The expander lens supports fine focus adjustment. After focusing, the beam can penetrate courier boxes at 15 meters. It delivers an extra-large true circular spot. The light spot is processed by three-stage compression to achieve excellent quality of both light spot and beam column. Suitable for astronomical observation, long-distance indication, rescue and other professional scenarios.\u003c\/p\u003e\n\u003cp\u003eMaterial: Aluminum Alloy + Carbon Fiber Battery: 3.7V 26650 high power lithium battery, backward compatible with 21700 \/ 18650 lithium batteries Length: 24cm Battery Life: Max brightness continuous runtime around 2 hours on single battery.
