Lighting is an important feature in all homes and businesses. It provides the necessary illumination for activities and safety in the home, the workplace, and in public. Lighting also has aesthetic appeal and can be used to create a certain feeling or atmosphere. Lighting has changed a lot over the years, with the introduction of energy efficient lighting options such as LED and CFLs to traditional lighting sources such as incandescent and halogen bulbs. LED lighting is gaining popularity due to its convenience, energy efficiency, long life, and controllability. LEDs use a fraction of the energy consumed by traditional incandescent bulbs, making them a much more environmentally friendly option. Additionally, LEDs last for many years longer than traditional bulbs, thus reducing overall energy consumption and cost. Lighting designers and architects consider many factors when designing lighting plans for homes and businesses, such as lighting levels and direction, colour temperature, and colour rendering. They also select lighting fixtures that enhance the room's aesthetics, provide flexible lighting options, and control glare. Lighting is a vital component of modern life and is an important design consideration for all buildings. With the introduction of energy-efficient lighting options, lighting can be used to reduce energy consumption and create a comfortable and aesthetically pleasing environment.
