• USB-C charging makes it easy to use on the go

• Protection class IP68 makes the flashlight suitable for harsh environments

• Good equipment and accessories

Notes:

• With intensive use in Turbo mode, heat generation becomes noticeable – the built-in overheat protection activates and the output may be reduced.

• For optimal runtime and safety, it is recommended to use the included battery or equivalent protected 21700 Li-Ion batteries. Other battery types (e.g., 18650) are not permitted.

• Due to the high output, the light color is rather cool white (~6,100 K) and may be perceived as having a greenish tint by some users.
