Lighting is an important part of daily life, both indoors and outdoors. It helps to create a setting, provide task lighting, accentuate architectural features, and, most importantly, provide illumination for safety and visibility. Lighting used outside usually employs bright, large-scale fixtures to light up parking lots, walkways, gardens, and other exterior spaces. Solar lighting has become a popular alternative to traditional lighting because of its efficiency. Indoor lighting performs a range of functions—setting mood, aiding task lighting, and providing a comfortable level of illumination. Incandescent and LED bulbs are the most common and versatile type of light sources for interior use. LED lighting gives off a bright but diffused light with the added benefit of being more cost-effective and energy-efficient than other bulbs. Often, a combination of lighting fixtures is needed to create the right effect in a room. Wall sconces, track lighting, pendant lights, and recessed cans are just a few of the many types of fixtures available. It is important to select the right lighting fixtures for any given space to achieve the most pleasing effect. Different types of fixtures are better suited for different functions, and it is important to have a basic understanding of lighting design so that the fixtures chosen can provide both task lighting and overall illumination. Finally, it is important to remember that lighting serves a practical purpose and should be installed and positioned correctly from the start. That way, it will serve its purpose and last for years to come.
