LED bulbs are known for their impressive longevity and efficiency compared to traditional incandescent and fluorescent bulbs. Under ideal conditions, LED bulbs can typically last around 15,000 hours. This extended lifespan is due to their solid-state lighting technology, which is more durable and less susceptible to burn out, unlike filaments in incandescent bulbs which can fail due to fatigue over time.

While options such as 5,000 hours and 10,000 hours may represent the lifespan of lower-quality or less efficient lighting solutions, they fall short of the expected performance of high-quality LED bulbs. Similarly, 20,000 hours, while certainly possible for some LED models, is generally considered the upper limit for many common applications rather than the average lifespan under ideal conditions. Therefore, 15,000 hours serves as a reliable benchmark for effective LED bulb longevity, making it the most accurate choice in this context.
