Which LED Flashlight Do You Use?
An anonymous reader asks: "There are now a LOT of LED flashlights on the market. A quick Google turns up 59,000 hits. Some of these flashlights are pretty ballsy. The LightWave 4000 contains 10 LEDs and offers one month of continuous light output. The Photon MicroLight is bright as all getout and goes on your keychain. The EverLED will go in a MagLight or any other high quality existing flashlight. There is even an entire web forum devoted to modifying existing flashlights to use LEDs. What experiences have Slashdot readers had with LED flashlights, and what recommendations would you make to a choosey buyer?"
Imagine a beowol....ahhhh forget it.

If you really wanted a cool flashlight you'd get one of these from thinkgeek and support OSDN!

I'm blind... you insensitive clod!
Beauty is in the eye of the beerholder.
Go to Dan's Data.
I found these guys a REI.com on sale for $7 bucks a peice, I bought three of them about two years ago and am still on my first one. I put it on my keychain and use it at least once a day for finding stuff in my car at night, plugging and unplugging cables behind dark desks, and pushing it really hard into the palm of my hand so i can see my veins.
Pretty cool stuff...

Got it for my significant other after she had a bad experience with a Mag Lite and a puddle in some dark woods.
Apparently Streamlight is the brand of choice for rescue workers.

They are pretty hard to find, but if you want the ultimate battery life, look for an LED flashlight with a driver. We're talking about... like 4-10 times the battery life of a resistor run (no-driver) LED here. The EverLED is one such product, but the driver is somehow contained inside the bulb, so it can be used to replace normal incandescent bulbs (it's the same form factor as the normal drop in flashlight bulbs). Pretty cool.
My specific use is that I hike the lava fields at night here in hawaii... On moonless or cloudy nights it can be pretty dangerous because of the huge cracks (some of them 30 ft or deeper) and very very uneven ground (you regularly go up and down 15 ft as you clambor over tumulous (lava tubes)).
We use super bright flashlights so we can see distances as well as illuminate the area to find the best paths around obstacles. Since we're 20 miles from any services and any lights (hawaii is VERY dark at night) we often bring 3 or 4 flashlights and plenty of batteries.
We prefer to use flashlights that have a fairly wide field so that it illuminates as much as possible in front of us (and a bit to the sides) without blinding others in the party.
Any recommendations specific to these needs would be GREATLY appreciated since I feel that LED, if bright enough, would be great as it would be lighter and have infinatly better shelf life and battery life.
Anything that is lighter than my 2 million candle power 6 volt rechargable would be a blessing ;))
(btw, before you say it, yes, we do use nightvision too but that is very dangerous to wear and walk at the same time, plus it doesn't do that great a job of showing the cracks in the ground which are often in shadow... though it DOES do great for finding where the flowing lava is ahead of you - the NightOwl M is batteryless and uses squeeze pizeo for power - very neat).
