The Torch, at 4100 lumens, may be the world's brightest handheld flashlight. It also lights fires.
While the "without" / "with" examples best demonstrate the light's power as a source of illumination, its ability to quickly light stuff on fire might be thescariest most impressive way of showing off what it can do.
Battery life: 5 minutes.
There is also a neat use of the flashlight, a low light camcorder, and a 950nm IR filter here. [Wicked Lasers Previously 1, 2]

Ha, there are alot of "preparedness" enthusiasts. I know at least one guy who carries several flashlights, lethermen, first aid kits, knives, compasses and signaling devices at all times. They do stuff like buy expensive flashlights and modify them to be as bright as humanly possible to enable them to signal passing planes if they are ever stuck on a raft in the middle of the ocean.

Some of us just really like flashlight. It's like an addiction. I honestly couldn't explain it beyond, "Oh, it's dark, and in my pocket, I have a solution to that."
Some people do take it to a bit of an extreme though.

Yeah, I seem to have a weird thing for flashlights and knives. I don't collect them, but I do have 2 or 3 really good flashlights and 2 really good knives---but I'm always looking for better replacements. I've wondered if it has to do with some primitive, subconscious fascination with fire and cutting-tools), or if there's a simpler explanation. It took me twenty years to realize my desire to one day own a cattle-dog (blue heeler) was based on seeing Mad Max as a child.

By "handheld flashlight" I guess they mean battery-powered? When I was a lad we used to keep a 12V Q-Beam marine rescue searchlight in the car and use it to censor the drive-in movies — from the highway! 4100 lumens is about 50,000 candlepower; the Q-Beam was something like 500,000.

4100 lumens is about 50,000 candlepowerIs it that straightforward of a conversion? Because I got this puppy at home, and it's a helluva lot brighter than 50,000 (or 500,000) candlepower, and battery powered.

Is NicWolff correct on the 4100lumen = 50,00 candles?
Because downstairs I've got a hand held battery powered torch that claims to be 2 million candles. Fecking thing looks like it has a car headlight bulb in it and a battery pack the size of two motorbike batteries...
I'm guessing that by "torch" they mean "Maglight style handheld light"

Lumens are a measurement of total light output, and is mainly a function of how much power a light source consumes and with what efficiency it converts that power to photons.
Candlepower is a measurement of the intensity of light radiation in a given spot, and is mainly a function of how well a beam of light is focused or concentrated.
Lumens and candlepower aren't strongly connected and aren't convertible. Lamps designed to light large areas (like streetlights) produce lots of lumens, but not much candlepower. Flashlights and spotlights that are designed to throw a beam a long distance usually have relatively modest lumens but high candlepower.

Never buy anything from wicked lasers. Everything they sell is overpriced and underspec'd. They sell lasers for $2000 when you could get the exact same thing, built with better quality, off ebay for $100. Their Arctic 1W blue was probably their best deal on anything they've ever made, but the batteries are known to explode, the aluminum is so cheap that if you misthread the cap even once it strips the threading... They're just overall cheap shitty chinese goods, but somehow they've got this reputation as the best.
This is NOT the most powerful flashlight in the world, there are many handheld HID lamps available. I've seen people on candlepowerforums and laserpointerforums and photolexicon build their own from scratch for $20. You just need a halogen bulb a reflector and a battery.
Never, ever, even consider buying anything from wicked lasers.

paisley henosis : No offense but that really doesn't explain anything.
Fair enough. For me it started when I transitioned from using a big maglight type flashlight to one of those little Surefire ones that the cops were making popular. My buddy saw it and got one a little better, and the brinkmanship began. At first we were obsessed with brightness, but at some point it became useless because the lights were so bright that you couldn't use them to, say, find something on the floor of your car while driving because you'd blind yourself.
After that it became about size, the smaller the better. You wanted a light you could carry in your pocket and not notice, But at that time, the realities of what batteries were available, and what bulb types were being employed meant that there were limits on how small and powerful a light could be.
Then LED lights came on the scene, and it changed everything. It was all about the run time; a bright flashlight was cool, but a flashlight that produced usable light and could be left running for weeks? Awesome.
For people who like this sort of thing, the last couple of years have been really great. LED lights have allowed for amazingly small, stupidly bright flashlights that run on common AA batteries. Now attention is being focused on a light that can serve multiple needs, like this. Bright, but dimable. Regular batteries with a reasonable good run-time, but a secondary red LED that will let the light run constantly for unbelievably long times.
Really, the short answer is that like any hobby or fascination, there are people who really enjoy playing with all the permutations and exploring all the possibilities to eke out the best possible performance along any axis of the interest. Flashlights are no different, and this is an example of one of those extremes.
But for nearly everyone who develops the interest, it nearly always comes from the simple, primitive joy of being in the dark, and knowing that you have the power to change that.

