I don't really understand the concern over the use of three N cells.<HR></BLOCKQUOTE>
I agree completely- there is nothing wrong with an N cell - quite the opposite when you consider it replaces 15+ sets of button cell (357 equiv) batteries!
I've used N cells for 20 years - back in the HP41C calculator - never had a problem finding them - drugstores, supermarkets, photo stores, or if no reasonable alternatives exist, rat shack.
The N cell has the almost the endurance of an AA alkaline which no button battery can come close to, in a more compact package that permits a stack of 3 Ns in less space than 2 AAs. The Streamlight makes good use of this feature to produce a true "keychain" light that you can use for 1-2 hours if needed and still have a half day's runtime remaining.
That sort of runtime is unheard of in button cell flashlights. Most of them are very dead in 60 minutes.
Another often overlooked streamlight LED advantage is that it operates the same as the surefires - momentary button and twist the tailcap for lock-on use.
Best part is that on a keychain, you always have a bright light and good batteries with you, even if you left your 2x123 flashlight in the car/at home, etc.
My baton light has been riding on the keychain for over 6 months now - no failures and just 1 set of batteries - even with daily use and long "on" times (30 min or more). Its cost to operate (even with the N cells) is soo low that you end up using it like a rechargable - locked on until you are done with it.
