Both bright and compact, the Q4 flashlight is shorter than the penlight at just under 5" but has a larger-diameter body.
Offering a brightness range of 40 to 400 lumens, it can illuminate objects up to 200m (over 650') away. A three-position switch adjusts the beam from full intensity to a low setting or off.
From the off position, you can use the dimmer to adjust the intensity for the low setting; the circuitry saves it for the next time you turn the light on.
You can slide the telescoping lens housing with your thumb to focus the beam from a narrow 10° spotlight to a broad 70° floodlight.
At the lowest setting, the Q4 runs for up to 80 hours on three AAA batteries (included) and comes with a lanyard and a belt case.
