Lighting is a very fundamental part of our everyday lives. With advancements in lighting throughout the years, efficient lighting has become a necessity in contemporary times. Lights provide us with visibility and illumination for many different tasks – be it inside the home, for work, when reading and studying, or simply just for leisure. Lighting of any form does not only provide visibility and illumination, it also has the psychological and physiological effect of enhancing mood and performance. For example, natural lighting has the psychological effect of inducing a person's feeling of compassion and peacefulness. This is in contrast to artificial lighting such as fluorescent light, which many consider to be harsh and uninviting. Aside from providing visibility and having psychological effects, lighting does have its practical uses too. Today, saving on energy costs has become increasingly important, and efficient lighting solutions are one of the most beneficial solutions for energy conservation. LED lighting with dimmer feature helps to keep energy costs low, as it reduces energy consumption by around 50%. In addition, LED lighting is cool to the touch, and so there is no risk of burning. In conclusion, lighting is an integral part of our lives and society. It provides visibility and has several psychological and physiological benefits. With advances in lighting technology, energy-saving solutions are becoming increasingly popular, making it easier for people to reduce their energy consumption.
