Lighting is one of the essential elements of modern human life. Without proper lighting, our lives would be much more hazardous and far less comfortable. Over the years, the lighting techniques and products available to us have changed and expanded drastically. We can now choose from traditional lighting sources like incandescent and fluorescent bulbs, to more modern, energy efficient varieties like LEDs. While traditional bulbs may be cheaper initially, LEDs are much more efficient and can save you money in the long run. In addition to the type of lighting used, the position and placement of lighting can also have an effect on the atmosphere and mood within a space. Utilizing layers of light, creating a warm glow, and adding task lighting to areas like a desk or kitchen counter are all effective ways to utilize lighting and add character and personality to a room. Lighting can also be utilized for safety and security purposes. Motion sensor lights are great for deterring intruders from entering a home, while brighter exterior lights can serve as a deterrent during the night. Lighting is not only a necessary part of life, but also a powerful tool able to be used to create beautiful and comfortable spaces we use on a daily basis.
