Said in advance: for the price and the quality fine. I've tinkered the headlamp on my helmet to ride MTB Night Rides through the dark forest. If all 3 LED's are on, so does some light from one or the other riders like a moody Lampingnon. The operation of the individual light levels has been reviewed already sufficient, so I'm no longer a fact. The LM 5000 must not be taken too seriously - but the 3 spotlight together do the trail in front of a very bright, the batteries have been kept well -. 2 degrees outside, changing between 2nd and 3rd stages, 2.5 hours on the road and still about half full (lt. charger). Yet, I think 2 batteries in reserve. Speaking of batteries: Somewhere in the advertising text is advertised with waterproof ... So the cover of the plastic container is a "labbe Riger" rubber coating, which I would not necessarily ascribe waterproof. Maybe he keeps in moderation from rain. The light unit and especially the cornering power cables make but a good and high-quality impression. The longevity of batteries I can not say anything yet. What is certain is that such batteries with such a high charge capacity already expected to account for at least half the price. Savings were also on the power supply. War in the price probably no longer there. I had to define myself - is ok, you can use for other things. Conclusion: For the price - strike, you can not go wrong. The 5 star I would have given when the closure of the battery box valent and at least of the same material as the rest would have been.
