The LED Lenser P5.2 is small, lightweight, and saves energy, making it one of the best flashlights you can find to carry with you. Not even 80 grams and running on just one AA battery, this amazingly bright flashlight produces a powerful 140 lumens! Even better, you can quickly focus those lumens for a far out power spot, or close up reading beam with just one hand. It’s like a little spotlight for your pocket. The lamp’s focusing system is as convincing as the one hand operation mechanism.
