Thanks for the complimets brightnorm!
I'm really wary of calling what I have been doing with flashlights as "tests" because I'm not technically trained and experienced to this kind of stuffs.
These, experiments as I call them, are all done for fun and in a small way make a contribution to CPF and flashaholics gain more information, informations not provided by manufacturers like comparison beam photos of different brands of flashlights.
Yes, I also wish there is a lithium AAA battery around. I haven't tried leaving my Arc-AAA or LE's outside to freeze.
I'm a flashaholic who believes that until flashlight manufacturers come up with a common or standard way of rating flashlight lightbeams... beam photo is still the better way of knowing how good one brand's lightbeam from the other.
Unlike 'time' where one can go to
http://nist.time.gov/ or tune in to tv and radio stations to get the standard time for free, is there a place nearby where one can go to adjust his DMM to measure the standard "1 volt" or "10mA"?
Pictures may not be perfect but still it shows which beam is brighter and nicer. Btw, Photopoint is gone and I'm uploding my beam photos to a new photo host.
Craig's ProMetric equipment is really a very nice machine and shows beam quality from brightness to nice clean or rough beam. I hope Craig finds the time to use that machine to all of his flashlight. I'm even thinking of sending my flashlights to Craig so he could test them with ProMetric and have a common way of looking at lightbeams.
I think that ProMetric machine is better and more informative than the other expensive machines, "ball" as they are called, manufacturers are using.
I've been telling myself for sometime to create a website. It will contain only beam photos, runtime, close-up to show clean or rough beam, and photos to show beam throw. I leave the technical stuffs to our good reviewers Craig, Brock, Chris M., and Quickbeam.
