The black Olight Baton 3 Pro Rechargeable Flashlight delivers up to 1500 lumens, a 30 percent increase from its predecessor model, the S2R Baton II. A proximity sensor automatically detects obstructions and reduces the output for safe operation. The concave side switch is comfortable and easy to operate. The customized 18650 3200mAh lithium-ion battery recharges in 3.5 hours with the magnetic USB cable and powers the light on its lowest setting for up to 120 days. Its magnetic base allows you to hang the light from the included, adhesive-backed L-shaped wall stand, and a generous-sized clip offers a secure carry on your belt or a pack strap. A knurling pattern upgraded from previous Batons feels good in your hand and looks sharp.
