Illumination is xtra-smooth due to a special lens over the single SUPER L.E.D., which is as bright as 3 regular L.E.D.'s, and will last up to 100,000 hours so there's no need to ever replace the bulb. It runs on 3 AAA batteries lasting up to 30 continuious hours. With an xtra-long clip this light with grip onto almost anything.
