Features & Benefits

User Interface

When purchasing a light, you want one that is easy to use even if you are wearing gloves. The Fenix LD41 provides users with a simple to use interface. The LD41 utilizes a dual tail-switch to power the light, as well as cycle through the different modes. Depressing the main tail switch half way activates the momentary on feature. Fully depressing the switch will power on the light. Momentary on will activate the last mode used. The mode switch, which is the smaller of the two, is used to cycle through the various output modes. The best part is with the dual tail switch the Fenix LD41 is ideal for one-handed operation.

Fenix LD41Flat Body Design

There is nothing worse than holding an uncomfortable flashlight. Most users prefer a light that fits comfortably in their hands. They want one that doesn’t feel awkward in their hands. The Fenix LD41 is unlike other lights because it does not offer the traditional round body. The LD41 features a slip-resistant flat body design; making it comfortable to hold even for long periods of time. The flat body design also helps prevent the light from rolling off of smooth surfaces. The fewer impacts the light has the longer it will last.

Technology Features

As technology advances, so do flashlights and the Fenix LD41 is no exception. With the Fenix LD41, you won’t have to worry about dimming lights as the batteries wear down. The digitally regulated output ensures the light maintains a constant brightness. The light also features a low battery indicator to alert you when the batteries are getting ready to die.

Social Proof

After spending several hours online reading through reviews of the Fenix LD4, 1 I have to say it is one that I would highly recommend to others. The Fenix LD41 is one that I would gladly buy because it is one I could rely on when I needed it most. My good opinion of the Fenix LD41 seems to be shared with several other flashlight enthusiasts. Several reputable review sites feature positive reviews of the Fenix LD41. Like other flashlights, the Fenix LD41 does have its flaws, which a few reviewers did take note of. But, even with these flaws, I wouldn’t hesitate to add the Fenix LD41 to my growing collection.
