Hi, I would like to know the current practice in different country about the captions.

Street light - beside of sodium light, what is/are the application of induction lamp usually for? How is the use of LED light? Are they really energy saving OR deduct the luminance level and save energy? Will the heat loss of LED cause lower efficiency? What is the development of low level road light? Any use of fiber optics embedded on road surface? Risks in using road surface reflector? Any example of using present sensor in street light control?

Signage luminance - flood light is generally used? Any example in using LED light? Photovoltic panel / wind turbine as renewable enery of signage lighting? Successful usage of LED wash light? How about the use of flourscent light?

Tunnel lighting - any strategy in using flourscent light / flood light? Any measures in energy saving? Applications of light pipe / side emitted fiber optics?

Any reference webs / book recommended? Thanks for your patients and times.
