The A45LED Palmetto Series is a stylized Victorian acorn post-top luminaire that combines traditional elegance with modern LED performance. Its construction features a decorative cast aluminum fitter, a spun roof, and a high-efficiency prismatic acrylic acorn, topped with a decorative urn finial. This design allows the fixture to deliver both historical charm and advanced illumination performance for a variety of architectural, municipal, and streetscape applications.
Built with durability in mind, the fitter is made from heavy-wall, low-copper aluminum alloy for superior corrosion resistance and tensile strength. It includes an 8.5-inch inside diameter opening to attach securely to the lens and uses stainless steel hardware with insect-resistant gaskets to ensure long-term reliability. An optional Twist-Lock fitter provides tool-less, quarter-turn access for easy removal or replacement of the globe, simplifying maintenance and enhancing field serviceability. For utility applications, die-cast utility fitters are available with hinged, tool-less entry doors, optional terminal blocks, and GFCI receptacles. These options provide ease of wiring, auxiliary power access, and insect resistance while supporting quick servicing.
Serviceability is a core strength of the Palmetto series. The luminaire is designed for tool-less access to the driver compartment once the acorn is removed, making maintenance of the LED driver and surge suppressor straightforward. The lens can also be serviced easily in the field, further reducing downtime and simplifying long-term upkeep.
The lighting system is powered by high-output, vertically mounted chip-on-board (COB) LEDs. These high-brightness, RoHS-compliant LEDs are 100% recyclable and free from hazardous substances such as lead and mercury. They are engineered for longevity, delivering up to 100,000 hours of performance with greater than 70% of initial light output at 25°C, as verified through LM-80 and TM-21 testing. Correlated color temperature options range from 2700K to 5000K, with a minimum color rendering index (CRI) of 70. The vertical LED arrangement ensures full illumination of the luminaire, with controlled uplight to enhance vertical visibility. Light distributions are available in Type III, IV, and V, tested in accordance with IESNA LM-79 standards. For added control, an optional internal 120° house-side shield minimizes backlight, while an optional fixed dimming resistor board allows fine-tuned adjustment of light levels in 10 steps, ranging from 25% to 100% of output.
At the heart of the luminaire is a UL-recognized electronic driver, installed integrally within the housing. This high-efficiency driver operates at 50/60Hz, provides 0–10V dimming capability, and includes supplemental surge protection meeting IEEE/ANSI C62.41.2 standards. It is designed with a constant current DC output, a high power factor greater than 0.9, and a total harmonic distortion (THD) of less than 20%. Built-in safeguards protect against overload, overheating, and short-circuit conditions. Quick-disconnect electrical connectors make installation and servicing simple, while optional fixed dimming resistor boards provide field adjustability for consistent light output across multiple fixtures.
Control options enhance flexibility in operation. The luminaire may be equipped with electronic button photocells, twist-lock photocontrols, or shorting caps. Button-style photocells are mounted directly on the fixture, providing instant on/off response at calibrated light levels, while twist-lock controls are housed in the fitter with acrylic windows to read ambient conditions. Twist-lock versions are designed for compatibility with standard photocells only, ensuring simple and reliable dusk-to-dawn control. Optional 7-pin receptacles are available to support advanced control networks.
To complement its performance, the Palmetto series is offered with a robust six-stage polyester powder coat finish. This system exceeds AAMA and ASTM requirements for weatherability, gloss retention, and color stability, ensuring resistance to even the harshest environmental conditions. Standard colors include Black, White, Park Green, Architectural Medium Bronze, and Dark Bronze, while Sternberg’s Select palette offers antique-inspired finishes such as Old World Gray, Verde Green, Swedish Iron, Rust, Weathered Brown, Cedar, Old Iron, and Weathered Black. Each of these finishes adds a distinctive character to the fixture, blending modern performance with historic or decorative streetscape aesthetics. Two-tone and custom match options are also available for projects requiring precise color coordination.
Customization extends further through decorative enhancements. Optional cast decorative rings feature vertical slots and medallions, offered in gold, color-matched, or custom logo designs. Polished brass perforated rings provide another option, available in raw or painted finishes to complement the fixture’s architectural style. These details allow municipalities, campuses, and developers to create fixtures that reflect the identity of their space while maintaining high-quality illumination.
The A45LED Palmetto series is UL listed under UL1598 and CSA standards, making it suitable for wet locations throughout the United States and Canada. It comes backed by a seven-year limited warranty, underscoring the manufacturer’s confidence in its durability and performance. With the integration of Intellistreets® Technology, the luminaire can also incorporate advanced smart city features, including cameras, audio sensors, and monitoring capabilities, allowing communities to adapt to the future of connected infrastructure.
By combining a timeless Victorian design with cutting-edge LED efficiency, serviceability, control options, and smart technology compatibility, the A45LED Palmetto series represents a versatile and enduring choice for decorative street and area lighting. It balances heritage aesthetics with sustainable performance, making it equally suited for historic districts, municipal retrofits, college campuses, and urban redevelopment projects.
