The A14LED Roadway series is a stylized cage acorn post-top luminaire that blends decorative design with modern LED performance. Its construction features a decorative cast aluminum fitter, cage, and hinged roof paired with a molded, high-efficiency prismatic acrylic acorn lens. A cast aluminum ball finial adds a classic finishing detail, giving the fixture a traditional look while supporting advanced lighting technology. The prismatic lens incorporates precisely engineered prisms that distribute light downward for effective illumination while mitigating glare, making the fixture ideal for roadway and pedestrian-scale lighting.
Durability and ease of service are central to the design. The luminaire provides tool-less access to the driver compartment, allowing quick installation and maintenance, while the lens can be serviced in the field without difficulty. The heavy-wall, low-copper aluminum 356 alloy sand-cast fitter delivers excellent corrosion resistance and tensile strength. It features an 8-1/2" inside diameter opening to attach securely to the lens neck, supported by stainless steel Allen-head set screws and a one-piece bug gasket to resist insect penetration. Stainless steel hardware is included throughout, with black oxide coatings used on most finishes and uncoated hardware supplied for light-colored finishes such as whites and silvers.
The luminaire is UL listed under UL1598 and CSA C22.2 No. 250.0 for use in the United States and Canada, and it is suitable for wet locations. At the core of its performance is a UL-recognized electronic driver, installed integrally within the fixture for optimized thermal management and reliability. This high-efficiency driver operates at 50/60Hz, provides constant current output, and includes overload, overheat, and short-circuit protection. It is also designed with quick-disconnect electrical connectors to simplify installation and servicing. With a power factor greater than 0.9 and total harmonic distortion below 20%, the driver supports 0–10V dimming and comes equipped with supplemental surge protection in compliance with IEEE/ANSI C62.41.2 standards. For projects requiring field adjustment, an optional Fixed Dimming Resistor Board (FDRB) allows precise tuning of light output in 10 repeatable steps from 25% to 100%.
The A14LED Roadway series is equipped with vertically mounted, high-brightness Chip on Board (COB) LED assemblies designed to fully illuminate the acorn lens while allowing some uplight for vertical emphasis. These high-output LEDs are RoHS compliant, 100% recyclable, and free of hazardous materials such as lead or mercury. They are tested in accordance with LM-80 and TM-21 standards, with in-situ performance validated by NVLAP-accredited labs. The system offers a predicted lifetime of approximately 100,000 hours at 25°C with more than 70% lumen maintenance. Color temperature options include 2700K, 3000K, 3500K, 4000K, and 5000K, all with a minimum 70 CRI, ensuring flexibility for different applications.
Optical performance is defined by the external prismatic acorn lens, which delivers refractor-type optics with IESNA Type 3, 4, or 5 distributions. Testing is performed in accordance with IESNA LM-79, ensuring accurate photometric performance. Optional internal house-side shielding provides 120° backlight control for projects requiring additional light management.
The finish of the luminaire is achieved through a six-stage polyester powder coat paint system that provides a durable, high-quality surface capable of withstanding extreme environments. This system exceeds AAMA 2604, AAMA 2605, ASTM D523, and ASTM D4214 requirements, with every part inspected for consistency before shipment. Finish options include Sternberg’s Traditional palette, offering textured or smooth colors such as Black, White, Park Green, Architectural Medium Bronze, and Dark Bronze. For applications seeking antique character, the Sternberg Select palette includes finishes such as Old World Gray Textured, Verde Green, and Swedish Iron, incorporating hand-applied antique topcoats that evolve uniquely over time. Custom finishes are also available, including Rust, Weathered Brown, Cedar, Old Iron, and Weathered Black, along with two-tone and color-matching options to blend seamlessly with architectural environments.
Mounting flexibility is another hallmark of the A14LED Roadway series. Configurations include wall mount, post-top, single- and multi-arm mounts at various orientations, mid-mounts, and pier base options, making the luminaire adaptable to a wide variety of streetscape and site designs. Optional lighting controls further enhance versatility, with choices including twist-lock photocontrols for 120–277V or 347–480V systems, electronic button photocontrols, and shorting caps. Photocontrols are pre-wired to the driver and provide reliable, instant-on operation, activating at 1.5 footcandles and deactivating between 2–3 footcandles.
With its combination of decorative styling, robust construction, advanced LED technology, versatile mounting options, and high-quality finishes, the A14LED Roadway series offers a durable, efficient, and aesthetically pleasing solution for roadway, pedestrian, and architectural lighting applications. Its blend of tradition and innovation makes it well-suited for projects where visual character and lighting performance are equally important.
