As I drive through the whole winter off, a good light for me is important. Conclusion of this lamp: Lots of light at a good price. Step 2/3 is very bright, at Step 3/3 the sun rises. Facilitates orientation very. Wide viewing angle. The battery power at level 3 is ends favorably, but also level 2 is sufficient. I use Level 3 only for fast downhill runs, on all other Traks I come up with the first two stages very well. Stretch of over 2 hours are not a problem. The price I find in Vergelich to other lamps of this luminosity very fair.
