Lighting, also called illumination, is the deliberate use of light to achieve a practical or aesthetic effect. Lighting includes the use of both natural and artificial light sources like lamps and light fixtures, and considerable effort is made to give aesthetic appeal to lighting design. The technical and aesthetic components of lighting are often intertwined, since good aesthetic lighting design usually requires good technical lighting knowledge. Lighting strategies have evolved over time from torches and candles, to oil lamps, gas lighting, and electric lighting. In recent times, energy-efficient lighting technologies such as LEDs and CFLs are increasingly popular as energy conservation efforts become more prominent. Because lighting can range from a scene-setting tool to a safety feature, its important to use it judiciously. One of the most important things to consider when designing a lighting system is the purpose of the project. For example, a homes main living area may require different lighting than a hallway or bedroom. It is also important to consider how much energy the lights will use, as well as how they will be controlled. Accent lighting can be used to draw attention to architectural features or art, while task lighting is used to increase visibility and provide illumination to specific areas where it is needed. Wall washing can be used to enhance the mood or feeling in a specific space, while grazing can provide added texture and depth. Because lighting is such an important part of any space, it is essential to select the right light fixtures for your home or office. LED lighting is a great choice because it is highly energy-efficient and long-lasting. CFL bulbs are also energy-efficient, but not as long-lasting. Look for good color rendering, high efficacy, and good color temperature. No matter the type of lighting chosen, you should get regular maintenance to ensure that it is working properly and efficiently. Regular inspections and cleaning will ensure that your lighting system is providing the best possible lighting and is contributing to an energy efficient and comfortable environment.
