The Millenia™ ML640 medium vertical tenon mount luminaire represents a breakthrough in modern area lighting technology, offering a bold new standard that blends urban design aesthetics with high-performance engineering. Its contemporary form is carefully crafted to transcend traditional lighting conventions by uniting architectural appeal and functional excellence, making it an ideal choice for commercial, institutional, and municipal applications. The luminaire is designed with flexibility in mind, offering a wide array of options to suit diverse project requirements, while its precision optical system ensures consistent and reliable performance in any environment.
Engineered for superior visual comfort, the ML640 can be equipped with the optional SoftVue™ lens, which reduces glare and enhances pedestrian experience by delivering smooth, visually comfortable illumination. The luminaire is UL listed to UL1598 standards and CSA C22.2 No. 250.0, ensuring compliance for use in both the United States and Canada, and is suitable for wet locations. With NightSky® friendly properties, select configurations meet U0 BUG rating standards to minimize sky glow and preserve dark sky conditions, making it a sustainable solution for urban and suburban installations.
The precision aluminum fitter is designed to ensure secure mounting, utilizing four stainless steel Allen-head set screws for attachment to a pole or tenon. It is engineered to slip fit a 3-inch OD by 3-inch tall tenon, providing reliable stability. Inside the luminaire, the UL-recognized LED driver is mounted securely for optimized performance and longevity. The high-efficiency driver operates at 50/60Hz and supports 0–10V dimming for flexible light control. Built with advanced protection features, it includes overload, overheat, and short-circuit safeguards as well as supplemental surge protection between line-ground, line-neutral, and neutral-ground connections in accordance with IEEE/ANSI C62.41.2 guidelines. The driver is designed to achieve a total harmonic distortion (THD) of less than 20% with a high power factor greater than 0.9, ensuring reliable and efficient operation.
The luminaire finish is achieved through a 6 Stage Polyester Powder Coat system, which provides a high-end appearance while delivering superior resistance to harsh environmental conditions. Each component undergoes rigorous inspection before shipment, ensuring a flawless finish that exceeds industry standards including AAMA 2604, AAMA 2605, ASTM D523, and ASTM D4214. The Urban Finish Palette further enhances the modern appeal, offering textured or matte surfaces with metallic flake finishes in Black Textured, Urban Gun Metal, Urban Bronze, Urban Silver, and Urban White. Custom finishes are also available, allowing the fixture to blend seamlessly with site-specific architectural elements.
The LEDs are mounted for optimal thermal transfer to the heat sink, maximizing longevity and efficiency. These LEDs are fully recyclable, RoHS compliant, and free of lead, mercury, and other hazardous substances. Their lumen maintenance is validated through IESNA TM-21 calculations based on LM-80 test data of no less than 6,000 hours, with in-situ testing by an NVLAP-accredited laboratory. The LEDs deliver a predicted lifespan of approximately 100,000 hours at 25°C with more than 70% of the initial light output retained. Standard configurations are available in 4000K CCT, with optional choices at 2700K, 3000K, 3500K, and 5000K, all maintaining a minimum color rendering index (CRI) of 70. Custom CCT or CRI requests can be accommodated upon consultation.
The advanced optical system of the ML640 incorporates individual refractor-type optics for each LED, ensuring precise and efficient light control. The luminaire can be configured for a range of distributions including Type II, III, IV, and V, in accordance with IESNA classifications, making it adaptable for various site lighting needs. Optical performance is validated through testing conducted per IESNA LM-79 standards.
For additional flexibility, the ML640 offers an optional Fixed Dimming Resistor Board (FDRB). This feature provides a numbered 10-step selector switch that enables fine-tuned light level adjustments in the field, ranging from 25% to 100% of the original output. This control is repeatable across multiple installations, ensuring consistent results. The FDRB is enclosed within a sealed composite material housing, protecting the components for the life of the product.
Backed by a 7-year limited warranty, the Millenia™ ML640 luminaire stands as a durable, efficient, and visually refined outdoor lighting solution. It combines architectural sophistication with state-of-the-art optical, electrical, and thermal performance, making it a trusted choice for those seeking both beauty and reliability in urban area lighting.
