The LuxTran linear LED tunnel light is a specification-grade luminaire designed for continuous or discontinuous row installations in underpasses, tunnels, and other transition zones. Its integral driver construction enables consistent performance and simplified electrical integration, while the tool-less access and removal of the light engine and optical assembly from the raceway enclosure provide ease of maintenance and quick serviceability. The luminaire accommodates both ceiling and wall orientations, with optical configurations optimized specifically for tunnel lighting applications to deliver controlled, uniform light distribution across critical zones. This product is backed by a 10-year limited warranty, ensuring long-term reliability in demanding environments. Lens options include clear tempered glass at .187 inches or clear polycarbonate at .125 inches, allowing for flexibility depending on environmental conditions and project requirements.
The chassis and light engine housing are built from high-quality stainless steel. The raceway and doorframe are constructed from 18-gauge Type 304 or Type 316 stainless steel with one-piece, seam-welded construction, 2B finish, and post-welding passivation for corrosion resistance. Internal marine-grade aluminum heat sinks provide thermal management, while stainless steel safety cables secure the light engine within the raceway. Lockable rotary latches, constructed of matching-grade stainless steel, ensure safe and secure access during maintenance, with locks supplied separately. A one-piece extruded silicone gasket with molded corners seals the luminaire, protecting against moisture and contaminants. Raceway mounting hardware is provided by others, and the system accommodates 14-18 AWG DC branch conductors for up to six circuits within a single raceway. Provided wire taps and two-position electrical connectors allow for quick connection and disconnection of the light engine from the DC supply. The ambient temperature rating ranges from -40°C to 50°C, making the LuxTran suitable for extreme tunnel environments.
Electrical performance is delivered through a serviceable high-brightness LED array, with a minimum 65 CRI and selectable color temperature options. The fixture supports 120–277 VAC input with a high-power-factor, constant-current driver, and 10–100% dimming using a compatible 0–10V current-sink dimmer. An integral surge protector is standard, providing robust protection against electrical transients. Optical performance is achieved through Type II or Type V Square distributions, paired with either clear tempered glass or polycarbonate lenses, ensuring controlled and consistent light patterns suitable for tunnel and transition-zone applications.
Accessories enhance installation flexibility and system integration. End-mount junction boxes attach to end-located luminaires within continuous or discontinuous runs and allow for connection via ¾” or 1” trade-size sealed conduit, including two conduit entry points for left/right entry or multiple-row pass-through installations. Mid-mount junction boxes provide similar connectivity for luminaires positioned mid-run, and run termination covers are available to complete the end of continuous or discontinuous luminaire runs.
The LuxTran linear LED tunnel light is certified to UL standards for wet locations by Intertek Testing Laboratory, with an IP66 rating per IEC 60598 and NEMA 4X compliance for corrosion and water resistance. The luminaire is 3G vibration tested according to ANSI C136.31 and meets ANSI C136.27-2012 qualification standards. Photometric performance has been verified to the IESNA LM-79-08 standard by an ILAC/ISO17025 accredited laboratory, ensuring precise, reliable, and uniform light distribution for tunnel and underpass applications. Custom mounting details are available to adapt to specific tunnel structures, allowing for seamless integration into complex infrastructure projects.
