Lighting refers to the use of artificial light sources to provide the necessary illumination, whether in the home, in a commercial or industrial setting, or in public spaces. Lighting can give rise to a pleasant and safe atmosphere in certain living and working areas. The basics of lighting can range from the simplest of single light bulbs to the most complex lighting system design. The aim is to ensure that lighting has the correct intensity and colour for its intended purpose. It is important to consider the area or space lighting is being used in, in order to ensure that not only is the illumination correct, but also the design aspect of lighting. Good lighting can help to enhance the visual appeal of any setting. Lighting technology has advanced greatly over the years, with a great range of lighting varieties, types, and products now available for use. LED lighting is the most popular these days,due to its energy efficiency. Not only does LED lighting use less energy than traditional types, it also has a longer life. Other types of lighting include incandescent, fluorescent, and halogen. When selecting a type of lighting, it is important to consider the size, colour, brightness, and ambience of the area being lit. Safety is always a priority when it comes to lighting, and should not be overlooked. Consideration must be given to the position of lighting fixtures, and the possible effects of their use on the surrounding areas. For example, indirect lighting can be used to create a subtle glow. On the other hand, too much light may be too harsh and may cause glare or shadows. Whether in a home or an industrial setting, good lighting is essential. It can help to create the perfect atmosphere, be it calming, invigorating, inspiring, or calming. Lighting can also be used to make a dramatic visual impact in any setting, and should be used in conjunction with other design elements.
