Lighting, is one of the most important elements of our everyday lives. It can have a huge impact on the atmosphere of our homes and on how productive we are in our work. Whether its natural sunlight or artificial lighting, the kind of lighting you choose can have a lot of influence on your life. Natural lighting or daylight is considered to be the best light for productivity and creative thinking. Being exposed to natural light helps regulate your sleep/wake cycles and can reduce feelings of depression. Studies have also shown it increase productivity levels.Having plenty of windows in your office or home will give you natural light during the day, and you can install blinds or tint the window to reduce glare in the hotter months. Artificial lighting or electric light is something we cannot do without. This is especially important during winter periods where daylight is scarce. Many types of electric light are available for you to use in your home or office. The most common ones are LED, Fluorescent, Halogen, and Incandescent lamps. LED lights are the most energy efficient and they generally last much longer than other light types. Halogen bulbs produce high quality white light but are not as energy efficient as LED luminaires. Incandescent bulbs are low efficiency and should not be used for long periods. In summary, the kind of lighting you choose will have an impact on the atmosphere in your home or office and on your productivity. Natural sunlight is the best for concentration and creativity, but electric lighting should be the main source of lighting in the darker months. Use LED lighting for improved energy efficiency and longer lasting bulbs.
