Turned to maximum brightness, the red light is bright enough to let you locate missing items in the grass and take down your telescope after an observing session. Medium brightness levels illuminate star charts without affecting your dark-adapted vision. Turned nearly all the way down, the light is just bright enough to let you read your watch, the focal length on an eyepiece, or the Wratten number on an eyepiece color filter.

The light is powered by a single 9-Volt transistor radio battery (supplied) that will last for dozens of hours (the exact length of time depending on the brightness level used). When replacing the battery, an alkaline or lithium battery will give the longest life. A 20" long cord lanyard is supplied that lets you hang the light close at hand around your neck when it’s not in use.
