The Trac-Master LED track light with HTEK adapter presents a refined interpretation of a traditional aesthetic, blending timeless simplicity with modern LED technology. Operating at just 11 watts, this state-of-the-art luminaire delivers up to 1,249 lumens—representing up to 80 percent greater efficiency than comparable halogen fixtures—while maintaining a rated life of 50,000 hours. It is available in color temperatures of 2700K, 3000K, 3500K, and 4000K with options for 80 or 90 CRI. The optional SpectralWhite versions enhance both color and white tones with a 90+ CRI, producing vivid, naturally brilliant results ideal for environments demanding superior visual quality.
At the heart of the fixture lies a high-performance LED array engineered for reliability, color consistency, and long-term stability. Its chromaticity range remains within a tight 3-step MacAdam ellipse, ensuring uniform visual appearance across installations. The SpectralWhite versions, offered in 3000K and 3500K, provide exceptional color fidelity that enriches every hue. Complementing the precision light source, an all-metal housing and custom-designed heat sink ensure excellent thermal management, maintaining a minimum of 70 percent lumen output after 50,000 hours of operation. The vertically mounted driver assembly is housed in a compact side-mounted enclosure that minimizes the fixture’s overall footprint, while an insulating air gap between the LED engine and driver optimizes thermal performance.
The optical system employs a precision-engineered TIR lens to achieve uniform and controlled beam distributions. Options include spot, narrow flood, flood, and wide flood configurations, each delivering consistent beam quality across the field. The integral bayonet-mount accessory holder allows easy conversion between beam spreads and accommodates one accessory if desired, enhancing flexibility for varied lighting applications. The fixture provides full 360-degree horizontal rotation and more than 90 degrees of vertical aiming, allowing precise directional control in any architectural setting. Available in white, black, or silver finishes, the luminaire complements a broad range of interior design styles while maintaining a clean, understated appearance. It is UL/cUL listed, ENERGY STAR® qualified, and suitable for dry locations, ensuring compliance with major safety and performance standards.
Expanding beyond the 11W model, the Trac-Master vertical cylinder LED fixtures also include a 16W version, both capable of producing efficacies up to 114 lumens per watt. They are compatible with all Juno line-voltage tracks and adapter accessories, and also offered in WarmDim versions that replicate the warm tonal shift of halogen dimming from 3000K to 1800K. Each fixture’s construction emphasizes longevity and performance, with a concealed heat sink, extruded aluminum driver housing, and passively cooled design that eliminates moving parts and ensures quiet, maintenance-free operation. The concealed wiring preserves a clean aesthetic, while the fixture’s proportion and finish convey a refined, architectural quality.
The LED technology maintains tight chromatic consistency within a 3-step MacAdam ellipse for static white versions and an even more precise 2-step range for WarmDim models. Standard versions offer a minimum of 80 CRI, while high-CRI models achieve 90 CRI with R9 values exceeding 50 for rich red rendering. SpectralWhite versions elevate visual impact by making whites more brilliant and colors more saturated. The solid-state electronic driver operates quietly and efficiently, Class 2 compliant with integral overcurrent and short-circuit protection, and rated for FCC Part 15 Class B. The fixture is dimmable with high-quality reverse-phase ELV dimmers approved by Juno, ensuring smooth and flicker-free dimming performance.
The Trac-Master system integrates seamlessly with multiple track adapter configurations. The universal Juno track adapter is compatible with Trac-Master one- or two-circuit systems, Trac-Lites, monopoints, and special mountings, as well as ConTech LT Series tracks. It includes copper alloy contacts for precise connection, a true electrical ground, an on/off switch, and embossed polarity arrows for easy alignment. The alternate TEK/HTEK adapter supports both Juno TEK and HTEK track systems, with polarized construction preventing incorrect installation, a rotary circuit selector for easy switching, and an integral on/off switch for convenient servicing. Additional adapter options—GTYPE, HTYPE, and LTYPE—extend compatibility with track systems from Lithonia and other manufacturers, ensuring broad installation flexibility across various lighting infrastructures.
Every detail of the Trac-Master fixture is purposefully refined. The die-cast aluminum accessory holder integrates seamlessly with the fixture body through a precision bayonet mount. A full range of optical accessories and field-changeable optics allows customization of beam performance for gallery, retail, or accent environments. The fixture achieves complete 360-degree rotation and greater than 90-degree tilt adjustment, offering full directional flexibility.
The Trac-Master LED track light meets rigorous quality and performance standards, including UL and C-UL listings. High-CRI and SpectralWhite versions comply with California Title 24, Part 6 high-efficacy requirements. Each unit is union-made and assembled in the United States, qualifying under major U.S. government procurement regulations such as the Buy America(n) Act (BAA), Build America, Buy America (BABA), and DOT Buy America provisions. This certification ensures the fixture meets domestic manufacturing standards and supports projects requiring compliance with federal sourcing requirements.
Combining timeless styling, reliable LED technology, and precise optical performance, the Trac-Master LED track light with HTEK adapter provides a versatile, high-quality solution for architectural and accent lighting applications across commercial, retail, and residential environments.
