• Lighting consumes up to 34% of all electricity in USA (source
Worldwatch Institute)
• Lighting consumes 19% of all electricity in the world (source IEA)
Lighting 19%
Other electricity 81%
Sustainability
• Revolution in lighting technology during the past 10-15 years.
• Approximately 2/3 of all lighting currently installed is based on older, less energy efficient technology (developed before 1970).
• Our current changeover rate to new lighting technologies is simply too slow: e.g. Street lighting 3% per year, Office lighting 7% per year.

White Light
Artificial light vs. natural daylight
Until now, only orange/yellow light (HPS, LPS) was efficient

Aesthetic Enhancement – Ambiance
• Effect closest to sun light
• Brings out the best in buildings and streets
• Best natural ambience - perceived as more authentic
• Most flexible color, works with all building materials
• Fresh and bright - lifts the atmosphere

Security – background facts
Various research shows:
•People fear for their safety around unlit areas
•White light reduces fear and crime and is economically attractive
Lighting Research Center, USA (2007)•White light is still preferred even when using only 1/3 of the light level (5 vs 15 Lux)
•At the same light levels, >80% of people feel safer with white light.
• Perception of safety is similar to HPS, when light level of white light is 30% lower.

Safety – Accident Prevention• Drivers see hazards more quickly and from
a greater distance – less stopping time
• Pedestrians see ongoing traffic earlier, and react accordingly
• Obstacles on footpaths seen more easily
