In addition to the lamp, the battery there is a charger, a small pocket for the battery and a headband, so you can wear the lamp on his head, thus it is also suitable for joggers.
The headband is comfortable to wear and can be adjusted to individual, you can really make good use of and you get relatively little of the heat development.
The cable should be enough for most people to the battery of the lamp on the wrist or on the pants to fix.
Conclusion:
A well-made bicycle lamp with excellent luminous efficacy and a strong 6400 mAh battery.
The clever and practical headband the whole is also suitable for joggers.
As negative I can evaluate only the heat generated by the lamp, this may be a normal occurrence in the performance.
If the LEDs diligently persevere despite the heat generation, is one of the best bike / helmet lamps that I know.
The following is an update after prolonged use or after a lamp failure.
Until then, there are 5 stars
