FELD01R4: LD01 LED Flashlight

Fenix LD01
The extremely small Fenix LD01 LED light is not much bigger than the one AAA battery it uses. Its 3 modes allow the user to select the best compromise between brightness and runtime for any given task and to aid in an emergency. The light produced by the Fenix LD01 can be best compared to many flashlights ten times its size.

The compact size, solid reliability and lightweight build of the LD01 make this light perfect for every day carry.

Fenix LD Series
The Fenix LD Series flashlights bring innovation to illumination. Each model offers a great mix of performance and practicality, a truly versatile tool perfect for your pocket, glove compartment, purse, keychain or tool box. A key feature of this series is its ability to use universally available, common AA or AAA batteries (Alkaline or NiMH). It is suitable for travel, home use, emergencies, and all outdoor lighting needs.

Made of aircraft grade aluminum, the LD Series lights feature a durable Type III hard-anodized anti-abrasive finish, digitally regulated output levels to maintain constant brightness, and a toughened ultra-clear glass lens with antireflective coating. All lights are waterproof to the IPX-8 standard.

Flashlight Operation
Screw the light head tightly to turn on the flashlight, and unscrew it to turn it off. When it is on, turn it off and on again within two seconds, it can shift into the next output. The outputs are cyclic. If the interval between the on and off states is over two seconds, the regulating circuit will reset. When turn on again, it will enter into the default output automatically.

Pros: Durability, Brightness
Cons: None
This torch is part of my EDC gear. Not much larger than chapstick. Disappears in the pocket. When you need illumination, this thing is bright. Very compact device, robust design, one AAA battery, VERY bright. Perfect EDC.

Fenix E01 flashlight.
The Fenix LD01 is sa great little light.Little as in it will fit in my watch pocket on my jeans easily.It has 3 brightness settings 3,26,and 72 you the right amount of light for most tasks.It is well constructed and durable and I always get lights that run on a standard battery size,AAA,AA etc.This one runs on one AAA battery.There are certainly a lot of great flashlights out there that run on the "watch" batteries but I really hate spending $15 on replacing the batteries on my flashlight. I admit I owned this same light before and lost it.I have 2 other Fenix lights,the Fenix LD10 and the Fenix E01.Iove both of them.The LD10 offers great lighting for a AA flashlight.The E01 is small like the LD01 but 12 lumens.Plenty for just needing to see in the dark.The E01 is the perfect pocket light you can carry with you anywhere I've found.
