Tunnel and Underpass Lighting
One of the greatest challenges of tunnel and underpass lighting systems is their ability to support drivers’ visual perceptions—both day and night—from the point of entry through to the point of exit. Effective tunnel and underpass lighting, therefore, requires consistent light levels throughout the structure for safe passage.
These are also highly corrosive environments requiring sealed and durable luminaires. Due to heavy traffic and fluctuations in weather and climate, tunnel fixtures are continually exposed to water, dirt, road salt, exhaust fumes, brake dust and other corrosive agents.
