How long do LED light sticks typically last if left on?

LED light sticks are designed for longevity and efficiency, with many models having a lifespan that extends considerably beyond traditional light sources. Typically, when left on continuously, LED light sticks can last around 20 hours. This makes them particularly suitable for emergency situations where reliable lighting is essential over extended periods. Their ability to maintain a bright output without significant degradation of light quality is a key factor that contributes to this duration.

Other options suggest shorter lifetimes that don't align with the capabilities of LED technology, which is known for its energy efficiency and long operational life compared to incandescent or fluorescent alternatives. Hence, the choice of 20 hours captures the expected average for many LED light stick variants designed for safety and reliability in emergency situations.