There is quite a large community of flashlight enthusiasts on the Internet. I don't get it either.
I didn't get it either, but I've glanced at CPF from time to time -- mostly with the idea of buying a cheapo laser from DealExtreme.
Then, at some point, about three months ago, I just got a yen to buy a decent flashlight. (ie, something that costs £50 rather than £5). Not sure why I got the urge -- I've never used one for anything more than changing a fuse when it pops -- happens maybe once every three or four years.
But it was something about the aesthetics, and something about being able to buy some high quality engineering for not very much money.
I agonized for ages, but ended up buying a 4Sevens Quark123 Tactical -- mostly because they were on sale at the time, and CPF members got an additional 8% discount.
Here's the weird thing. No sooner had it arrived than I immediately wanted another one. The one I'd bought was a lovely thing -- tiny, but threw out a beam like the police helicopter. But it uses CR123 batteries, which are expensive, and hard to find. You can use rechargables, but they're prone to exploding. Obviously, I needed another one -- something that'd run on a single AA battery. Or maybe something that ran on a couple of AA batteries. Or what about that 4Sevens Quark Photon, that runs on 2 AAA batteries and looks like a penlight, but also throws out a huge amount of light for the money. They look sweet.
Then there's the whole seduction of Surefire flashlights. While a China built thing might cost you £50-75, the US built Surefires can easily cost double that. But they do look so robust and reliable.
And before you know it, you've become one of those light nerds who hang out at CPF. But there's definitely something seductive about the aesthetics of flashlights, and even the high end ones aren't *that* expensive.
Well, until you start getting into the custom build jobs...

Lumens are a measurement of total light output, and is mainly a function of how much power a light source consumes and with what efficiency it converts that power to photons.
Candlepower is a measurement of the intensity of light radiation in a given spot, and is mainly a function of how well a beam of light is focused or concentrated.
Lumens and candlepower aren't strongly connected and aren't convertible. Lamps designed to light large areas (like streetlights) produce lots of lumens, but not much candlepower. Flashlights and spotlights that are designed to throw a beam a long distance usually have relatively modest lumens but high candlepower.
Candle power is defined as (roughly) how well you can see a candle. So if a flashlight across the room is twice as bright as as the candle, it has 2 candle power. (In theory, I believe this means you can see it from twice as far away.)
If you have a source that puts out 100 lumens, you can focus the light with a mirror and still have 100 lumens of light coming out of the thing, but because you are pointing it into a narrower angle you are going to get twice the candlepower. So a laser has a shitload of candlepower, but almost no lumens.
Think of the difference between looking at a movie screen and looking into the projector lens.

Well... I'll be darned. A community dedicated to flashlights... why not, right? I really do love my little headlamp... it's remarkable how far these things have come.

rou_xenophobe: I didn't know what she meant either, but I suspected something so I headed over to google. I was trying to figure out how to search for what I wanted, when google instant told me as I paused to think after "I accidentally".

Keep this beside your bed instead of a gun. Blind anyone who breaks into your house.
IT'S LIKE A TASER FOR YOUR FACE!
blue_beetle, you may have hit on the ultimate weapons law loophole. If the packaging were remade "unthreatening" (thin aluminum/heat-resistant plastic), this thing would pass through TSA with only a few questions.
Blind an attacker to render them helpless, in a way that probably can't be tried as "aggravated" (while using a weapon). Stop an intruder two rooms away down a hallway, with no worries about police permits.

Tell me that for the money, these high-dollar flashlights go "Bwowwwwwmp" when you power them on.

I knew what she meant and was trying to set her up so that she could come back and say "The battery." Like in this, which I find inexplicably hilarious.

these high-dollar flashlights go "Bwowwwwwmp"No, but they don't turn off instantly, instead fade out. That's kinda cool.

I still just want a dual mode (LED/Halogen) headlamp with an on-off switch and a mode switch. Not a single toggle through all modes.
Also, it has to be smaller than the Pelican headlamp I found that meets this requirement, but is the size of an actual pelican.

You know when someone is driving behind you at night with their high beams on and don't realize that, given the height disparity between their hulking tactical vehicle and my squat British-inspired 2-seater that they're effectively illuminating the entire goddamned cabin?
Well, that's why these flashlights were invented.
