Lighting is a critical component of every home, office, and public space. Whether it's from the sun, artificial light, or both, the right kind of lighting can bring life and vibrancy to a room without overcrowding it. Natural light is one of the easiest and most energy efficient forms of lighting, and when used in combination with artificial light, both areas of a room can be lit evenly and efficiently. Sunlight naturally provides an airy, free-flowing atmosphere in addition to providing some useful warmth. Decorative window features such as blinds, shades, or louvres ensure the amount of light can be precisely controlled, while a skylight further capitalizes upon and absorbs the natural daylight available. On the other hand, artificial light is useful for settings that reject or lack natural illumination. Indoor lighting fixtures such as ceiling canopies, in-wall sconces, and track lighting can be adjusted to provide task, accent, or ambient lighting depending on the situation. The days of bulky chandeliers and brightly coloured bulbs are long gone. LEDs have revolutionised the lighting industry due to their energy efficiency and the possibility of dynamic colour and lighting regimes. Dozens of different combinations of natural and artificial light can be used to create perfect lighting schemes for any area or ambience. By continually manipulating the light levels, different lighting can be used to create a variety of effects that mark special days such as holidays or festivals. In short, lighting is an incredibly powerful tool in an interior designers toolbox that can be used to create unforgettable spaces and experiences. By combining various forms of lighting, the interior designer can fill a room with life and energy that will inspire and captivate those who inhabit it.
