Product Description

The water-resistant 5" long Starlite variable brightness flashlight uses two red LEDs (Light Emitting Diodes) to help you read star charts and operate your telescope without affecting your dark-adapted vision. It has a combination continuously variable rotary brightness control knob and on-off switch. The center detent position turns the light off. Rotating the control knob in either direction turns on the light and controls its brightness.

Turned to maximum brightness, the light is bright enough to locate missing items in the grass and take down your telescope after an observing session. Maximum brightness will affect your dark-adapted vision if observed directly, so use this setting sparingly when you're observing. The Starlite is designed to turn on at its lowest level so you can't accidentally affect your dark-adapted vision by having too bright a level when switching on. Medium brightness levels illuminate a star chart 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 (with 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. An 18" long braided cord lanyard is supplied that lets you hang the light close at hand around your neck when it's not in use. The water-resistant body won't be affected by putting the light down in dew-soaked grass, snow, or a puddle in the darkness.

I use this light all the time. I like its variable brightness and comes with a neck lanyard so I don’t lose it in the dark. (Posted on 7/22/2019)
Review by:
I bought the original version of this flashlight 20 years ago. It's variability on brightness is useful for keeping dark adaptation. The original had a problem in that they put an adhesive strip in the case which made it impossible to remove the electronics and replace the nine volt battery. I originally thought the battery had leaked and swelled but that was not the case. I drilled a hole in the bottom of the case and was able to push the electronics and battery out the case and was surprised to find the adhesive. Nonetheless it is a good product and would think that Rigel would have found this error at the time. (Posted on 1/8/2019)
