I have chosen this headlamp because of good reviews, and I have another Petzl lamp possessed, I thought that it is not a big risk. The lamp looks great, is easy and chic. But what I can not understand: the housing is made of transparent plastic (green). That's why the lamp not only illuminates the way, but reflect the rays on the nose, eyebrow, and finally in my eyes. It's incredible. I need the headlamp in the pitch dark for a jog, and then it is extremely disturbing. Even though I hold the lamp in the hand, has the same problem, and lights up green everywhere. So sorry Petzl, but that's why I would advise against this product, as a design flaw is not acceptable in my opinion.
