The ReluxTunnel calculation program has been developed for tunnel lighting experts. 

The program is based on the following standards:

• CIE 88:2004  "Guide for the lighting of road tunnels and underpasses", 
• CIE 140:2000  "Road lighting calculations" , 
• SLG 201:2005  "Richtlinien Öffentliche Beleuchtung – Strassentunnels, -galerien und –unterführungen "  
• DIN 67524-1:2008  "Lighting of street tunnels and underpasses Part 1: General quality characteristics and guide values" . 

Knowledge of these standards is essential in order to be able to assess the calculation results and plan the tunnel lighting on a practically-oriented basis.

You will need to purchase the corresponding licence before you can use the tunnel module.
