With regard to the correct bicycle lighting, the legislator is taking a somewhat strange approach: Less lighting on the bicycle therefore seems to be more relevant than light that is too bright. There is no other way of explaining why matt incandescent lamps powered by the braking 3 W/6 V side dynamo are allowed, but why a large number of bright LED spotlights can only be used as helmet lighting because they do not have the necessary K number, i.e. the StVZO have approval.
In action
However, there are manufacturers who manage the balancing act between admissibility and a high light output. One of these is Busch and Müller. With the battery light Ixon IQSpeed the lighting specialist has a lamp in its range that, thanks to its 50 lux, will not let you down even on a pitch-dark night. It is particularly impressive that the lamp is also switched on during normal training use outside of town Driving on sight allowed and can be reduced to 10 lux luminosity in built-up areas. See and be seen is with the Ixon IQSpeed definitely no problem.
However, the situation is different in the forest. Because while the light makes an extraordinarily good impression on the road, the cone of light here seems a bit too small to ride root-strewn singletrack at the usual speed. Normal forest paths, on the other hand, do not pose a problem for the lamp.
The assembly of the light, which is extremely light at 85 grams, is beautiful. This is relatively easy to do. The handlebars are mounted using a strap, which provides the light with a secure hold regardless of the handlebar diameter. The supplied battery can also be attached to the frame or stem using a strap. The supplied spiral cable has solid plug connections and thus ensures a permanently good power supply. It is also positive that the electronics of the battery and charger prevent both deep discharge and damage to the power storage unit due to recharging errors. The charging process takes a total of six hours. In relation to this, there is a light duration of up to ten hours at 50 lux and up to 50 hours at 10 lux.
Conclusion
Busch and Müller has with the Ixon IQSpeed created a lamp that is beyond almost any doubt and that lives up to its slogan IQ nothing but light therefore largely fair. Because while it presents itself as a reliable and safety-giving companion in everyday life, it only allows unrestricted use in the forest to a limited extent.
