The C0820-SD LED tunnel light is a robust and efficient lighting solution developed for tunnels, underpasses, subway corridors, and similar confined environments where stable, uniform, and glare-free lighting is essential for visibility and safety. It utilizes high-efficiency LED chips that produce bright, consistent output while maintaining low energy consumption and an extended lifespan. The luminaire employs an indirect lighting principle, where reflected light ensures uniform brightness without visible light points, minimizing glare, harsh contrasts, and visual fatigue for drivers and pedestrians.
Built for endurance and reliability, the C0820-SD features a housing constructed from high-strength aluminum alloy, combining rigidity and flexibility to withstand demanding environmental and structural conditions. Its enclosure ensures full protection against dust and water ingress under IP66 standards, while also providing excellent resistance to corrosion and rust. This construction grants the fixture a high degree of impact resistance and superior performance in environments exposed to humidity, vibration, and salt spray, making it ideal for both urban and industrial tunnel systems.
The fixture’s luminous flux ranges from 3,500 to 7,000 lumens, with power options from 26W to 360W. It achieves a luminous efficacy of 130 lm/W, maintaining an optimal balance between brightness and energy consumption. Operating on 220V AC, the C0820-SD offers a color temperature adjustable between 2700K and 5000K and a color rendering index (CRI) of ≥75, ensuring natural color visibility and visual comfort across tunnel surfaces. It maintains stable operation in ambient temperatures from -40°C to +55°C and relative humidity up to 95% (non-condensing), while delivering a service life of up to 50,000 hours, significantly reducing maintenance intervals and replacement costs.
A core innovation of the C0820-SD lies in its self-developed ceramic heat dissipation technology. This proprietary thermal management system efficiently channels heat away from the LED modules, ensuring consistent light output and preventing thermal degradation over time. This allows the fixture to achieve a lifespan approximately 50 times longer than traditional high-pressure sodium (HPS) lamps, supporting continuous operation in environments where maintenance access is limited or costly.
The light’s PC optical system, integrated with a ceramic pixel surface design, enhances light transmission and minimizes dust accumulation. This design maintains long-term optical clarity, reduces luminous decay, and lowers maintenance requirements by preventing the adherence of particulates that commonly affect performance in tunnel environments. The resulting light output is uniform, stable, and comfortable to the human eye, supporting improved visibility and driver safety without excessive glare.
With its robust aluminum alloy housing, high luminous efficiency, and optimized thermal and optical management, the C0820-SD LED tunnel light stands as a long-lasting, environmentally responsible solution for modern transportation and industrial infrastructure. Its corrosion resistance, waterproof structure, and consistent optical performance make it exceptionally well-suited for tunnels, roadway underpasses, subway systems, and gas station canopies where dependable, long-term lighting performance is critical for safety and operational reliability.
