Good choice 40

For 4 years I was using a SIGMA LIGHTster and was very satisfied. Since the wheel is also used in winter and almost every day even in the dark, the battery costs were me then too high, and as an alternative came the Speedster in the election. For 3 weeks, the lamp is in operation, and I am completely convinced. My path leads me by absolute darkness, and here already reaches the lowest of the 3 adjustable lighting levels. After approx. 4 hours now operational in refrigeration had not be recharged. To load a standard USB charger, which probably everyone has, including sufficiently long USB cable is sufficient. The lamp is supplied with a power supply in addition to USB cable.
However, three observations:
1. The power supply is very practical, the cable is a joke, because far too short. Since it can also save the same!
2. The handlebar mount is equally suitable for Speedster and Lighster. Here, however, I noticed that the old fixed bracket sits as the new. The rubber part which surrounds the arm is serrated and not smooth as the Speedster. The more firmly, I use it more as well.
3. The selector switch on the lamp is difficult to operate to fipslig and wearing gloves. Here the Lighster had the advantage.

Otherwise: Clear Best Buy.
