The BR10 GT LED bike light is now even brighter. Whether youre mounting the BR10 GT onto a bicycle, a weapon, or using it as a stand-alone flashlight, the BR10 GT is a truly versatile flashlight. The BR10 GT measures in at 4.4 and is constructed from aero-grade aluminum alloy with a military grade hard-anodized finish, making it extremely compact and durable. Also, the BR10 GT is IPX-6 waterproof and impact resistant up to one meter, so you wont have to worry when youre out on a ride and it starts to rain. Fitted with a CREE XM-L2, the BR10 GT now outputs a scorching 960 lumens, with a maximum throw up to 180 meters, which is amazing when youre on your bike at night. Cycling between output modes is done by long pressing the circular power switch, starting off in the 100 lumen Low mode and progressing to High mode. Double pressing the power switch will enter strobe mode, for those emergency situations. The BR10 GT is powered by a single rechargeable Li-Ion 18650 battery, and the best part is, its included. You can easily charge the battery using the USB charging port located on the light. Plug it in to your computer, while at home or in the car using your cigarette lighter, with a DC adapter of course. A water-resistant rubber cover ensures the BR10 GT is safe, when not charging. The back lit triangle indicator will keep you updated on the power status with green indicating 50-100%, blue indicating 10-50% and finally red indicating under 10%.
