The light output is 10 watts more than modest! As a "headlight" or "spotlight" you really can not call the device now. As I have already experienced better. For the price you can accept this, however. It's just a nice gimmick!
What I do not find acceptable is that the unit has held (about 10 hours) just 9 months for daily use. But what do you expect for just over 10 euros ..... Therefore only 1 star!
