Your favorite light format?

Single AA/14500 in a broad voltage light like the Quark.

As a sub-/low lumen fan, the small cell runs forever for me. Most of my gadgets are AA Eneloop based, so the commonality is super convenient and gives me endless back-ups. I really like being able to use ALL the different battery chemistries tailored for my needs at the time - from the ubiquitous NiMh/Alkaline/Lithium primary (L91) to the (R)CR123 equivalents, the 3v CRAA and 14500 Li-ion. Also in a real pinch (with a piece of tinfoil I EDC in a wallet), it's nice having the option of being able to run 1.5v AAAs and AAAA (from a 9V); and also wider cells like the CR123s, 18650, etc.

I was forced to answer 1xcr123 because of the EDCability Format while still having good output/runtime ratio. I do prefer AAA for keychain duty and other factors for specific purposes.

I voted 1x18650. I always loved the 1xAA lights, and still do, but it's hard to argue the capacity and output of a single 18650 in many situations. Like this weekend - I'm going backpacking Friday night - Monday. My H600w will be nice to have and I don't need any spare batteries. I could definitely get by with the H51w, but it's nice to have the extra output and more importantly, much longer runtime in a package just a little larger/heavier.

I voted AA/14500 but actually I like the CR123 format as well. Ideally, a light like the Zebralight sc80 is my favorite EDC. It can handle both formats without the need to carry any extra bits or extensions.

Had to go with the single 18650 for the same reasons that most did. Great power and run-time, is perfect size if you are keeping it in your hand. I don't mind the size for EDC, I just holster it rarely notice it that it's there. When I do notice, I usually smile :naughty:.

Like a couple other members, being able to also use CR123 batteries in a pinch is really the icing on the cake. I have helped a few people at work pick out flashlights and they are all using 18650 type lights with cr123 batteries because they like the flashlight but don't want to mess with rechargeable batteries. I have one guy that keeps buying batteries from me, which I love because it is helping me turn over my stock of cr123 batteries so I can keep my emergency supply fresh :twothumbs

I really like the 18650 format (what the majority of my lights are), but have starting to really like the small 16340/cr123 lights (which is nice for more formal/dressy clothes). Then there's the 14500s. Dangit, I guess I like all the li-ions. Anywho, I voted single 16340 because that's my favorite for the time being.
