If you had to choose the number one most indespensible must have flashlight that every person should have what would you vote for?
My vote would be for the Photon Microlight, any version.
OK, Lee. I agree the "Photon Microlight" is darned handy. I bought a bunch of 'em from Laughing Rabbit distributors when they were $15 or more each and a white LED was a rarity that few had ever seen. Over the years I've bought maybe a couple of hundred fauxtons, including 40 from Dealextreme this year (Christmas handouts for my co-workers). At about 40 cents, they are great giveaways.
But I have considered this question (in the form of what light do I give my _friends_) as it has become sort of traditional for me to give lights as Christmas gifts.
Part of this is a cost concern in the "every person" vector. I carry a Fenix LD01 with an L92 lithium cell and I have several of these lights, the backups with Eneloops. My ideal carry light. It fits in my jeans watch pocket, and it will handle just about any personal lighting need. A pretty strong beam, a good runtime; all in a compact package. The LOD-CE Q4 I bought last Christmas has survived a year of heavy use, and even made it through a wash and dry cycle in a pair of jeans with no ill effect.
But I think a price near $50 is too much for "every person" and the expensive ($2.50 or so) lithium or the select type NiMH is difficult for everyman.
The "microlight" is a great little gizmo, but I have not found them to be truly reliable. Look closely. This little invention uses a T5 diode which was designed to be a through-hole mounted leaded component, soldered in a circuit board. The Photon works by squeezing two tin-plated leads on either side of a sandwich of two batteries. I continue to be amazed that it works at all. Why doesn't it short and run the battery down? (to answer my own question, I think it sometimes does). We have no switch, no regulation. The 6V 80 mAH batteries are actually overdriving the diode, and the current load will sink the voltage of the battery in minutes.
There are legions of people who claim to have carried one for years, and they work like new. In my pocket and with my usage, a few months is max, and the 2016's are hard to find retail at reasonable prices. But anyway, buying the $1 (or less) Chinese clones is very sensible, and having one on the keychain when you need to light a dark corner for a few seconds is great.
But the "must have" concept for my close friends is the $10 Fenix E01. This light uses a AAA alkaline that can be found anywhere for 50 cents or so, and the AAA will yield 1,000 mAh or so at the current load of the E01.
The E01 will last for years, and it can provide a lot more illumination for much longer duration. I agree that the Nichia LED in it isn't a very nice white, but it's a real value at the price, much moreso than the "Photon" which is essentially just some batteries, an LED, and a couple of plastic moldings.
The value and practicality of the E01 is unmatched, so I consider it the everyman light.
