The Olight R50 Pro Seeker has an impressive maximum of 3200 lumens from the Cree XHP70 Cool White LED and is powered by an included 26650 Li-ion battery. 

The flashlight is rechargeable by a magnetic USB cable, which comes included with the torch. Simply attach the magnetic disk to the base of the torch and plug the other end into a USB port to charge the battery. This innovative design allows for convenient, practical charging and as it does not require an external charger, is ideal for use when you are on the go.

Similar to the R50 Seeker, the Pro version has a translucent side switch and chamfered edges to achieve a premium look, feel and operation. Press the switch for on and off and hold to cycle through low, medium and high. Double click the switch to access turbo mode or triple click for strobe mode. The torch also features a lock out function; with the light off simply hold for 1 second when it will turn into low mode, then hold for a further 2 seconds to reach lock out. To unlock hold the side switch for approximately 3 seconds.
