How long will the DME Emergency Flashlight last once activated?

Explanation:
The main idea here is how long an onboard emergency light is designed to stay on after it’s turned on. The DME Emergency Flashlight is specified to provide usable illumination for about four hours once activated. This duration ensures there’s enough light to guide passengers to exits and for crew to perform essential actions during an evacuation, even if cabin power is out. The four-hour endurance comes from the battery capacity and LED performance chosen for this system, balancing reliability with weight and cost. After roughly four hours, the light will reach its end of usable life for that activation, at which point it would need replacement or recharging as part of maintenance.
