    Measuring light....

    I'm still confused and I'm sure not for lack of good explanations... How are lumens and lux seen? Or, can the difference between the two be seen...? And what ever happened to candlepower...? I use an example of a garden hose size, pressure and water to visualize the difference between voltage...

    Measuring light....

    If I understand lumens and lux correctly, it's the measurement of "brightness". Is this what is referred to as density...? Is there a measurement for volume...?

    Batteries, Shelf life vs. Activated life...

    SureFire VS. StreamLight In General

    Ok, with my limited knowledge, here goes... Is this for duty use or general civilian use...? My issued duty light is a Streamlight Stinger but I also carry a Surefire C3 or a Z2 at the same time. The differences that I can see are the beam width. The Stinger has a more concentrated, or...

    Batteries, Shelf life vs. Activated life...

    I see that the shelf life of alkyline batteries is approximately 7 yrs from when shipped from the factory. But it appears that once the bats have been placed into service (activated) that they loose that life expectancy. Is this a good observation...? If so, what takes place with a bat once...

    Lithiums after 10 years?

    So, after ten years, will they still preform as new and give normal expectations of usage life or will they drain quicker...?

    [ QUOTE ] Spectre said: 123's and 123a's are the same. Your Z2 surefire is a 2 cell model and use the P60 (65lumen)incadescent bulb/Lamp Assembly. It can also use the P61 LA for high output - 120lu/20 min runtime. Your Centurion use the same bulb if it is a 2 cell model or the P90/91 if it is a...

    What kind of bulb is in my Surefire Z2 and Centurian...? It's not an incandesant bulb is it...? Are 123's and 123a's the same battery...? See... I'm already

    My Surefires run on sf123a's. Are you abbreviating or is there a diff between the 123's and 123a's...?

    Chop, I'm already seeing that I'll get along ok here... You remind me of a bud that's pretty bizzare also... A fellow in another forum pointed me in this direction. I've got probably a dozen flashlights around the house and vehicles, mostly Maglights. I know, not much by some standards but...
