Key Features Explained
The five modes include high and medium settings, a yellow fog-light mode, strobe and dual beam. Runtime depends on the selected mode, so the stated maximum of up to 10 hours should not be assumed for every setting.
The built-in battery charges through USB-C. The product is also described for handheld flashlight use, in addition to use as a bike headlight.
What to Compare Before Buying
- Mount fit: The bracket is described as fitting most bikes, but handlebar diameter limits are not provided. Check that the bracket and straps fit your handlebar securely.
- Runtime: Compare your expected ride duration with the runtime for the mode you plan to use. The stated up-to-10-hour figure is not broken down by mode.
- Charging: Consider whether USB-C and the stated 3-4-hour charging time suit your routine.
- Weather exposure: Check whether the IPX4 rating is appropriate for your expected conditions; do not treat it as waterproof protection.
Compatibility, Size and Fit
The adjustable bracket and anti-slip straps are intended for bike mounting, but no handlebar diameter range is given. Confirm the fit for your bike before relying on the light’s mounting setup.
Before You Decide
Check handlebar fit, the mode and runtime you expect to use, and whether the IPX4 rating suits your planned conditions.
