Lighting is the use of artificial light to increase visibility in order to create or enhance an atmosphere. It is probably one of the most important aspects of any environment. In a workplace or school, for example, lighting is used to improve visibility and reduce fatigue for longer periods of work. At home, lighting can be used to create a cozy atmosphere or a bright and energetic one. The type of lighting used can drastically affect the atmosphere of a room or building. Natural light, for example, can be used to create a calming atmosphere while artificial light can be used to create a more vibrant and energetic atmosphere. Ambient lighting can also be used to highlight specific design elements in a room or to create contrast between different areas. There are many different types of light sources available for lighting. Incandescent bulbs may provide soft, romantic lighting, while halogen lamps are very energy efficient and provide bright, direct lighting. Fluorescent bulbs are available in many colors and provide a cost-effective option for lighting large areas. LED bulbs offer great energy efficiency, long life-span, and custom colors for lighting effects. Lighting can also be used to create a mood or make an aesthetic statement. Uplighting can be used to highlight artwork or sculptures, while downlighting can be used to create a more dramatic or moody atmosphere. Accent lighting can be used to draw attention to certain areas of a room or to illuminate objects on shelves. Lighting is an important part of any environment and can drastically affect the atmosphere of a space. It is important for people to take time to select quality lighting to ensure that the atmosphere they are creating is the one they desire.
