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?"

    I have been testing LED flashlights for 2½ years now. I can say that things are changing fast. Driver technology is being used to make LED flashlights brighter and way more efficient than the "old" days. This is basically a box that sits between the batteries and the LED bulb itself, making sure the LED gets the voltage and current it needs for max efficiency (like a transmission in a car).

    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.

  16. Extended question... by MrIcee · · Score: 4, Interesting
    The question posted is an excellent one. I've often wondered just how good the LED flashlights are for brightness.

    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).

      The halogen beam is zoomable, so you can fit it to your needs. The 5 LEDs are reasonable for watching where you are going, but not for seeing far in front of you. Having the battery pack on your belt/pocket makes it very light on your head, and it's built like a tank. Keep in mind this thing is designed for serious mountaineering, where your headlamp can literally mean your life.

  23. Shameless EverLED promotion by n1ywb · · Score: 2, Informative
    As a distributor for the EverLED, I am a bit biased. But please allow me to briefly sum up why I think the EverLED really is the best LED flashlight solution on the market today.

    Most LED flashlights currently on the market suffer from one or more of these shortcomings
    1. Relatively poor battery life. Most cheapo LED flashlights just use a resistor to limit the current to the LED. This makes the LED only slightly more efficient than an ordinary bulb, and as the battery voltage drops the current to the LED also drops, causing the LED to dim long before the batteries are really dead.
    2. Lack of, or fixed focus/reflector. Most LED flashlights use the optical characteristics of the LED itself to focus the beam. You're stuck with whatever beamwidth the LEDs happen to be, which can be anywhere from 100 degrees to 10 degrees.
    3. Poor design/construction. Most LED flashlights are cheapo plastic. Even the well constructed ones often have design flaws, like the one mentioned earlier that requires a jewelers screwdriver to change the batteries. They might be fine for recreational use, but if lives are on the line, forget it.
    4. Not very bright. Some of the multi-LED array flashlights solve this problem, but in general the small T1-3/4 LEDs used in most flashlights are not exactly the brightest around.

    The EverLED addresses all of these issues.
    1. The EverLED bulb houses an efficient regulated driver circuit, which maintains a near constant current to the LED until the batteries are almost dead, then slowly cuts back so that the light dims gradually, but never totally shuts off. This way you have some warning that your batteries are dead, and even dead batteries will produce some light. See this graph.
    2. The EverLED uses a "side emitter" LED. Instead of a lens, like normal LEDs, the LED used in the EverLED uses a prism to direct the light out the sides in a toroidal pattern. The flashlight's existing reflector is used to focus the beam. If your flashlight features an adjustable reflector, such as the Maglight, you can retain it's use.
    3. The EverLED itself is housed in machined brass and potted in epoxy, so it's probably stronger than it needs to be. It will happily work inside almost any industrial strength flashlight.
    4. The EverLED uses a 1 watt LED. It's up to 10 times brighter than other LEDs, and up to 4 times brighter than a typical krypton flashlight bulb.

    So for the reasons above, plus the fact that the EverLED works with any size flashlight from 1 to 6 cells, pretty much makes it the best LED flashlight solution going. Nobody will touch you with a 6 cell LED Maglight. That's just my $.02

So tiny, so bright, so rugged, and run for hours and hours on one AAA battery. The secret is the tiny built-in DC-DC converter which extracts every last electron out of the battery while stepping it up to a constant current for the LED. The electronics are encapsulated, and the battery chamber is sealed, so it's even waterproof. Really, I think this is the most elegant design possible. Most others require special batteries, or have worse performance, or are excessively complex or fragile. One of mine has been on my keyring in my pocket for a couple of years. It's really scuffed up, but works like new and is only on its second battery, despite the fact that I find a use for it every few days, and can't imagine what I ever did without always having a flashlight at the ready.
