Battery Options

Output & Runtime

NOTE: The above data has been measured in accordance with the international flashlight testing standards ANSI/NEMA FL1, using 1x18650 battery (3.7V 3400mAh) under laboratory conditions. The data may vary in real-world use due to different battery use or environmental conditions.

* The runtime for High Mode of White Light is the testing result before starting temperature regulation.

Operating Instructions

Battery Installation

Insert battery with the positive poles pointing forward as illustrated in the diagram.

1. Ensure batteries are inserted with the positive (+) end pointing to the head. The DL10 will not operate with incorrectly inserted batteries.
2. Avoid direct eye exposure.

Red Light: Two brightness levels selectable. When the red light is on, tap switch 2 to change the brightness.

Special Mode (White Light Strobe)

Whether the DL10 is on or off, long press switch 1 and switch 2 simultaneously to enter strobe mode. Tap any switch to exit and return to the previously used mode.

ATR (Advanced Temperature Regulation)

With Advanced Temperature Regulation module, the DL10 regulates its output and adapts to the ambient environment, maintaining optimal performance.

Replacing Battery

Batteries should be replaced when the following occurs: The white LED blinks quickly for 2 seconds and automatically lowers its output.

NOTE: Please ensure the surface of the light is dry before taking the battery out for replacement.
