LEDtronics introduces a new design of its popular KeyLED, a take-along miniature LED flashlight. The new KeyLED is smaller, lighter and more powerful. KeyLED's 5mm white LED emits 10-foot candles (6Kmcd) of bright light that's powerful enough to light your way. KeyLED operates on four, replaceable, watch-cell type alkaline batteries (LR1120 series or equivalents). Since LEDs are 80 to 90 percent more energy efficient than incandescent lamps, KeyLED flashlights operates 20 to 30 times longer than the comparable incandescent flashlight to provide hours of continuous illumination.
