I purchased the LD01 because I was looking for a durable and bright light to add to my keychain. Usually Inova or Photon are the first brands that come to mind for this type of light, but in this case I'm glad I did a bit more research because this is a very nice little light. It was also a no-brainer to go for a light that uses triple-A batteries rather than button cells, because I can have this thing back up and running with greater flexibility should it go dead, plus it's cheaper to run.

Pros:
+Small size (about the size of a Chapstick)
+Big power (80 lumens max? Better than most full-size flashlights!)
+Well built, probably will never break
+Uses AAA battery (easy to find replacements and cheaper to run)
+Three brightness settings for different applications/battery conservation

Cons:
-Anodized black finish will wear off pretty quickly when in pocket with other keys/metal
-Low/Medium settings emit a bit of a high-pitched hum (due to ultra-fast flickering technique used to achieve partial brightness, some people may not even notice)
-Can be inconvenient to toggle through medium/low/high settings. Would prefer unit to default to low instead of medium.

Other thoughts:
If you are on a budget (or just don't want to spend forty bucks on a keychain light), go with the Fenix E01 instead. It will provide great performance at less than 1/3 the price of this light.

Even on "dim" this little light puts out plenty of light for walking around in the dark. On "bright" it's bright enough that I can stand in one place and scan my ~10,000 square foot lawn for toys left out. Wow.

Comparing to Maglite, it's roughly as bright as a 3D flashlight (with much shorter run time, of course), or brighter than the AAA flashlights (with longer run time).

Specs:
Dim: 10 lumens, 8.5 hours.
Medium: 27 lumens, 3.5 hours.
Bright: 80 lumens, 1 hour.

Compare with traditional Maglite:
Solitaire: 2.3 lumens, 3.5 hours.
Mini AAA: 15.6 lumens, 2 hours.
Mini AA: 15.2 lumens, 5.5 hours.
2C/D: 36.5-40.6 lumens, 5 hours C, 9-10 hours D
3C/D: 76-82.5 lumens, 5 hours C, 9-10 hours D

(Maglite does not advertise lumen rating or run time for their LED flashlights.)

I have two relatively minor quibbles:
1) Since "dim" is plenty for most uses, I would prefer if the sequence was dim-medium-bright instead of medium-dim-bright.
2) I think (though I am not sure) that I would prefer a pushbutton switch over the twist switch. Not sure where you'd put the button on a lamp this small, though.

Still carrying it all the time, still happy.

Still happy.

Update: The review below refers to the LD01 which has flashing and SOS modes and 80 lumens. If you don't need the flashing or SOS modes, go with the Fenix LD01 instead. It's brighter and has less PWM flicker at the lower light levels.

Original review:
If you're looking for a compact LED flashlight that runs on a single AAA battery and will always be ready and available, the Fenix LD01 is by far the best in terms of light output, beam quality, efficiency, and durability. It's about the size of a ChapStick so you can carry it in the change pocket of your jeans. I've used it as a bike headlight with great results. Other flashlights I've tried give off a dim, poorly diffused, blue tinted beam. The Fenix LD01 provides three levels of very useful white light. It's great for camping. If you store one in an emergency kit, install a lithium AAA battery as they have a long shelf life and won't leak if it ever does go dead. I recommend getting flashlights that take either AA or AAA batteries as they're the most readily available and come in NiMH rechargeable and lithium versions. It may seen like a lot of money to spend on a dinky little flashlight, but it's worth every penny. It will outshine flashlights several times its size.

After 9/11 it became apparent to me (and, I'd warrant, a good number of other New Yorkers) that it would be a good idea to carry around some sort of small flashlight, underscored every time a subway train stopped unexpectedly in a tunnel. It was one of those background amendments to life in NYC that just happened, like the way we react now when a plane flies overhead.

I bought a MagLite Mini and stuck it in my bag. The light seemed reasonably bright, the unit was small and clever with the switch incorporated into the head and being able to stand it on end to use as a candle. I felt a little smug for making such a fine choice.

But I don't always carry my bag with me and the flashlight was too big to carry around regularly in a pocket. As well, because I don't use the light enough, I worried that the batteries would leak. So I took them out. But now I'd have to remember how old the batteries were and replenish them from time to time. The light had now become an end unto itself and not much use to me in a darkened subway tunnel.

A friend gave me a small Orvis keychain light. This solved both the battery problem (some sort of life-long battery in it) and the portability problem but the light was pitifully weak - fine for reading menus but barely enough even to find a keyhole in a darkened apartment building hallway.

Though not as bright as the Mini, the MagLite Silhouette was an improvement over the Orvis (now I could see my shoes in a darkened apartment building hallway), uses only a single AAA battery which I always have on hand to power my insulin pump, and I could attach it to my keychain and as such I'd probably use it more often mitigating the risk of leakage. It felt good in my hand. I congratulated myself for another fine choice.
