The Fenix LD35R flashlight boasts an impressive maximum output of 1,800 lumens and can project a beam distance of up to 337 meters. It features one Luminus STT40 Gen LED along with a COB light strip. This versatile flashlight includes a main light and two side lights, offering options for white, red, and blue illumination. The red light has a Red SOS mode and a red flash mode that can be used as warning signals, as well as a red and blue flash mode to alert those nearby. Additionally, the LD35R is designed with dual-sided 360-degree lighting for enhanced flexibility.

Powered by a 3,400mAh rechargeable battery, the flashlight can run for up to 101 hours. It is equipped with a USB Type-C charging port that has a waterproof rubber cover. Operation is simple with dual metal switches: a rotary toggle switch for selecting lighting modes and an electronic push-button switch for controlling brightness, strobe, locking, and the on/off functions.

Advanced Temperature Regulation (ATR) adjusts the output of the LD35R based on the working and ambient temperatures. This feature ensures that the device maintains optimal performance while preventing the LED from overheating. The output measurements account for the total runtime, including periods of reduced brightness due to temperature changes or built-in protection mechanisms, which may cause the brightness level to drop.

The LD35R has a waterproof rating of IP68 and a 1.5 meter impact resistant.

The LD35R includes: 1 x ARB-L18-3400 battery, USB Type-C charging cable, Holster, Lanyard, Spare O-ring, User Manual and Warranty card
