Property me this Lampenset bought because I go often with cycling to work and the way there also partly goes through the woods. And since I have been working in shifts, this means, of course, I also one or the other drive in the dark times. For that plays along this lamp in the lower price segment, the brightness is quite ok. What annoys me is but very the fact that me already, is canceled by the holder in the 3 months where I now take this lamp the small "flap", which can be removed from the lamp holder again! That's why there's also 2 star subtracted because I already had to buy a new holder specially me! So you can earn money also ..... From this lack, I have now read on many occasions (in various forums and reviews). If I go again, the holder broken, I'll directly buy me another lamp system.
