LEDs are now used more for than just the blinking lights on a stereo receiver or calculator display. You see them everyday in automobile and over-the-road truck tail lights because they offer incredible life and are extremely bright without requiring a lot of power. Streamlight chose a super-bright Luxeon ﾮ Star brand 1 watt LED for this versatile illuminator in order to provide lots of light in a compact package. The flexible stalk allows you the point the light where it's needed and a tough, machined aluminum case is even "O" ring sealed for water resistance. A magnetic clip (included) lets you attach the light to almost any steel surface - making it ideal for use when trouble-shooting jobs. You'll get 3 hours of light at maximum brightness and 1-1/2 hours of light at declining brightness from the two "AA" batteries (included). Imported.
