VitalTac Flashlight Reviews Consumer Reports At its heart, the VitalTac Flashlight uses a semi-conductor diode that converts electricity into light with incredible efficiency, producing very little wasted heat compared to old-fashioned incandescent bulbs. When you click the tail-cap button of the VitalTac Flashlight, you complete a circuit that draws power from the 18650 lithium-ion battery, sending it through a driver circuit that regulates the voltage to ensure the LED remains at a consistent brightness level. The VitalTac Flashlight utilizes a half-press or 'tap' mechanism on the same power button to cycle through its internal logic, switching between the five pre-programmed lighting modes by briefly interrupting the current.
VitalTac Flashlight Reviews Consumer Reports For example, the High setting of the VitalTac Flashlight is perfect for illuminating a vast backyard or searching for a lost item in a dark attic, providing a wall of light that standard smartphone flashes simply cannot match. Conversely, the Low setting is ideal for reading a map or performing tasks that require more subtle illumination without draining the battery life of the VitalTac Flashlight too quickly. Furthermore, the SOS mode is an invaluable survival feature, allowing the VitalTac Flashlight to emit the international distress signal in the event of an emergency, such as being stranded on a remote trail or involved in a vehicle breakdown in a cell-service dead zone. For those who prioritize emergency preparedness, the dual-fuel capability of the VitalTac Flashlight is a major benefit, as it can run on both a rechargeable 18650 lithium-ion battery for daily use or standard AAA batteries when a power source for recharging is unavailable.
