Lighting is a key element in all interior and exterior design. It affects the way an environment looks, feels and functions. Different types of lighting have been used throughout history. Natural light is still widely used and appreciated. Candlelight and kerosene lamps were used before the invention of electricity. Indoor gas lamps, powered by natural gas, appeared in the 1800s. With the arrival of electricity, a variety of light sources became available. Today, electricity powers almost all lighting needs. With a variety of light sources to choose from, such as incandescent bulbs and LED bulbs, it is easy to create a lighting solution to suit any space. Natural sunlight can be utilized to create beautiful rooms with plenty of natural lighting. When creating a lighting plan, consider the type of light source, design style, and colour of the space. Add layers of light by using multiple sources, such as pendant lights, recessed lighting, floor lamps, and wall lighting. These layers create depth and indirect lighting. Lighting provides a way to add atmosphere to a space. From activity lighting that brightens work surfaces to accent lighting that sets a mood, lighting is a powerful tool to add drama and flair when used correctly. It is important to consider the various lighting solutions available when planning a space. Good lighting can make all the difference in creating a successful outcome.
