For those who need a bright but exceptionally compact flashlight, the Q2 flashlight is shorter than the penlight at just over 4 1/2" but has a larger-diameter body.
A three-position toggle switches from full intensity at 200 lumens to 40 lumens or off. With your thumb you can adjust the telescoping lens housing to focus the beam from a narrow 10° spotlight to a broad 70° floodlight.
It comes with a lanyard and a case that attaches to a belt. Illuminates areas up to 150m (500') away.
Uses one AA battery (included) and runs for up to 5 hours.
