- Daylight detection
Daylight detection
Artificial lighting which responds to the natural light conditions.
- Constant illuminance
Constant illuminance
A function designed to produce correct light levels for the duration of the maintenance period.
- Task-scene setting
Task-scene setting
Allowing the user to set scenes and adapt the lighting to different tasks.
- Timed off
Timed off
Automatic cut-off can be installed to turn all lights off during unoccupied hours.
- Task lighting
Task lighting
Ensuring light is concentrated on the task provides the required high levels of illuminance while using minimal energy through less light loss in ancillary areas.
- Zoning of lighting
Zoning of lighting
Careful selection and arrangement of lighting on key sections of the slope maximises lighting impact whilst minimising energy use on lighting in areas of lesser importance.
- Maintenance schedule
Maintenance schedule
Maintenance must be performed in response to product age, performance and environment.
- Waste light
Waste light
Precise optical control and luminaire aiming minimises spill light, so no energy is wasted lighting the wrong area.
- Reflectance
Reflectance
Taking advantage of light which is reflected from the surface within the space.

Results of actions can be quickly seen as increased or decreased energy use to encourage responsible energy consumption.
Ski resort improves world championship prospects with Mundial floodlights
Åre is an alpine ski area and the largest mountain sports resort in Sweden. Located at the foot of Areskutan, a mountain 1,420 meters above sea level, it was host to the World Cup Championship in 2007 and named the "World's Top Ski Resort" in 2009 by the British travel magazine Condé Nast Traveller.
The Störtloppet ski slope is Sweden's most fierce and dangerous. It has a total length of 2,912 feet with a vertical drop of 841 metres. To bring it up to world class standards and meet television broadcast requirements, 350 Mundial HQI-TS 2000W floodlights were specified to illuminate 1,308 feet with a vertical drop of 416 meters.
Producing a light level of 1,000 lux, Mundial is mounted at a height of 15m and can be set in three different lamp positions. It also features a spun circular reflector with baffle for asymmetrical lighting distribution. By minimising glare, light spill and upward light, Mundial effectively prevents obtrusive light and light pollution. This is especially important for preserving the local environment.
Nalle Hanson, Arena Manager at SkiStar Åre says: "With the new lighting, we can now run evening competitions throughout the winter. The last winter women's World Cup competitions were in fact run with the new lighting and both the competitors and the television broadcasting company were very happy with it. The lighting level of 1,000 lux is particularly crucial for managing the broadcasting requirements.
"Aside from the lighting, SkiStar is also very satisfied with the cooperation with Thorn."
