light terminology thread?

Can someone point me to a thread that explains the terminology? Particularly, is there a way to discern from the model number of a flashlight what power source it uses? Do SureFire's "6P" and Fenix's "TK11" mean something standardized or is it just proprietary jibberish?

Thanks

Not many manufacturers depict the power source on the names of their products.

Personally, as far as some of Surefire's numberings go, such as 3C, 6P, 9N, the number means the voltage and, in turn, the amount of batteries that the flashlight operates on. As each CR123A (which Surefire pretty much invented) delivers 3 volts, 3C uses a single CR123A, 6P using two and 9N using three.

EagleTac is one of the few manufacturers that does it for some of its lights. E.g. - If you see A or A2 at the end of their model name, that means that the light will run on one or two standard AA formats, respectively. Same thing with a and a2, except it means AAA format. If you see C or C2 at the end, that means that they feed on one or two lithium CR123A formats, also respectively.

I don't think much of the examples. It would have been better to use "3P, 6P and 9P".


There have been several threads before attempting to explain SureFire's nomenclature. No need to start another one here if it's SureFire info you're after...
