How bright is 770 lumens' Figure that your average car headlight cranks out around 800, and the NiteRider MiNewt Pro 770 Enduro Headlight comes across as pretty darn impressive, especially when you consider its low weight and immense running time. The 770 compact chassis means it can fit comfortably on nearly any handlebar, thanks to the included mount. The self contained light houses a 4 cell Li ion battery, which is fully recharged via the included USB cable in only 5 hours. A host of flashing and steady modes including S. O. S. mode and a low speed walk mode mean you can dial in the 770 to nearly all riding conditions, including those of the weather, thanks to a durable, waterproof housing. And, like all NiteRider lights, a proprietary lens shape is employed in the MiNewt to distribute all 770 of its lumens across a wide, uniform beam because brightness is only half of what makes a great light a great light.
