5.0 out of 5 starsGood EDC flashlight to carry on your person
By Richard Gary on October 27, 2009
Color: Black Verified Purchase
The Fenix E01 is so small and light that you are likely to keep it handy, which makes it more useful than the flashlight you left home. Mine weighed in at approx. 0.95 oz. with the battery installed. The body diameter is about the same as an AA battery (it takes one AAA battery), but about 1/3 longer. It would easily be at home on a keychain if you like keychains with extra things hanging off them. It also will quite comfortably fit in a pocket.

Of course, it's a natural for a purse or fanny pack. Another reviewer commented that the reflector collected lint, which I didn't understand until I got the light. There is no lens covering the reflector. Therefore, if the flashlight is knocking around in a purse, I could see how the reflector could end up collecting lint. On the other hand, there is no lens to crack or get scratched up.

The light turns on and off with a twist of the ring surrounding the reflector. There's no button to push. There is no high or low beam. It's simply on or off.

Given some of the earlier reviews, I expected this light to be brighter than it is. I tested the light on an unlit staircase at night and found that all seven stairs to the landing were well illuminated. The corona around the hotspot covered the entire width of the steps. Going outside, I found the light to be adequate for illuminating a path while walking outside at night, but don't expect it to "throw" its beam any significant distance. There is a hotspot in the center of the beam, but more even and wider than the hotspot from an incandescent mini-MagLite. The hotspot has a lavender tinge to it, but the corona is fairly white.

The flashlight is designed so that it can be stood on its end and used like a candle, with the beam aimed at the ceiling.Read more ›

5.0 out of 5 starsSimply the Best Personal Emergency Light
By Jersey Mike VINE VOICE on July 12, 2009
Color: Black Verified Purchase
There are brighter lights, there are larger lights, and there are much costlier lights. I know, because I own all of the above and many more. But, this little gem cannot be beat for a very lightweight, bright-enough keyring light that you can always have with you, that you can turn on and leave on for over ten hours with constant brightness, and then still have another five hours of fading but still usable light to read a map with or signal with. All this for the cost of a single AAA battery.

This is the light to keep in your pocket all the time. And, at this price, you can afford to keep one for each family member in case of power outage or other emergency. It's as simple as that.

4.0 out of 5 starsGreat little flashlight for everyday carry
By Mike on May 7, 2010
Color: Black Verified Purchase
I was looking for an LED companion for my Maglite Solitaire. Some people say the Solitaires are great, some people hate them. Truth is, mine fills a niche. But on to the Fenix.

Fenix and 4Sevens have done some amazing things with single AAA "keychain" flashlights in recent years.

With Fenix's E01, L0D, and LD01 and 4Seven's Preon I, they've introduced us to a new era in single AAA flashlights.

I have a 1977 Eveready "Little Commander" single AA flashlight. I'd estimate it puts out around 0.5-1.0 lumens. A single AAA Maglite Solitaire will put out 2.3 lumens (for around 2-3 hours).

This wonderful little Fenix E01 puts out about 10 hours of 10 lumens (so-called sunlight mode) and about 10 hours of, well, something less, for 10 more hours (so-called moon mode).

Remember how I said the Maglite Solitaire still had it's place in my routine? Well that place is reading while my wife is asleep next to me. The Fenix is much too bright for that, and I don't fancy keeping a dying battery on hand so it'll run itself in "moon mode". I wish they'd include the lower mode at will. One thing I absolutely love about the 4Sevens flashlights (oddly enough this feature is NOT on the Preon I) are their "moonlight" modes, which on their CR123 lights put out 0.2-0.4 lumens for around 30 days. Now that's a nice feature. I would honestly never have said I'd only need 0.2 lumens, but I see the benefit of it now.

Back to the E01.

It's very bright, very well built, and very affordable. You can pick up a Maglite Solitaire at Lowe's for around $7 including tax. This ran me $11.Read more ›

5.0 out of 5 starsGood keychain LED
By Bandit on February 28, 2009
Color: Black Verified Purchase
Fenix offers two keychain LED's. The E01 is a good light that I'm happy with, I also bought the Fenix LOD for another set of keys. If budget price is what your after in an LED, get the E01, you won't be disappointed. If your looking for the brightest and different light settings get the LOD, more money but a far superior light.

4.0 out of 5 starsNice, Simple Light
By JNieporte TOP 1000 REVIEWER on May 6, 2013
Color: Grey Verified Purchase
The Fenix E01 is a simple, one-mode twisty. It costs around $12. What should you expect?

Expect a good, basic flashlight. The E01 is made of durable aluminum, and has been described as "bomb proof" by flashlight aficionados. The body tube is one fixed piece with the tail, and has some nice knurling on it. Be advised that the anodization wears off quite quickly if it's rubbing against things like keys or pocket change. The grey color is actually very close to a faded olive drab. A simple split ring is included so you can attach the light to something, and it goes in the one open lug on the tail. This also allows the light to stand on its end while in use, in effect giving you a "candle". The E01 is quite compact at 2-3/4" long and 1/2" in diameter.

The LED is a white 5mm Nichia, and all of the E01s I've seen tend to have a blue-ish, blobby tint to them. Output is 13 lumens, but this isn't a pocket rocket. It's made for long runtime. I've gotten 30 hours out of a fresh AAA alkaline battery. A no-name heavy duty (read: cheap!) battery is provided. This light will also run for a while on your almost-dead batteries, so that's good. The head twists to turn the light on. Tighten the head to turn on, loosen it a 1/4 turn to turn off. One-handed use is easy. The reflector is a dulled matte aluminum finish, regardless of the color you choose. There is no lens on the E01.

If you want the beam to be better, just get some fine steel wool and rub the LED bulb itself. Then the reflector. Blow out the debris and use a flattened Q-tip to get in the crevices.

The E01 has been a staple of the flashlight community for a while, and it's easy to see why. Again, this isn't the light if you need output or throw, but it does very well as an everyday-use item that will run a long, long time on one AAA battery.
