Here's the completed list...
0) What Region/Country/State will the light be purchased in?
____I will be mail-ordering or buying online, so this doesn't matter.
____I am in North America. More precisely I am in Washington DC area.
1) Price Range: An easy question, but you may change your mind after answering the rest!
____I have no limit!
2) Format:
____I want a flashlight.
3) Length:
____2-4 inches. (Pocket carry)
4) Width:
____I prefer a long narrow light.
5) What batteries do you want to use? Alkaline batteries are easier to find and less expensive but don't pack as much stored energy and are don't work well in cold temperatures. Lithium batteries have long shelf life (10+ years, great for stored emergency lights) and are not as affected by cold but must be kept dry and are more expensive. Rechargeable start expensive, but if used frequently pay off quickly.
____I want common Alkaline batteries. (AA, AAA, C, D)
____I want lithium batteries. (coin cells, CR123, AAA, AA...)
____I want a rechargeable system. (an investment, but best for everyday use) [Yes... but recommend against rechargeables for waterproof dive lights -- gasses can't escape]
6) How much light do you want? Sometimes you can have too much light (trying to read up close up with a 100 lumen light is impossible).
____I want to walk unpaved trails. (40 lumens)
____I want to do Caving or Search & Rescue operations. (60+ lumens)
____I want to light an entire campground or dazzle an intruder. (100+ lumens)

8) Runtime: Not over-inflated manufacturer runtime claims (like some LED lights). but usable brightness measured from first activation to 50% with new batteries.
____60-240 min. (1-2 hours)
9) Durability: Generally the old phrase "you get what you pay for" is very accurate for flashlights.
