Lighting plays a vital role in our daily lives. Whether used inside or outside our homes, it allow us to see our surroundings and make tasks easier. Technological advances have made the modern lighting industry a huge business. Indoor lighting has advanced significantly over the last few centuries. An early invention was the light bulb, which allowed people to read at night. Over the years, fluorescent and LED bulbs have become the standard, providing efficient bright light in a variety of colours. LED lights are being used more and more in residential applications as they are more energy efficient than traditional models and last longer. But natural light is still vital to the well-being of humans. Many modern homes now feature large windows, sliding glass doors, and skylights to let in natural light during the day. Outdoor lighting, also known as landscape lighting, creates a warm and inviting atmosphere in any outdoor space. It is often used for aesthetic and safety purposes, to highlight paths and outdoor features. Low-voltage LED outdoor lighting has become increasingly popular, as it is far more efficient than traditional incandescent bulbs. As lighting technology continues to develop, manufacturers are investing heavily in research to create better, more efficient and longer-lasting products. For both residential and commercial structures, lighting is an essential component that enhances beauty and promotes safety. It is an integral part of interior design and a crucial part of our everyday lives.
