When thinking of lighting in a hotel, we should take into consideration the diversity of events that take place in a given space, be it a daytime conference or an evening wedding. Indeed, hotels now have a wide range of assorted facilities to manage: reception hall, restaurants, and corridors, hallways, guest rooms, and meeting spaces as well as service areas and recreation areas. It is critical to be able to adjust lighting, to change the colour of a space, and its ambiance from bright and lively to warm and inviting as some of these facilities operate 24/7, and the operating costs adds up quickly.
