I have an older version: the EA4W. It's downfall is it uses a single button to access all modes. It's not intuitive at all. If it were the only light I carried, there would be no problem. But, I have lights all over the place and pick up the one that's most handy when needed.

Looks like they heard the complaints and gave this model 2 buttons.

I hope that battery pack can handle that much current safely, Esp. that much heat, without going into thermal run-away........which can be interesting to watch. :geek:

You need to realize that any such high-intensity flashlight contained in such a small package would (by necessity), be used only in short bursts.

Which leads me to their lasers, which are probably of the same design and not designed for a long-term output (more than several seconds at a time - which is how the consumer laser/flashlight market works - other than that including the LEO market which needs bright flashlights for moderate lengths of time).

Looks like the pack is built up from the 'standard' lithium lego cell, the 18650. I've seen high discharge 18650's that are rated for 20 or 30 amps (yes people buy them specifically for that capability), but the ones I have for my flashlights wouldn't deliver more than 5 or so amps. Oh, and the thermal runaway, in a flashlight tube that's like a pipe bomb. :shock:

Oh certainly. But with LED lights that have proper thermal design, you could get quite a bit longer bursts and much more runtime overall, with no worries about flash-bulbing your incredibly expensive 100W bulb.

Chinese flashlights can be very hit or miss, but Fenix is one company that's made an effort to make consistent quality lights (and be able to charge a price premium accordingly).

http://www.fenix-store.com/fenix-ld60-led-flashlight/

Is a sample of a 'beer can' light. That format is pretty popular for a light with multiple LED's and multiple batteries that doesn't need a big reflector 'head' for throw. For a more generic Chinese budget light version, look up 'Skyray King' or 'SRK' there's a whole little industry that's grown up around versions of that basic format.

http://www.fenix-store.com/fenix-tk75-x ... 00-lumens/

Has a thick handle to hold the batteries, and a big reflector head for throw. There are also various generic Chinese budget lights like this, it's not really my thing but I've heard good things about one called the 'BTU Shocker' (yes really, that's the name).

These offer max output in the same type of ballpark as the 100w torch - perception of brightness is logarithmic so the perceived brightness difference will be much less than it appears on paper - with enormously better runtimes, multiple brightness levels available for different types of task and longer runtimes, etc. (And some versions of things like the SRK will actually be brighter than the incandescent.) And at most they should be drawing ~3amps from the batteries.

Workin',

Battery Junction has JetBeam PA40 LED Flashlights, with CREE XM-L LED, 468 Lumens, and use 4 x AAs, for $51.75 with free shipping.

I have one, I really like it. The flattened handle slides into a back pocket. It's probably all the flashlight you need for 95% of your flashlight uses. It's a little longer than you requested(7"), but otherwise meets your specs.

Thinking about a better quality keychain sized light(s) for my daughters. Need to start looking more actively. Would like something better than what's available in the checkout line at the typical autoparts store.

A single AAA like the Fenix E05 would be the classic keychain like but since they carry keywads in huge purses maybe step up to something like a Fenix E12.

I've not used the Fenix, but I bought this Olight a while back, and I love it. If I lost it, I'd buy another. You need to replace the cheesy little triangle with a split ring and the chain with 0.5 size s-biner.
Note to self: start reading sig lines. They're actually quite amusing. :D

No experience with the Olight, but the Fenix 12 is my edc. I really like it. 4+ months on a single battery. works every time so far and I have not been a drop free owner. Probably at about 9 months now and on battery 2.

Sounds like either is a good way to fly.

Yeah, I wrote up my initial impressions here on another thread re: the Fenix E12. I just bought another (for my wife). She likes it very much.
And may I say, from a moral point of view, I think there can be no justification for shoving snack cakes up your action.

LED Lenser

http://www.amazon.com/LED-Lenser-HP8407 ... led+lenser

It is a 40 dollar light (ignore the you save 1 billion dollars bullshit)
Used it as my service light for 6 years before the batteries exploded in it. Tough little cookie, bright as Jesus's taint on the sabbath.
