im looking for a flashlight that i could use for edc and could work for emergencies. i dont need something thats going the throw very far and i dont need super bright im thinking 300 lumens max. id prefer long runtime over high lumens mainly because where i live budget wise im thinking 40-50 range. now i have some questions about batteries as im just starting would using aa and 14500 that can be recharged better to go or using the cr123 that ive read about on here a better way to go?
Hmmmm, AA vs CR123...
For edc, CR123 is expensive, but expensive is a relative term, depending on what you earn and what you want.
However, since you mentioned a moderate price for a light, I'm going to assume that you aren't a high-roller. In that case, I'd suggest that you go with Panasonic's
AA Eneloop NiMh cells. They give good performance, and since
they are rechargeable, over time they will save you a lot of money over primary cells. In a pinch where you can't get your batteries recharged,
you can always find AA alkaleaks to drop in temporarily.
For long-term storage of your light, or increased cold weather performance, you can drop in Energizer AA Ultimate lithium primary cells (however, they are more expensive than alkaleaks, but last much longer).
If you went with a rechargeable in the CR123 size, and ever needed primaries in an emergency, 1. it is going to be difficult to find them, and 2. when you do find them, you will likely pay dearly for them, 3. therefore you would have to buy primaries ahead of time to have on hand "just in case", 4. and you would likely want to rotate them in order to keep your reserve fresh. 5. This means that you would be consuming expensive primaries, which is what you want to avoid doing.
So I suggest that since the light will be edc, and therefore likely/possibly used daily, that you go with a AA light, and for extended runtime, two cell size.
