Ixon IQ Speed: Light, bright and compliant

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 to strike a balance between legal compliance and high light output. One of these is Busch & Müller. With the Ixon IQ Speed rechargeable light , the lighting specialist offers a light that, thanks to its 50 lux output, won't let you down even in pitch-black darkness. Particularly impressive is the fact that the light allows for safe riding during normal training sessions outside of town and can be reduced to 10 lux for urban use. Seeing and being seen is definitely not a problem with the Ixon IQ Speed.

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

With the Ixon IQ Speed, Busch & Müller has created a light that is virtually beyond reproach and largely lives up to its slogan "IQ - Nothing but Light" . While it proves to be a reliable and reassuring companion in everyday life, its unrestricted use in the forest is somewhat limited.
