An LED light bulb is a type of lighting that uses light-emitting diodes to produce light. Unlike traditional bulbs, such as incandescent or fluorescent lights, LED bulbs are more energy-efficient and have a longer lifespan. They convert a higher percentage of energy into light, which helps reduce electricity costs. LED bulbs come in various shapes, sizes, and colors, making them versatile for different lighting needs. They are commonly used in homes, offices, and outdoor spaces. Additionally, LED technology is environmentally friendly, as it contains no harmful substances and reduces carbon emissions when used to replace less efficient lighting options.
