Good, interesting by motion.

The appearance is already listed in the Amazon description well:
A head-mount lamp. The front, there is a push button in red color, which is arranged above the lamp. By means of which it can be changed by pressing the instrument is turned off at the main bright light. This is a LED with a large reflector, then off via motion detector and is re-connectable. Repeated actuation of said pushbutton bright LED disabled including motion again. And the lamp is off. Pressing the push-button twice in quick succession, then lit two small, white LEDs. These take the batteries to a lesser extent. And hide less when the brighter light is not necessary. You pressed the button again after fairly long seconds, then the head lamp is turned off again. At three times pressing the red button, the two small, white LEDs will flash. Pressing deactivates the flashing, and the headlamp is then turned off. The motion itself is only in connection with the main bright light.

Opposite the front lamp is an onboard battery compartment mind. In this integrated another red button. In order to turn a red LED as a backlight. When you double-press of a button, this red light may flash. And a few seconds after interruption of the last operation
can be turned off with a single keypress again the red LED.

EXPERIENCE

In addition to sporadic use I used this light for about a month, a day for approximately 8 to 10 hours, at temperatures of about + 5 ° C to -10 ° C. Necessary thus was a frequent opening and closing of the battery compartment to the battery change. As a result, broke one of the two "noses" without further violence from, solely through the normal use conditions. An improvised repair was performed using cable ties, to go any further function of the closure was given. Otherwise, however, the battery compartment is well thought out. It fits ergonomically to the head, has a good seal, and a captive of the innovative cover is given. Overall, a very good weathering resistance is given.

Both switches for rear light and headlamp are quite small. This is the compactness of the whole to good, but difficult as does the ease of use. An adjustable tilt of the lamp at the front is an advantage. Frequent recourse which allows the automatic latching lock with time to lighten up. As far as durability Einstellmögichkeit, the elastic belts are good. Sutured to the lamp, this exchange is not provided. Frequent application and removal of the headlamp lets the belt lose their strict form. Together with dirt, aggressive media and refrigeration the shelf life is somewhat reduced, the rubber loses its elasticity.

For occasional use of such lamps it is rather an advantage that batteries and lamp form one unit. In my view, well balanced, both to keep in balance, and is "portable", overall not too heavy. The belt upside is positive. Many Headlamps do not have that. He gives more stability against sliding. The lamp can be combined with hoods or other headgear.

THE MOTION SENSOR

What aroused my interest in the lamp:
The motion detector.
Since the activation and deactivation of the main light would by sensor. About 15 centimeters in front of this one touches with the hand from left to right, or from right to left, for contactless switching. This also works. But why it needs a such a non-contact switch with a headlamp? What purpose does it, a few centimeters away from the actual switch to operate the headlamp? First, it is not really necessary for a head lamp, tucked to remain in stand-by mode in bag or backpack makes the standby state of the motion makes no sense. Because the lamp on and uncontrolled conditions may exist. The batteries / accumulators are claimed unintentionally. So would the effect of battery savings, and simplified operation with applied and Turned on lamp. Then as if gloves are worn or the hands are too dirty / wet in order thus to take to his forehead: Okay.

However, the motion detector reacts not only to their own hands, but is equally applicable to many other things that come too close to him, foliage, branches, climbing ropes, their own arms and tools in overhead work. On construction sites, sometimes steel bars, hanging cables, wooden slats affecting the motion sensor. Now, because of the light beam has the same direction as the sensing range, so can already extinguished unintentionally the light in the near viewing an object. For example, when reading small print, the view in map, while turning the head on scaffolding near a column: The lights go out, without wanting it.

In becomes weaker state of charge of battery / batteries of motion prematurely stopped working. And it only remains the operability by the on-off switch. Finally: The motion well-intentioned, and interesting! However, too little practical, and hardly necessary (in my opinion at least).

The ability to switch the front, white light: advantage is that there is a strong and subdued light. This second light are two white LEDs without reflector. Switching can increase the service life of the battery / batteries. At the same time the main light is very flashy, so it can sometimes hide other people.
In addition, a flashing function of the attenuated light is a further addition. Only: What for? Spectacular as a selling point, there has been little actual relevance.

The tail light: A nice addition. With optional permanent and flashing red light. The relatively weak LED and low beam angles unfold no enormous signal effect. To be seen, high visibility clothing or real taillights with integrated reflectors are more effective.

CONCLUSION

For professional use in rescue, or at climbers industrial climbers not first choice. Yet achieved this headlamp for which it was intended: to provide Bright LED light, combined with hands-free and comfortable to wear for the user.

To be fair, to be awarded: The lamp is relatively inexpensive. And the filigree execution while wearing no to rough use bill, but it is all the more benefit of compactness and weight saving of the whole.
At a cost of 20, - to 30, - Euro, the lamp is priced as high in the middle segment, and has a aktzeptables
Price-performance ratio.

A head mounted lights generally are an interesting alternative to conventional flashlight. And suitable for many applications in the home, for DIY, hiking and other activities. This headlamp, I would not buy, but instead the related model without motion. Because the sensor on the front a bit disturbing and the battery compartment baldig wore out, three star rating as.
