Lighting has been an integral and functional part of people's lives for centuries. Since ancient times, it has been the source of illumination of our spaces. With the advent of electricity, it has been applied in a range of new ways. Lighting technology has evolved from oil lamps and candles to the most modern LED, LPS and fluorescent varieties. It is estimated that lighting accounts for about 20% of global energy consumption. With the heightened concerns about global warming, the need to find energy efficient solutions has become an imperative. LED and LPS lighting are two of the most popular types of lighting due to their energy efficiency and low maintenance costs. LED lighting is very energy efficient and long-lasting, making it an ideal choice for residential, commercial and industrial lighting applications. Likewise, LPS lighting has become increasingly popular due to its bright light, low energy consumption and low maintenance costs. In addition to being energy efficient, lighting also has the power to set the tone of a space. Through its various hues, lighting can be used to create ambience and mood - whether it be bright and cheerful, or calming and peaceful. By strategically placing lighting fixtures in a room, one is able to control the light levels and add a sense of drama and depth. Lighting is an indispensable part of our lives, in which its practical applications are essential to save energy and to create emotionally charged atmospheres. It is no surprise that lighting technology continues to evolve and improve over time.
