After some back and forth I decided for this Petzl headlamp and have not regretted my investment in any way. As a beginner run I will now put myself in my first dark season and perforce must jogging just after work in the dark. As already concerns and unease came to know if I trust myself alone through the dark city park. I feel with this lamp but absolutely well, it really lights up everything from - both forward and sideways. Even a Mitjogger benefits with the beam of my lamp. The brightness Senor work top. However, you should of course switch to a street to permanent lighting, since it reduces the brightness with oncoming vehicles that illuminate a course. With a push of a button but the problem is fixed. They will not slip, can be operated easily and recharge and is the weight not uncomfortable, because I like to tend to neck strain. So does running in the dark fun whilst ensuring safety.
