This head lamp that their focus in flood heritage Reich (90% of my applications) and the battery charge status is notifies, quite useful not only as a head lamp. Detached from the headband can keep the compact lamp well in hand, setting them up or lay. It only lacked a clip in order to use them more universal can. Another slight drawback is the fact that you have to turn off the lamp very focused, otherwise you moved when you turn off the last mode. However, this is not so bad. If you should not be blinded in a special situation, one can start a precaution in the very useful red-light mode.
Update: As a few reviews do not fit any battery, it may be important to know that the white Solarforce 18650 fit very well with 2400 mAh. It only fit batteries that have a nipple at the positive pole.
