LED lights are known for their energy efficiency and significantly longer lifespan compared to incandescent lighting. This is primarily due to the way LEDs (light-emitting diodes) convert electrical energy into light. Unlike incandescent bulbs, which generate light by heating a filament and can waste a large portion of energy as heat, LEDs produce light more efficiently, using a much lower amount of energy for the same lumens (brightness) output.

The lifespan of an LED bulb can range from 15,000 to 50,000 hours or more, while incandescent bulbs typically last only about 1,000 hours. This extended lifespan means that LED lights require less frequent replacement, which also contributes to lower maintenance costs over time.

Energy efficiency is another key factor, with LEDs typically using up to 80% less energy than incandescent bulbs to produce the same amount of light. This not only leads to cost savings on energy bills for consumers but also has a positive environmental impact by reducing overall energy consumption.

In contrast, the other options do not accurately reflect the characteristics of LED lighting. While LEDs can provide a range of color temperatures, they often do not inherently provide warmer light compared to incandescent bulbs, which are known for their warm, soft glow. Furthermore, LEDs generally require less maintenance
