    Default Stinger Candlepower vs. Surefire Lumens ?

    Hi,
    I am new to the board ! Looking at the specs. for a Stinger vs. Surefire and I noticed that the Candlepower spec for Stingers is 15,000 ! how does that convert to a lumen reading to compare against the Surefire ?

    Thanks,
    Aero

    The short answer is that it doesn't. They measure different things.

    Lumens measure the total light output, while candlepower measures the brightest point within a beam. A high lumen bulb with no reflector or optics to focus the light into a beam will have low candlepower and a low lumen bulb with a narrow beam reflector/optics can have high candlepower.

    It would be nice if flashlight manufacturers gave an ACCURATE specification for both, but I don't think I've seen any that do.. (Maybe Mag? Don't they have both on their spec sheets now?)

    SureFire give accurate (realistic) Lumen ratings for their products. I guess you need to outline how you measure Candlepower. Lumens in an integrating sphere is scientific.

    I don't think there is a flashlight company that DOESN'T inflate the numbers...

    Unfortunately, you can't compare lumens to CP...Other than by sight...
