Advantages of HLG
• Lamp and Luminaire are separated
• Light Sources with high luminous flux can be used
• Maintenance is simplified, thus reducing costs
• Light (artificial and daylight) can be transported over
a long distance
• Light can be coupled out uniformly

The lighting should
• supply the staircase with a sufficient amount of light to use the staircase in a quick and safe way
• give good modelling to the people, meeting in the staircase
• provide good adaptation to the light quality in the connected rooms, which are illuminated by daylight (at daytime)
