  • Charging: The LD15 features a built-in USB-C charging port for convenient recharging. A full charge takes approximately 2.5 hours.
  • Battery: It uses a single 18650 Li-ion battery (not included), giving you ample power for extended usage.

Beyond these primary features, the LD15 also offers a few additional benefits:

  • Strobe Mode: For self-defense or signaling purposes, the LD15 incorporates a strobe mode that can disorient potential threats.
  • Lockout Mode: To prevent accidental activation, the LD15 includes a lockout mode that disables the light.
  • Reverse Polarity Protection: This feature safeguards the flashlight from damage caused by incorrect battery insertion.

The Fenix LD15 is a well-rounded flashlight that strikes a balance between power, portability, and durability. Its versatile output levels, convenient charging, and robust construction make it an excellent choice for a wide range of users, whether for everyday carry, outdoor adventures, or emergency preparedness.


The Fenix LD15 delivers exceptional performance, exceeding expectations for a flashlight in its class. It boasts a powerful output, reaching a blinding 1,000 lumens on its Turbo mode. This brightness is more than adequate for most tasks, including camping, hiking, and even tactical applications. The beam pattern is well-defined, with a bright central hotspot surrounded by a gradual spill, providing excellent illumination in both close and long distances. The beam quality is also impressive, offering a clean and crisp light without any noticeable artifacts or hotspots. Notably, the Fenix LD15 features a smooth, progressive dimming system, allowing for precise control over the brightness level. This is particularly useful when navigating in dark environments, as it prevents sudden changes in light intensity that can strain the eyes. The flashlight’s throw is impressive, reaching up to 250 meters, making it ideal for long-range illumination. This is particularly useful for searching for objects in the distance or signaling for help in emergency situations.

Battery Life

The Fenix LD15 boasts a respectable battery life, powered by a single 18650 Li-ion battery (included). On a full charge, you can expect a runtime of up to 100 hours on the lowest setting. However, this runtime is achieved using the included 350mAh CR123A battery, which isn’t ideal for frequent use. If you’re using the 18650 battery, the runtime will be significantly shorter, especially on higher settings.

For example, on the highest setting (1000 lumens), the runtime is around 1.5 hours, which is decent for a compact flashlight. You can also opt for the Turbo setting, which delivers a powerful 1700 lumens for a short duration (about 1 minute and 30 seconds).

The flashlight also features a handy battery level indicator that will alert you when it’s time to recharge. You can charge the battery directly in the flashlight using a USB-C charging port, which is a welcome addition for convenience. The charging time is about 3.5 hours, which is reasonable.

While the battery life is decent, it’s important to note that the runtime on higher settings is relatively short. However, the ability to quickly recharge the battery using a USB-C port makes up for this to some extent. Overall, the battery life of the Fenix LD15 is satisfactory for most users, especially if you primarily use it for short bursts of light or on lower settings.

User Interface

The Fenix LD15‘s user interface is straightforward and easy to use. It features a single button on the side of the flashlight that controls all the functions. A quick press turns the light on and off, while holding the button down cycles through the different brightness levels. The flashlight has four brightness levels: low, medium, high, and turbo. The turbo mode is incredibly bright and is ideal for situations where you need maximum illumination.

The Fenix LD15 also features a strobe mode, which can be activated by quickly pressing the button twice. The strobe mode is useful for signaling for help or deterring potential attackers.

The flashlight has a memory function that remembers the last used brightness level. This is a handy feature that allows you to quickly access your preferred brightness level without having to cycle through all the options.

Overall, the user interface of the Fenix LD15 is intuitive and easy to use. It’s simple enough for anyone to use, yet it also provides all the necessary features that you would expect from a high-quality flashlight.
