Looking for a single AA battery-powered flashlight, I stumbled upon the Fenix LD10. First off, the LD10 has a version with a “+”. The LD10+ simply means that is comes with a pocket clip. The new LD10 features a premium Q5 LED, which is digitally regulated and controlled to provide maximum brightness at all times during the battery’s life.

The LD10 has six levels of output. It has a Cree 7090 XR-E LED, and its output can be selected by turning the bezel. Below are its lumen-ratings and life on each mode.

• 9 lumens—34 hours
• 47 lumens—6 hours
• 94 lumens—2.2 hours
• 120 lumens—1.5 hours
• SOS
• Strobe

The LD10 measures a very compact 100mm x 21.5 mm. The titanium-coated pocket clip on the “+” version is removable, and the glass lens is toughened with AR coating. The LD10 is waterproof to IPX8 standards.

The LD10+ Premium Q5 retails for $53.95.

As posted previously, here are some good reviews for the Fenix LD10—single AA battery flashlight that reaches 120 lumens in turbo mode.

“I was looking for a small flash light to carry on my person daily. I looked into several models, with surefire being the brand I was most interested in. After looking at the offerings from surefire, I decided to purchase the fenix ld10. The surefire g2 led rated at 80 lumens is much larger than the LD10. The LD10 is very small and fits in my hand nicely. It is not bothersome or cumbersome to carry in a pocket. This flash light is very affordable, cheaper than the surefire g2, which is 2-3x it’s size. It is also much cheaper than any surefire light which comes in a comparable size. Overall It’s a great light that is small, affordable, and reliable. I am very pleased, I think it’s tough to beat especially when comparing directly against the offerings from surefire.”

“The Fenix LD10 is similar to the Fenix L1T; both use a single AA battery to produce a stunning amount of light. The main differences are in modes and selecting them. The LD10 starts in either standard mode or turbo mode, depending on whether the front bezel is fully tightened or slightly loosened. In turbo mode you get the highest possible light (120 lumens), in standard mode it always starts in the lowest setting (9 lumens). Other modes have to be toggled by momentarily pressing the on/off switch. The L1T simply has two modes (98 lumens and 16 lumens), chosen by turning the bezel.”

“Basically, if the slightly lower and higher modes and slightly longer promised operation of the LD10 are important, or if the LD10′s ability to stand on its tail is necessary, get the LD10. If none of this is a key, the L1T is simpler to use and a bit smaller and lighter. Both are great flashlights. On high they light up a back yard better than a 5 D-cell traditional flashlight. Pairing either with the Fenix headband is a great way to have versatility and hands-free light when doing projects and such.”
