Energy efficient lighting refers to lighting systems designed to use less electricity while providing the same or better brightness compared to traditional lighting. This includes technologies such as LED (light-emitting diode), CFL (compact fluorescent lamp), and smart lighting systems.
The concept exists to reduce unnecessary energy consumption and improve overall efficiency in homes, offices, and public spaces. Traditional lighting methods like incandescent bulbs convert much of their energy into heat rather than light. Energy efficient alternatives focus on maximizing light output while minimizing energy waste.
These systems have evolved due to advancements in electrical engineering and environmental awareness. Governments, industries, and households now prioritize lighting that supports sustainability without compromising functionality.
