The Dart suspended direct/indirect LED luminaire is designed to deliver high performance in a sleek and unobtrusive profile, making it an excellent choice for spaces with lower ceilings and environments where ceiling uniformity is essential. Its thoughtful optical design ensures both visual comfort and architectural harmony. At the heart of Dart’s performance is the Gradient Optic, a precision-engineered saw tooth reflector that diffuses the edges of the indirect distribution. This innovation eliminates harsh cutoff lines on vertical surfaces while simultaneously directing light downward through the lens and reducing brightness directly above the luminaire. For installations where fixtures are mounted near walls, the optional Beam Smoothing Diffuser offers an additional level of softening, ensuring smooth and consistent illumination across the space. The MicroGlow prismatic lens adds further control of brightness and cutoff, enhancing comfort in workplaces, classrooms, and other environments where balanced lighting is critical.
Despite its petite form factor, Dart integrates advanced lighting technologies that make it a powerful solution for modern spaces. With Right Light™ technology, the luminaire provides multiple standard output levels, ranging from 750 to 1250 lumens per foot, ensuring reliable and consistent performance across applications. Designers can select from several factory-programmable driver settings to fine-tune energy consumption and light levels without the need to recalculate designs, offering both flexibility and efficiency. Standard color temperatures of 3000K, 3500K, and 4000K with a CRI greater than 80 ensure accurate color rendering, while the LED system’s 3-step MacAdam ellipse (3SDCM) consistency guarantees uniform light quality. Robust thermal management and replaceable LED boards and drivers contribute to long-term sustainability, with lumen maintenance reported at L70 for 60,000 hours and calculated at up to 130,000 hours.
The construction of Dart emphasizes durability and clean aesthetics. It features a one-piece 22-gauge steel housing with steel end caps that attach flush for a seamless appearance. When used in row installations, internal brackets create hairline joints for a continuous, uniform look. Each luminaire is available in 4', 6', and 8' lengths with weights of 10, 16, and 21 pounds respectively. Suspension mounting options include 24", 48", and 96" cables, with additional configurations available for plenum and sloped ceiling applications. The finish is achieved with a high-quality polyester powder coat applied over a multi-stage pre-treatment process, available in Titanium Silver or Matte Satin White, with canopies finished to match.
Dart is designed to integrate seamlessly into connected building systems, making it a future-ready lighting solution. It supports a wide range of wired and wireless controls, including 0-10V dimming to 1% or 10%, DALI protocols, and Lutron Hi-Lume EcoSystem compatibility. Advanced options include Wattstopper fixture sensors (low- or high-density), Encelium CLM connected lighting modules, and WaveLinx Pro wireless integration. These systems enable advanced capabilities such as daylight harvesting, occupancy sensing, HVAC system integration, and personal controls, all reconfigurable through software to adapt as project needs evolve. With these capabilities, Dart not only enhances occupant comfort but also helps reduce energy usage and operational costs.
Electrical performance is equally robust, with a standard 120–277V constant current driver and power factor greater than 0.9. For emergency preparedness, all models can be equipped with a 12W battery providing 90 minutes of operation, with the Beam Smoothing Diffuser supplied as standard in these configurations. Emergency circuits integrate easily with UL924-compliant devices, ensuring code compliance and peace of mind. Luminaires are UL and cUL listed for dry and damp locations, making them suitable for a variety of indoor applications.
Ultimately, the Dart suspended LED luminaire combines high-performance optics, versatile output options, and seamless system integration in a refined, minimal form. It is a discreet yet powerful lighting solution that not only saves energy but also contributes to healthier, more productive environments where comfort, efficiency, and visual quality are equally valued.
