## Before you buy

- The listing says the light is approved, but does not identify the approval or its jurisdiction. It also advises checking local requirements outside Germany before use. The 12 Volts detail conflicts with the technical data's 3.7 V nominal voltage, so treat the technical operating voltage as unclear. The 140 Lumen and 140 Lumens entries differ only in wording. The stated 15-hour runtime is not tied to an operating mode. Check the selected listing for the exact USB-C cable and package contents.
