The Arc™ LED track light with TEK adapter combines a slim, contemporary aesthetic with exceptional optical efficiency and performance. Its ultra-efficient optical system is engineered to maximize light output while minimizing fixture depth, creating a refined and unobtrusive profile ideal for modern environments. Delivering the light output and distribution comparable to a 60–75W PAR30 halogen lamp, the Arc LED track head consumes only about 20% of the energy and provides a rated life of 50,000 hours, making it a reliable and efficient choice for long-term use.
Available in 2700K, 3000K, 3500K, and 4000K color temperatures, the Arc LED offers standard 80 CRI and high 90 CRI options, as well as optional SpectralWhite color/white enhancing versions with 90+ CRI for superior color rendering. The SpectralWhite technology enhances color vibrancy and makes whites appear naturally brilliant, ensuring visually appealing results across retail, gallery, and architectural applications. A louvered lensholder option further optimizes visual cutoff and reduces glare, while an optional hexcell louver accessory can be added at any time for additional visual refinement.
The fixture’s die-cast aluminum housing provides excellent thermal management, ensuring consistent performance and longevity with an average of 70% lumen maintenance at 50,000 hours of operation. The Arc LED maintains a fashionable yet understated look with a smooth finish available in white, black, or silver, allowing it to complement virtually any décor. A high-performance LED array ensures reliable output and color consistency within a 3-step MacAdam Ellipse, guaranteeing precise chromaticity and uniformity across installations.
The driver is discreetly concealed behind the LED light engine housing, minimizing the overall fixture footprint while maintaining quiet and reliable performance. An insulating air gap between the driver and light engine enhances thermal efficiency, extending component lifespan. The driver supports dimming through reverse phase electronic low voltage (ELV) dimmers and includes integral overcurrent and short-circuit protection. As a solid-state electronic, Class 2-compliant system, it is FCC-certified to Part 15 Class B EMI standards and built for an operating life exceeding 50,000 hours.
Optical flexibility is a hallmark of the Arc LED design. The proprietary, interchangeable polycarbonate lenses allow users to select between two factory-configured beam spreads, with additional accessory lenses available for field changes. The standard lensholder maintains a low-profile design, while the optional hexcell louver version improves visual comfort and reduces brightness from high angles. Both versions retain the lens securely and are interchangeable for quick adaptation to varying lighting needs.
For maximum compatibility, the Arc LED includes a universal track adapter suitable for Juno Trac-Master 1-circuit or 2-circuit systems, Trac-Lites track, monopoints, and other specialized mountings. The adapter is UL-recognized for use with ConTech® LT Series tracks and incorporates copper alloy contacts that ensure consistent electrical performance without arcing. A spring-loaded positive latch secures the fixture to the track, while patented polarity arrows and an on/off switch streamline installation and service. The two-position power contact enables seamless use in two-circuit applications.
Alternate adapter configurations further expand system versatility. The TEK adapter ensures correct orientation through integrally polarized construction and includes a rotary circuit selector and individual on/off switch for servicing. GTYPE, HTYPE, and LTYPE adapters provide compatibility with other commercial and decorative track systems, with two-position power contacts available where applicable.
The Arc LED track head offers 360° horizontal coverage and up to 95° vertical aiming capability, allowing precise directional control for accent or general lighting. Rated for dry location use, it is UL and cUL Listed, DLC qualified (excluding accessories), and proudly assembled in the United States. It meets the requirements of the Buy American Act (BAA), Buy America regulations (DOT), and the Build America, Buy America Act (BABA), ensuring compliance with federal procurement standards.
Combining architectural elegance, versatile optical performance, and reliable American-made quality, the Arc LED track light stands as a contemporary and energy-conscious solution for professional-grade lighting applications.
