Lighting produces visible light from electricity, flood light, laser, and other forms of energy. One job of lighting is to enable people to see their surroundings better. Lighting is typically thought of as a practical necessity, but it can also be used for aesthetic and functional purposes, such as lighting a stage or accentuating a room. Different types of lighting have different effects. For instance, warm and cool colors can alter the feeling of a room. Incandescent light bulbs produce a warmer glow, while fluorescent lights produce a cooler one. Also, different kinds of light can direct the eye in different directions. Spotlights can create a more focused atmosphere, while track lighting highlights various parts of a room. Proper lighting can also reduce energy usage. LED bulbs, for example, are up to 70 percent more energy efficient than incandescent bulbs and have a longer life. While they are more expensive upfront, they save money in the long run as they require less electricity to operate. Lighting is an integral part of any room or home. With the right lighting, a room can be transformed into a space that is more energizing, calming, or inviting. With so many options available, finding the right lighting for any space is easier than ever.
