The A65LED Princeton Series is a stylized Victorian acorn luminaire that blends traditional elegance with modern LED performance. Featuring a decorative cast aluminum fitter and a high-efficiency prismatic acrylic acorn, the fixture is topped with a cast aluminum four-vane finial for a distinguished and timeless appearance. This combination makes it ideal for streetscapes, campuses, municipal projects, and architectural environments that require both historic styling and advanced illumination.
Built for durability, the luminaire’s sand-cast fitter is constructed from heavy-wall, low-copper aluminum alloy for enhanced corrosion resistance and tensile strength. It includes an 8.5-inch inside diameter opening that securely attaches to the 8-inch lens neck with stainless steel Allen-head set screws and an insect-resistant gasket. Utility fitters are available in die-cast aluminum with hinged, tool-less entry doors, providing easy access to internal components. These utility versions can also be equipped with optional terminal blocks, twist-lock photocontrol receptacles, and GFCI outlets for auxiliary power. A top-mounted driver plate allows for quick tool-less removal using finger latches. For added convenience, the optional twist-lock fitter employs a quarter-turn mechanism for effortless acorn removal and replacement, simplifying maintenance.
The Princeton Series is powered by vertically mounted, high-output chip-on-board (COB) LEDs, which provide full luminaire illumination with controlled uplight for enhanced vertical visibility. These LEDs are RoHS compliant, recyclable, and free from hazardous materials such as lead or mercury. Designed for longevity, they achieve a projected lifespan of up to 100,000 hours, maintaining over 70% of initial light output at 25°C. Color temperature options range from 2700K to 5000K, with a minimum color rendering index (CRI) of 70, ensuring versatility across a wide range of applications. Light distribution patterns are available in Type III, IV, and V, tested in accordance with IESNA LM-79.
At the heart of the fixture is a high-efficiency, UL-recognized electronic driver installed integrally within the housing. This constant-current driver operates at 50/60Hz, delivers a high power factor greater than 0.9 with total harmonic distortion below 20%, and includes built-in protections against overload, overheating, and short circuits. It also features supplemental surge suppression in compliance with IEEE/ANSI C62.41.2 standards. For greater flexibility, the driver supports 0–10V dimming, while an optional fixed dimming resistor board provides field adjustability in ten steps, allowing precise control of light levels from 25% to 100% output. Quick-disconnect connectors simplify installation and servicing.
Control options for the A65LED Princeton Series include button-style electronic photocells, twist-lock photocontrols, and shorting caps. The button photocell provides instant dusk-to-dawn operation, while twist-lock versions, mounted in the fitter with acrylic windows, ensure reliable response to ambient light levels. Twist-lock units are designed for compatibility with standard photocells only and are warranted for six years. An optional seven-pin receptacle enables integration into advanced control networks.
Mounting configurations are highly versatile, allowing the Princeton Series to be adapted for a variety of settings. Options include wall mount, post-top, arm-mounted, mid-mount, pier base, and multi-arm arrangements ranging from dual to four-arm setups at various angles. A wide selection of fitter options further expands compatibility, including standard slip-fitters, decorative oak-leaf or art-deco styles, low-profile fitters, and heavy-duty utility versions. Each fitter is sealed with a one-piece gasket to resist insect intrusion and is secured with stainless steel hardware.
The fixture is also available with Intellistreets® Technology, offering an integrated platform for smart city applications. With the ability to support cameras, audio sensors, and environmental monitoring, Intellistreets® transforms the Princeton Series into a future-ready luminaire that provides both illumination and connectivity for modern infrastructure needs.
A wide variety of decorative enhancements are available to personalize the fixture. Cast aluminum rings with vertical slots and medallions can be finished in gold, color-matched, or customized with logos. Brass perforated rings are offered in raw or painted finishes, adding further design flexibility. These details allow municipalities, developers, and campuses to create fixtures that complement their architectural identity while maintaining high-quality illumination.
The exterior of the luminaire is finished with Sternberg Lighting’s six-stage polyester powder coat paint system, which exceeds AAMA and ASTM requirements for durability, gloss retention, and weatherability. This advanced coating process ensures long-lasting performance even in harsh environments. Standard finishes include Black, White, Park Green, Architectural Medium Bronze, and Dark Bronze. The Sternberg Select antique-inspired palette offers unique finishes such as Old World Gray, Verde Green, Swedish Iron, Weathered Brown, Cedar, Old Iron, and Weathered Black. Each of these adds character and historic charm, while two-tone and custom match options are available for projects requiring precise coordination.
The Princeton Series is UL listed to UL1598 and CSA standards, making it suitable for wet locations throughout North America. It comes with a seven-year limited warranty, underscoring Sternberg Lighting’s confidence in the fixture’s reliability and performance. With its blend of timeless Victorian design, advanced LED efficiency, versatile mounting and control options, decorative enhancements, and smart city readiness, the A65LED Princeton Series offers a flexible and enduring solution for decorative street and area lighting.
