The 1921LED Galesburg luminaire is a large-scale, bell-shaped downlight pendant designed to provide both decorative and functional illumination for roadway and area applications. Its distinctive design combines classic architectural appeal with modern LED technology, making it ideal for urban streetscapes, campus pathways, municipal areas, and other outdoor public spaces. The fixture’s substantial presence is complemented by precision-cast aluminum construction, which ensures both durability and a refined aesthetic suitable for contemporary or traditional project environments.
The luminaire’s housing is fabricated from heavy wall aluminum castings, providing high tensile strength and long-term resistance to outdoor elements. Its thermal design is optimized for LED performance, with LEDs mounted to maximize heat transfer to the heat sink. These high-brightness, high-output white LEDs are fully shielded in a downward-facing orientation to maximize efficiency, minimize glare, and provide uniform illumination across the fixture’s surface. The LEDs are RoHS compliant, 100% recyclable, and free from hazardous materials, including lead and mercury. Lumen maintenance is based on IESNA TM-21 standards and LM-80 testing, projecting up to 100,000 hours of operation at 70% of initial output, with color temperatures available in 2700K, 3000K, 3500K, 4000K, or 4500K and a minimum CRI of 70, ensuring high-quality visual performance for a wide range of outdoor lighting needs.
Installation flexibility is a core feature of the Galesburg luminaire, with multiple mounting options including wall mounts, single or multiple arm mounts, mid-mount configurations, chain-hung, and stem-hung setups. For hanging applications, the fixture requires a hang-straight transition, available in standard horizontal (HSHx) versions with spike, ball, or no finial, as well as the vertical EZ hang-straight for simplified installation. The hang-straight design accommodates horizontal and vertical tenons for seamless integration into various site configurations. Arm-mount and other mounting solutions provide a streamlined aesthetic while maintaining structural stability and ease of installation.
Serviceability has been carefully considered in the luminaire’s design. Tool-less access to the driver compartment simplifies installation and maintenance, while the lens can be serviced in the field with minimal effort. The driver is UL recognized, installed integral to the luminaire, and designed for longevity and efficiency. It operates at 50/60Hz, supports 0–10V dimming protocols, and includes overload, overheat, and short-circuit protection. Supplemental surge protection is provided in accordance with IEEE/ANSI C62.41.2 guidelines, ensuring reliable operation in outdoor electrical environments. A quick-disconnect connector on the power supply allows for fast and convenient wiring during installation or maintenance.
The luminaire offers multiple lens options to enhance optical performance and visual comfort, including flat glass, sag glass, frosted sag glass, ribbed acrylic teardrop, and SoftVue™ diffused acrylic in light and moderate diffusion levels. Optional glare-reducing SoftVue™ lenses contribute to visual comfort in areas requiring reduced light intensity or softer illumination. Backlight and glare control is further supported through optional house side shields (HSS) and internal backlight optical control (BLOC) configurations, which can be adapted depending on lens selection to optimize dark-sky compliance. The Galesburg luminaire achieves NightSky® friendly status with dark-sky design properties and a U0 BUG rating for specific configurations, minimizing light pollution while maintaining effective roadway and area illumination.
Customization options extend to finish, hardware, and accessory configurations. The 1921LED Galesburg features a 6-stage polyester powder coat paint system, exceeding AAMA 2604, AAMA 2605, ASTM D523, and ASTM D4214 standards. Traditional finishes include Black, White, Park Green, Architectural Medium Bronze, and Dark Bronze, while the Sternberg Select palette offers antique-inspired finishes such as Old World Gray, Verde Green, and Swedish Iron. Specialty finishes including Rust, Weathered Brown, Cedar, Old Iron, and Weathered Black provide additional versatility, with two-tone and custom match options available to integrate seamlessly with site-specific aesthetics. Stainless steel hardware is included, with black oxide coating for darker finishes and uncoated hardware for lighter finishes.
Control options include photocells, twist-lock and button types, supporting instant-on operation with configurable on/off thresholds for 1.5 to 3 footcandles, suitable for both hang-straight and pole-mounted installations. Optional fixed dimming resistor boards (FDRB) allow field-adjustable light levels from 25% to 100%, providing precise control over lighting intensity. Additional accessories include double fuse holders for enhanced protection and optional house side shields for backlight control. These options ensure that the luminaire can meet a wide range of site-specific performance, aesthetic, and regulatory requirements.
In summary, the 1921LED Galesburg luminaire is a versatile and durable outdoor lighting solution, offering large-scale decorative appeal, superior LED performance, customizable optics and finishes, and multiple mounting and control options. Its combination of classic design, dark-sky compliance, and high-quality construction makes it ideal for roadway, area, and architectural lighting applications where style, performance, and adaptability are equally important.
