At just 17 grams, the Point is virtually weightless; a press of the large, convenient button activates the light on a flexible neck to direct light wherever it is needed. The LED is recessed into a rugged aluminum head, providing directional light and eliminating the chance of blinding fellow riders while reading a map, for instance. Two included Lithium coin cell batteries will provide up to 36 hours of burn time. LED color choices include, white, blue, green, and red. 10 lumens. .6 oz.
