Lighting is one of the most important elements in our lives whether its the sun, moon, or artificial lights. It illuminates our world and makes it possible for us to receive and transmit information. In fact, the presence of lighting can be considered a major factor in our ability to perceive the world around us in the way that we do. Lighting affects our lives in many ways: it impacts our moods, our motivation, our productivity and creativity, and even our health. A dark room can leave us feeling exhausted and unmotivated while a bright, well-lit space can help us feel energized and productive. In certain cases, certain types of lighting can even impact our physical health, as studies have found that exposure to natural sunlight can reduce the risk of certain diseases such as Vitamin D deficiency and depression. Lighting can also be used in a creative way to express art, film, photographs, and other forms of media. Different colors, angles, and types of lighting can add a certain aesthetic and mood to a scene. In theater, lighting plays a large role in how a production looks and plays out. Dim lights may give a scene a feeling of mystery while bright lights can exude a sense of energy. Lighting can be a deceptive element. While one can safely assume that darkness will always result in a lack of visibility, oddly enough, too much light can also do that. Too much lighting can actually create glare, which can cause difficulties with visibility. When designing lighting fixtures, architects and lighting designers have to be careful to find the perfect balance between enough and too much light. In short, lighting is an essential part of our lives and has a powerful impact on our well-being, our productivity, our creativity, and even our physical health. From the sun to the moon to stage lights, each type serves a unique purpose and has its own impact.
