Lighting is a form of energy that is used in a wide variety of applications in our daily life. The sun is the main source of light, but there are many other artificial sources of light including electric lamps, candles, bonfires, and lanterns. Lighting can be divided into two types general lighting and task lighting. General lighting is used to provide illumination to a room or an area. Examples of general lighting include ceiling lights, wall lights, and recessed lighting. Task lighting serves a specific purpose, for example, reading, studying, cooking, and crafting. It is usually more focused and intense than general lighting and can often be adjusted to provide more light in specific areas. Fluorescent lights, table lamps, floor lamps, and desk lamps are all examples of task lighting. Lighting can also be used to create a certain mood or atmosphere. Different colors, brightnesses and hues of light can affect the emotion and experience of a space. For example, soft yellow lighting can provide a warm and cozy atmosphere while bright white light can create an energizing effect. To save energy and money, consider using natural light whenever possible. Take advantage of skylights, windows, and natural ventilation. Make sure to also use energy-efficient bulbs in all lighting sources. With thoughtful lighting choices, you can reduce energy costs and create a better environment.
