The lamp has a very handy case. The rubber also seems to be quite robust. The upper part can be removed and then the view of the LED but which is still protected by a plastic dome. Next you can not do in the upper part. In the middle of the switch is also what is rubberized and is not just so pressed accidentally. Directly above is a small flashing green LED when the lamp is off. Thus one finds the lamp over and above all you also know wherever you can press. In the lower part then are the batteries. The bottom case simply unscrew and remove. 3x D batteries Mono fit in there which make somewhat heavier the lamp, felt twice. But is not a problem. The screw on the bottom case is a bit fiddly. It is important that the two guide lugs are superposed and then install and tighten gently.
There are two suspension points, down on the battery compartment cover / bottom case, a smaller fold-out plastic hook. At the middle part upwards foldable is a robust metal handle is also convenient to hold in your hand.
With the button, you can toggle through the three functions: 1. A strong, very strong 2. A, 3. Flashing, OFF. The light fades in the middle not, it radiates upward and untern slightly stronger and lighter forms a ring.
Unfortunately I can not make any statement how long does the battery charge for a few hours but I think it would be enough.
