Energy-efficient lighting refers to lighting solutions that use less electricity to produce the same amount of light compared to traditional options. Common types include LED (Light Emitting Diodes) and CFL (Compact Fluorescent Lamps), which consume significantly less energy and have longer lifespans than standard incandescent bulbs. These lighting options not only reduce energy consumption but also lower electricity bills and decrease greenhouse gas emissions. By switching to energy-efficient lighting, households and businesses can contribute to environmental sustainability while enjoying improved lighting quality and durability.
