We wanted to show how much light is generated by this relatively small flashlight. In order to do this, we decided to show a comparison between a regular halogen flashlight powered by two D-cell batteries and the Ledwave flashlight (X-55) powered by two CR123 lithium batteries.
On a dark night in Simi Valley, California, we mounted our camera on a tripod and aimed it at a garden backdrop about 40 feet from the lense. In both pictures, the camera's exposure was manually set to 2sec/F2.8.

Why is L.E.D technology so much brighter?
Unlike a traditional incandescent bulb, an L.E.D. is a solid state device. The creation of light takes place at a molecular level rather than through those of a filament. This gives L.E.D.s three main advantages over a standard incandescent bulb:
ENERGY EFFICIENCY A regular incandescent bulb emits light because electrical current is passed through a thin wire (called a filament) which is inside a glass vacuum bulb. A huge amount of energy is wasted in this process, and is released not through light output but by heat (which is why a standard bulb is hot when in use.) An L.E.D. does not have a filament to "heat-up" and thus there is not lost energy, making L.E.D.s approximately 3-5 times more efficient than incandescent bulbs.
LONG LIFE The light emitting portion of an L.E.D. has a 100,000 hour life span. A standard incandescent bulb will typically burn out in less than 40 hours.
MECHANICAL RELIABILITY The components of an L.E.D. are encased in a virtually indestructible high strength optical grade epoxy. There is no glass or filament to break, making L.E.D.s perfect for rugged environments and temperature extremes. In incandescent bulbs, even if the glass casing of a bulb stays intact, the filament can break from sudden shock or a soft drop, even when housed in seemingly indestructible flashlight housings.
