LED lighting

Definition

LED lighting refers to the use of light-emitting diodes (LEDs) as a source of illumination, known for their energy efficiency, longevity, and low heat output. This technology significantly reduces energy consumption compared to traditional incandescent and fluorescent lighting, making it an essential component in modern energy-efficient building systems and conservation efforts.

5 Must Know Facts For Your Next Test
