I am also a fan of smaller lights in general, especially the Infinity and Peak. Currently, a Fenix LD 02 graces my key ring, replacing an LD 01, also a very fine light.

Certainly one of the attributes of a "perfect" flashlight is availability - right at hand when you need a light and dependability - you will have light when you need it, right away. Carry a headband and you have a serviceable headlamp...(Don't carry it in your mouth - that is a very bad idea!) You can also easily pack replacement batteries if using the small AA, AAA, or 123 sizes.


Good point about corrosion resistant titanium. My solution is to use essentially non-leaking rechargeable NiMH batteries. No equipment that I respect will ever have alkaline batts.
