Lighting is an important factor that affects our daily lives. We use different types of lighting for different purposes, from task lighting to provide us with clear view to decorative lighting to give our space some warmth and color. Having a right lighting is important for both our physical and mental health. For starters, the quality of light is important when it comes to lighting. Our eyes are sensitive to different qualities of light, and it can differentiate between warm, orangish light and cool, bluish light. Warm light tends to relax us and create a comfortable atmosphere for us, which is ideal in home and commercial spaces. Cool light in the opposite enhances our concentration and help us focus on work, which is suitable in work environments. In addition, lighting can also affect our emotions. For example, in a research conducted by Cornell University in 2015, participants were seated in an office or a restaurant with lighting either at their eye level or at the ceiling. The results showed that participants in the restaurant with the ceiling-level lighting reported higher level of pleasantness and relaxation than the ones with the eye level lighting. Finally, lighting can also enhance visibility in our daily lives. It is essential in many work environments such as chemists and dentists, who needs to see more details. Task lighting can be used to provide the necessary illumination to these workspaces to ensure that they are working safely. In conclusion, lighting can be used to create different moods and environments, and also provide visibility to those who needs it. It is thus important to choose a right lighting for your space to ensures that it meets your needs.
