Celestron Variable Brightness Dual Red LED Astronomer's Flashlight 93588

This Celestron variable brightness red LED flashlight uses two red LEDs (Light Emitting Diodes) to help you read star charts and operate your scope without affecting your dark-adapted vision. The Celestron VLED combines an on-off switch with a rotary thumbwheel variable brightness control that lets you easily adjust the brightness over a wide range with a simple flick of your thumb.

Turned to maximum brightness, the 4.25" long 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 alkaline transistor radio battery (supplied) that will last for up to 600 hours (the exact length of time depending on the temperature and brightness level). When replacing the battery, an alkaline or lithium battery will give the longest life. A 20" long looped cord lanyard is supplied that lets you hang the light close at hand around your neck when it's not in use. The body is not water-resistant, so be careful you don't put the light down in dew-soaked grass, snow, or a puddle in the darkness when it's not in use.
