The Dialight ProSite Streetlight is a next-generation outdoor lighting solution designed to deliver exceptional performance, energy efficiency, and durability in the harshest industrial environments. Engineered for critical infrastructure applications, this fixture offers superior illumination with advanced chip-scale package (CSP) LEDs and proprietary molded optics that maximize light output while maintaining a compact, streamlined profile. With lumen packages ranging from 12,000 to 30,000 lumens and an impressive efficacy of up to 155 lumens per watt, the ProSite Streetlight delivers brilliant, near-daylight visibility ideal for roadways, perimeters, and parking areas in demanding sectors such as Oil & Gas, Petrochemical, Chemical, Mining, Metals, and other heavy industrial operations.
Built to withstand the toughest conditions, the ProSite Streetlight carries a wide range of global certifications, including UL 1598/A, UL 844 (for Class I, Division 2; Class II, Divisions 1 and 2; and Class III), CSA, CE, ENEC, RCM, and IECEx/ATEX for use in Zone 2, 21, and 22 hazardous areas. The fixture is rated to IK10 impact protection when configured with the integrated polycarbonate lens and IK08 with the optional glass lens cover. It is further protected by a dual-layer epoxy and polyester powder coat finish applied to a rugged A360 die-cast aluminum housing, ensuring resistance to corrosion, UV degradation, and abrasion. All hardware is constructed from 316 stainless steel for maximum resistance to corrosive elements.
Designed to operate in extreme temperatures, the ProSite Streetlight performs reliably in ambient conditions ranging from -40°F to +149°F (-40°C to +65°C). It supports a wide input voltage range of 120-277 VAC, 120-250 VDC, and 347-480 VAC, with optional surge protection modules offering up to 20kA single-strike protection. Standard transient protection is rated at 6kV/3kA. The fixture supports both 0-10V dimming and compatibility with DALI 1.0 and 2.0 protocols, enabling integration into intelligent lighting control systems. A NEMA 3-pin receptacle with shorting cap is included for optional photocell operation, enhancing energy efficiency and automation in outdoor settings.
Optical versatility is a key feature of the ProSite Streetlight, offering multiple IES beam distributions—Type II Medium, Type III Short, Type III Medium, and Type V—to meet diverse application requirements. Available color temperatures include 5000K (cool white), 4000K (neutral white), 2700K and 2200K (warm white), and Amber, with a standard 70 CRI and optional 80 CRI for improved color rendering. These photometric options allow for tailored lighting designs that prioritize visibility, safety, and visual comfort across a wide range of industrial installations.
The ProSite Streetlight is offered with flexible mounting configurations, including a cast aluminum mast arm bracket designed for 1.66” to 2.37” OD pipes with tilt settings of -5°, 0°, and +5°, and a slipfitter bracket for vertical pole mounts with a 7.5° tilt adjustment. The fixture has a wind-exposed surface area (EPA) of 1.11 square feet and a ¾” NPS cable entry for streamlined installation.
Electrically, the fixture is optimized with a power factor greater than 0.9 and total harmonic distortion (THD) under 20%. It complies with multiple global standards for electromagnetic compatibility and electrical performance, including FCC Title 47 Part 15 Subpart B Class A for emissions, IEC 61000-3-3 for flicker, IEC 61547 for immunity, and IEC 61000-3-2 Class C for harmonics.
Backed by a 10-year warranty, the Dialight ProSite Streetlight sets a new standard in industrial outdoor lighting—delivering reliable, high-output, and intelligent illumination that enhances safety, efficiency, and operational continuity across the most demanding work sites.
