Lighting has always played an important role in the lives of human beings, bringing daylight and the ability to increase productivity, both inside and outside buildings. Early lighting depended on burning torches, oil lamps and candles to create a source of light. Today, advances in engineering have allowed us to create advanced lighting that uses a range of technologies from LED and CFL lights to solar power. LED lighting is a great example of how advances in technology have revolutionised lighting. They are five times more energy efficient and can last up to 50,000 hours - roughly 5 years. LEDs also produce more then twice the light output. Lighting also plays an important part in interior design. Lights and lamps provide an opportunity to add subtle touches, or highlight particular areas of your home or work environment. They also give the chance to create a mood or change the atmosphere. Finally, lighting is also important for our safety on the roads and pavements. Street lamps help to light up dark corners at night, giving pedestrians and drivers more confidence to get around safely. In a nutshell, lighting plays an essential role in our everyday lives, from providing a source of brightness and cheer to a critical safety tool. Advances in technology are continuing to revolutionise the lighting industry, making lighting more efficient and cost effective.
