Lighting exists just about everywhere. It's in our homes, workplaces, swimming pools, streets, vehicles and patios, etc. It often goes unnoticed, but lighting comes from many different sources. The term lighting basically refers to any device, or technique, that is used for illumination. This covers man-made light sources such as lamps or flashlights; however natural lighting is also common in the form of windows and skylights. There are several types of lighting as we can get from electric lights, gas or oil lamps, and candles. Lighting is also a form of furnishing, and people often incorporate a decorative and creative style into their lighting, both indoors and outdoors. Different shades and levels of lighting are often used and colored lighting can be very prominent. Lighting is often installed in floors, on walls and in ceilings, and can be free-standing in the form of a lamp or spotlight.
