Lighting is important in a wide variety of situations—from business and industrial applications to residential and commercial settings. It provides visibility, safety, and aesthetics to any environment, as well as contributing to energy savings and positive environmental impacts. Lighting is a critical element in all interior and exterior design schemes. Good lighting can add drama, accentuate a feature, or simply create ambiance. Warm, yellow tones are ideal for a cozy, inviting atmosphere, while in retail applications cool, white lighting makes a space feel more open. Lighting specialists are knowledgeable about the different solutions available to meet diverse needs from across various industries. The advancement of LED lighting has made innovative solutions possible. LED bulbs last up to 25 times longer than traditional incandescent lights and are vastly more energy efficient. Sun-tracking LEDs can even be programmed to use natural daylight in certain situations. LED lighting is also extremely customizable, allowing users to craft designs and color schemes that are perfectly suited to their space. As performance and economic benefits of lighting are being realized, the adoption of smart lighting technologies is growing rapidly. With controls, sensors, and dimmers, lighting can be adjusted to meet whatever the users needs may be. From motion sensors to intelligent timers, smart technology allows users to harness the power of lighting to customize their environment and energy consumption. Lighting can be a powerful, useful tool in a wide variety of settings. From state-of-the-art lighting systems that reduce energy consumption to carefully programmed fittings that set the mood for an entire room, it is becoming harder and harder to ignore the importance of lighting in modern life.
