The LuxTran LED tunnel light is a specification-grade luminaire developed for supplemental lighting in underpasses, tunnels, and other transition zones, providing uniform visibility from threshold to exit. Its versatile design allows for ceiling or wall orientation, enabling consistent performance in confined or elongated spaces. The fixture’s optical configurations are specifically optimized for tunnel lighting applications, offering precise control of light distribution to enhance safety and guidance. Built with a robust stainless steel chassis and marine-grade aluminum heat sinks, the LuxTran combines durability with thermal efficiency, ensuring long-lasting operation even in demanding environmental conditions. Backed by a 10-year limited product warranty, this luminaire provides reliability for infrastructure and transportation projects requiring continuous performance over extended lifespans.
The structural components of the LuxTran are fabricated from high-quality 16-gauge Type 304 or Type 316 stainless steel, constructed as one-piece, seam-welded enclosures with a 2B finish and passivated post-welding to resist corrosion. The doorframe shares the same robust stainless steel construction and includes lockable rotary latches (lock provided separately) and safety cables to secure the doorframe to the chassis. Mounting points are die-formed and welded from 14-gauge stainless steel, and custom mounting details can be provided to match specific tunnel structures. The luminaire accommodates wall or ceiling installation, with conduit entry located on the back, and mounting hardware is supplied by others. A one-piece extruded silicone gasket with molded corners ensures a reliable seal against moisture and dust ingress.
The LuxTran utilizes a serviceable high-brightness LED array with selectable color temperatures, maintaining a minimum of 65 CRI for clear, high-quality light output. Electrical input supports 120–277 VAC, 50/60Hz single-phase power, with less than 20% total harmonic distortion, a power factor above 0.90, and a minimum 90% driver efficiency. Standard 0–10V dimming allows adjustment from 10% to 100%, providing precise light control for varying tunnel environments. The electrical system is EMC compliant under FCC 47 CFR Part 15, Class B standards and passes IEC 61000-4-4 EFT and IEC 61000-4-5 Class 4 surge evaluations, ensuring robust operation under challenging conditions.
Thermal management is handled by Type 413 marine-grade die-cast aluminum heat sinks, electrically insulated from the stainless steel chassis and treated with coatings capable of withstanding either 1,000-hour or 5,000-hour salt fog tests per ASTM B117. This combination of materials ensures consistent thermal performance while resisting corrosion in harsh environments. The fixture is compatible with clear tempered glass or polycarbonate lenses, with optical distributions available in Type II, Pro-Beam, Type V-Narrow Round, and Type V Square formats, providing flexibility to meet specific lighting layout requirements.
The LuxTran LED tunnel light meets rigorous certification and performance standards. It is UL listed by Intertek Testing Laboratory for wet location applications, carries an IP66 rating per IEC 60598, and meets NEMA 4X requirements for corrosion and water resistance. The luminaire has undergone 3G vibration testing in accordance with ANSI C136.31 and passed ANSI C136.27-2012 qualification testing. Additionally, the fixture is compliant with the Build America, Buy America Act, ensuring eligibility for federal infrastructure projects. Photometric performance has been tested to the IESNA LM-79-08 standard by an ILAC/ISO17025 accredited laboratory, verifying its suitability for tunnel and underpass lighting with consistent, controlled light distribution.
