Rigel Systems Starlite Mini, 2-RED LED Flashlight
The bestselling astronomers' flashlight with 2 Red LEDs. The intensity is fully adjustable with Thumbwheel Brightness Control. Exclusive brightness regulation circuitry keeps the LEDs shining bright as batteries age, unlike other LED flashlights which start bright but quickly fade.  The Mini Starlites are only 3.5" long, 2 inches shorter than the standard Size water resistant version.  NOT water resistant (sorry there's only so much we could squeeze in), but all the other great features in a smaller, lighter case.
