Lighting is an integral part of any home or commercial space. From what you can see from the humble lamp in your living room to the sweeping chandeliers of hotel lobbies, theres something special about the way light can both inspire and influence the people within it. Lighting is used to create atmosphere - from the soft yellow of a low lamp to the harsh white of office building fluorescents. Appropriate lighting can promote relaxation, concentration, and energy in individuals, and even affect their mood. In commercial spaces, light can add visual interest, suggesting certain kind of products or services. With more efficient lighting technologies it is now possible to save money and reduce energy consumption while still having the necessary illumination. LEDs, for instance, are now quickly replacing older technologies such as halogen and fluorescent, due to their low power consumption, long lifespan and environmentally friendly profile. Some modern buildings take advantage of natural light, both increasing natural visibility and cutting down on their electricity bill. Skylights and skylight tubes are just some of the technologies being increasingly used in modern day architectures, allowing daylight to reach places where the sun cant hit directly. All in all, lighting is more than just having a bright room. It is a key component in the sharing of feelings, emotions and atmosphere. It adds meaning and atmosphere to a space, making it into a place of refuge, stimulation, beauty and relaxation.
