Lighting is the use of light to achieve a practical or aesthetic effect. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight. Daylighting (using windows, skylights, or light shelves) is sometimes used as the main source of light during daytime in buildings. Different types of lighting have different characteristics; in particular, different colour temperatures will appear differently under different lighting conditions. This can affect how a room looks, what activities are best done there and how people in the space feel. Adequate lighting can in fact improve the mood of individuals working in a particular space. The correct lighting can also help to reduce glare and create visual comfort, which can be enough to make a space workable for a longer period than it could under normal lighting conditions. Furthermore, lighting can also serve to highlight particular features of a room or space. Uplighting is one such technique, which uses strategically placed recessed or track lighting to show off the features of a room or space, such as an impressive piece of furniture, artwork or architectural feature. Wall washing is a similar technique, which provides a focused light that washes up the walls of a room, to draw in attention to specific features. The use of proper lighting can create a beautiful environment where people can work, relax and enjoy themselves in. Proper lighting can also reduce energy consumption by using more efficient lighting technologies such as LEDs and CFLs. Improper lighting can be uncomfortable, and even dangerous, so its important to take lighting seriously. With careful thought and consideration – and of course, the help of an expert – proper lighting can transform any space into something truly special.
