Short and Long-Distance Illumination The LED Lenser P7 flashlight with three settings delivers up to 175 lumens and boasts a maximum beam distance of 600 feet on high for up to 13 hours of run time. The Advanced Focus System lens/reflector combination optic allows for quick switching between a non-eye-fatiguing spill beam, suitable for reading up close, to a focused, powerful spot beam, best for long-distance viewing. In addition, the Rapid Focus system transitions between settings with a simple slide of the bezel.
