C), and transient protection (IEC 61000-4-5), with built-in surge protection for 6kV line-to-line and line-to-ground conditions. Optional external surge protection modules rated for 10kA or 20kA single strikes are also available for enhanced protection.
The ProSite Heavy-Duty Series offers advanced control capabilities with standard compatibility for DALI 2.0 and 0-10VDC dimming, along with optional wireless dimming integration through Dialight’s IntelliLED intelligent controls. With a shipping weight of up to 48 lbs (21.6 kg) and an effective projected area (EPA) of 2.00 square feet, the luminaire is engineered for structural efficiency without compromising on strength or performance.
Backed by a 10-year warranty, the ProSite Heavy-Duty Series is a premium solution that brings together high-output lighting, robust construction, and intelligent design to meet the intense demands of industrial lighting in hazardous and mobile environments.
