Answer :
An energy efficiency improvement is replacing incandescent bulbs with LEDs.
Compared to LEDs, incandescent bulbs are less expensive. Despite LED's rising popularity over time, they are also more widely accessible. But LED is praised for having a long lifespan, being energy-efficient, and requiring less upkeep. Up to 50,000 to 100,000 operating hours, or around five to ten years, can be obtained from an LED light. As it wastes less energy by creating little heat, it is more energy-efficient than an incandescent. In addition, LED emits light in a specific direction rather than in a 360-degree circle as incandescent does; this conserves energy since it concentrates on a certain angle rather than requiring more energy for the entire 360 degrees. Despite being more expensive initially, LED also outperforms other lighting types in terms of maintenance expenses.
