The BatteryGuard™ technology on a Coleman® 350M LED Flashlight stops battery drain, so you'll have Power When You Need It™. On a normal flashlight, there is typically some residual drain as long as the batteries are connected to the circuit, even when the light is off. By turning off a BatteryGuard™ flashlight, the batteries are completely disengaged so the flashlight retains it's brightness twice as long and the batteries last 25% longer. The comfort-grip design helps minimize the chances of dropping your light, and if you do, the strong, lightweight aluminum construction and rubber-edged bezel is water and impact resistant to falls of up to two meters. That's twice the impact resistance of most other lights. No matter the situation, , a flashlight with BatteryGuard™ technology is ready, even when you aren't.
