extreme Hell, well thought out and well suited for joggers

The frame of the lamp is made of metal and very stable, the battery is connected to a plug with the lamp.
Once the connection is established to show three green LEDs on the battery level on the lamp, the display can not unfortunately off.
Therefore, you should always pull the plug when not in use.
After about 2.0 hours of continuous operation, the display showed another 2 LEDs therefore holds the 6400 mAh diligently through!
And the lamp makes even on the smallest stage an extreme bright light (as I never before looked at) and also the light cone is more than adequate.
It has a really good illumination with the bicycle lamp.
With so much power, the lamp is in continuous operation, of course, warm, dangerously hot but fortunately not.
The fix the lamp works with O ring, this can be confusing for inexperienced at the start, after a moment's thought but logical.

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
