Development started with the proven foundation of the stable asymmetrical single arm bracket, integrated essential modes to please a wide variety of discerning users, and tied it all together with an easy to use interface. Sync allows direct access to a red LED, spot beam, and flood beam by a twist of the power dial. For those times that require max output a further rotation of the dial activates Dualbeam mode - spot and flood at the same time. Output: 90 Lumens, Burn time: 200 Hours, 3 AAA, 83g. Assorted colours.
