2500-Lumen Peak Output, 21700 Battery, 47 Days Runtime, Magnesium-Alloy Housing, IPX8 Waterproof, Shake-to-Wake Battery Indicator, Recessed Side Switch, Magnetic Base with Wall Mount. Featuring shake-to-wake technology and a more powerful battery than previous models the brass limited edition stonewash 2500-lumen rechargeable Olight Baton 3 Pro Max Flashlight fits big capability in a compact EDC package. A quick shake lights the battery status indicator LED which also makes it easier to find the recessed push button in the dark. The 21700 battery powers the light for up to 47 days depending on brightness levels used while the light's proximity sensor automatically detects obstructions and reduces output for safe operation. The magnetic base allows the light to hang from the included L-shaped wall stand and a generous-sized two-way clip provides for a secure carry in your pocket or on a pack strap. A knurling pattern upgraded from previous Batons feels good in the hand and looks sharp.
