Lighting plays a key role in our daily lives, and is of vital importance in both home and work. Proper lighting not only gives us illumination, but also can impact our mood and well-being. Good lighting in the home can encourage relaxation and focus, as well as making tasks such as reading and cooking easier. The placement of light sources throughout a house has the potential to both improve functionality and create atmosphere within a room. Natural lighting can help to save energy costs, while adding character and warmth to a home. At work, good lighting is vital for the productivity and safety of employees. With efficient lighting, tasks can be performed with greater speed and accuracy. Poor lighting can result in eye strain, fatigue and mistakes, so it is important that the workspace is well-balanced and even. Scientifically designed lighting fixtures can ensure an optimized lighting environment in which employees can remain engaged and energetic throughout the day. Lighting is an integral element of modern life, and proper lighting can improve our productivity, save energy and enhance atmosphere throughout our daily lives.
