INTENSE BRIGHT LIGHT output comes from the ultra-efficient LED. The LED does not fade when it gets hot, so its light output is stable even after extended run times.

FOCUSABILITY These LED Point source lights preserve one of the most outstanding features of many flashlights, the ability to focus. A focused beam that throws a bright beam a very long distance.

LONGER BATTERY LIFE results from the higher efficiency of the LED compared to the standard incandescent bulb 10 Lumens / watt. These LED maintain a brighter white light output as the batteries discharge than incandescent bulbs which turn to an amber light.

INDESTRUCTIBLE LED performance and lifetime operation. Unlike incandescent bulbs with a thin fragile filament that breaks, LEDs wear out very slowly. This is likely to be the last bulb you will ever need to buy. The rated lifetime is 50,000 hours.
