Brief Introduction
The HY-LXP21E measures the level of illuminance within the tunnel bore to ensure interior illumination levels are being continuously maintained in order to affect safe lighting conditions for drivers. Illuminance, or incident lighting, determines the amount of light that covers a specific surface or area within the tunnel.
Designed specifically for the tunnel environment, the HY-LXP21E continuously measures cosine corrected planar illuminance within the tunnel thus allowing elimination of directional error. The HY-LXP21E measures the illuminance over a standard range of 0 - 20,000 lux.
