Lighting is an essential part of any architectural project, and its importance should not be underestimated.Lighting can bring a space to life, as well as creating a particular atmosphere and mood. In addition to making spaces appear and feel more inviting, lighting can be used to draw attention to specific features of a room or to set a specific tone or mood. An improper use of lighting, however, can create a sense of disorientation or discomfort. Many modern lighting technologies offer fixtures, lamps, and LED bulbs that save energy and money while providing quality lighting. For example, LED lights have long life and can be used in many ways including on-off switches, dimmers, and motion sensors. Architects and interior designers can use lighting to craft everything from subtle nuances of light to striking effects. Recessed lighting, for example, creates a soft, pleasant ambience, while track lighting offers greater flexibility, allowing for more dramatic lighting accents. No matter how many new and innovative lighting solutions are developed, nothing compares to the beauty of natural light. Big windows, for example, are capable of bringing a unique quality of light into a space, completely transforming it. In short, lighting is a key factor in achieving successful architecture and interior design. When used wisely, it can make a space look inviting and unique.
