From camping, outdoor exploration, or even trying to navigate around your house after a power outage, flashlights come in handy. This is why you need a flashlight that won't let you down. You won't have to worry about the bulb burning out any time soon. Each flashlight bulb has an LED life of 100,000 hours or more.
