With its four lighting levels and two flashing outputs, the Fenix LD10 high-performance flashlight is ideal for hiking, camping, and general use.

The LD10 flashlight features a knurled surface to encourage a better grip.
The LD10 is equipped with a Cree XR-E LED bulb with a lifespan of 50,000 hours. The bulb's digitally regulated beam maintains a constant brightness during your activity, so you won't have to deal with a dimming beam while you hike. The LD10 produces four output levels: low (9 lumens), which runs for up to 34 hours on a single AA battery; medium (47 lumens, 6 hours); high (94 lumens, 2.2 hours); and turbo (120 lumens, 1.5 hours). As a result, users have plenty of lighting options for any scenario. Users can even use the flashlight as a strobe, with traditional strobe and SOS settings.

The flashlight is also well built, with a durable aircraft-grade aluminum body coated with a premium Type III hard-anodized, anti-abrasive finish. The construction--which also includes a toughened ultra-clear glass lens with an anti-reflective coating--helps the light hold up to all kinds of abuse. Other features include a pushbutton tail-cap switch; an anti-roll, slip-resistant body design; and such accessories as a holster, lanyard, body clip, rubber switch boot, and two spare O-rings. The LD10, which also stands on a flat surface to serve as a candle, carries a limited lifetime warranty.

Really wish this could be a five star review. This is a great little light, it's just slightly less than life-trustingly reliable. If form and function were all that were required, this would be THE light to buy.

It's size is perfect for when you don't want to carry a full-size pocket light. It's about half the size of a SureFire tactical light or a MagLite.

It also gets points for functioning on a AA battery. With frequent daily use, this lasted a month on one lithium battery. Pretty good.

As an LED it remains cool and the bulb won't pop if you happen to drop the light while using it.

The best part, perhaps, are its 5 options for light. With the bezel moderately tightened, you get 3 levels of brightness at the push of a button, and a slow blinking S-O-S beacon for emergencies. Tighten the bezel all the way and you get the brightest setting and a strobe option. For dazzling opponents, or staging your own rave, I suppose.

In some instances it is inconvenient to have to push the button three times to get to the brightest level. It would be nice for it to "save" the last level used as some other similar models do.

The biggest concern is that it doesn't always light on the first push of the button. It seems the programming for the controls is faulty. There are times when you have to cycle through, clicking the switch 4 or 5 times before it comes on. For a light in the 50-70 dollar range this really shouldn't be acceptable.

I can't use this light where my life might rely on it instantly lighting (e.g. for personal defense situations), but as a tool for ultralight hiking on the trails, daily utilitarian purposes and such it's about the best in class.

I'd buy it again. But only for half the price I paid.

I have carried this light daily in my pocket for years. It is a fantastic size & quite bright for a single AA battery. Nice features with a defensive strobe & the ability to step down the brightness for regular uses. I wish I had the ability to make the strobe the first choice on activation which would make it a better defensive light. It comes with some extra parts which is a nice touch from Fenix. It does include a case (which I do not use) and a clip (which I prefer) and will not roll away with the faceted sides. It is durable enough to be dropped, dunked or mounted. The crenelated bezel on the front is nice (especially since it lets you know before the batteries are dead that it is on if when you put it face down on a flat surface). Using AA batteries is great since they are widely available and cheap to replace when the kids get a hold of the "good light" but then forget to turn it off.

I bought this flashlight after buying a Maglite XL100 and absolutely hating it. The Fenix LD10 is simple to operate, uses a single, widely available battery (AA), is very portable and looks pretty tacticool to boot. I know when I was looking online, it was hard to find an explanation as to how to operate the flashlight, so I'll tell you here. a single click of the button puts it into 3 lumen mode, a slight press of the button and back off brings it up to 30 something lumens, one more time brings it to around 50 lumens, and one last time brings it into SOS flashing mode. If you tighten the bezel all the way, it puts it into turbo mode, where a single click of the button will put it into 100 lumen mode, and a slight depress of the button again will put it into strobe mode. Honestly a very easy system to use once you get your hands on it. The clip is great, but removable if you don't want it. and the Anti Roll ring works quite well with or without the clip. All in all a great flashlight.

Edit: 2 years later

This thing is still my goto flashlight for pretty much anything i need a light for. Tough as nails and very bright. Clip is still perfect on it. I can't recommend this enough.

I love this light! I primarily use it for when I'm walking my dog at night or jogging at night. It comes with a nice little lanyard which is great for ensuring that you don't accidentally drop it. Even if you did, this thing seems very durable. Fenix lights might be made in CHINA but don't you dare let this fool you, they are built like a tank! It runs on one Double A battery which is also a plus. Don't be fooled by this lights size either, this baby is brighter than a mutha!! It also has a GREAT battery life. It's got turbo mode, strobe mode, low mode, medium mode, high mode, and SOS mode. If you are ever walking alone during the night, I reckon this light could be even used as a weapon by blinding your target and running away or following up with a swift crack in the melon with the head of this flashlight (the head has concave-like edges for these tactical purposes, although the Fenix LD20 is better suited for this). One of my favorite aspects about this light though is the clip. The clip is VERY durable and sturdy. One little trick I found on youtube is if you take the clip off and turn it around, it can be secured to a ball cap acting as your own little head lamp! All in all, a great light if you are looking for something small, portable, and BRIGHT. If you want something a little bigger/brighter, get the Fenix LD20. If you something a little bigger/brighter then THAT, get the Fenix TK35.
