Lighting is an integral part of our daily lives. It is used to brighten up our homes, classrooms and outdoor environments. Lighting provides us with a sense of security and helps us to get around when the sun sets. It also affects our moods, productivity, circadian rhythms and our overall health. The most common type of lighting used in our homes is artificial lighting, also known as electric lighting. It comes in many different forms such as bulbs, spotlights and flood lights. LED lighting is becoming more popular due to its efficiency, longevity and the variety of options available, such as dimmable and color changing LEDs. For outdoor environments, natural lighting, such as sunlight, can be used to brighten up walkways, gardens and other areas. This type of lighting is attractive and eco-friendly because it does not require any electricity. Solar lighting is a great way to incorporate natural lighting into outdoor areas, as it uses the power of the sun to produce light. Natural lighting and electric lighting should be used together in a balanced manner. Too much of either can be detrimental to our health and the environment. Selecting the correct type of light and the right amount of illumination is important for creating a well-lit and comfortable environment.
