Lighting Measurement LUMIOS MkIII

Luminance analyser A self-contained intelligent analyser that measures the level of brightness or luminance created by natural light around tunnel portals. When integrated with a managed tunnel lighting system, its measurements ensure that drivers’ visual perception is maintained day and night, avoiding sudden variations and potential “black hole effects” when entering and [...]
