Description of Busch + Müller Lumotec IQ2 Luxos U Front Light USB - 179ULSR

Gigantic output and new features. The universal LUXOS for the bike. Equipped with a lot of features and clip-on front reflector. Light delight has never been greater.

With the new light and reflector design Busch & Müller sets the bar for Dynamo LED headlight higher than ever: 90 lux, light field twice as wide as before, by a multiple of large, homogeneous maximum. Dynamo generated light penetrates into a new dimension - as wide, so far, so immaculate bright.

The light field, excellent and wide like never before: immediately before the bike, and even next to the bike over to the side of the road beyond. Technology: additional special-LEDs, electronically controlled.

90 LUX Floodlight
The full power of all light sources. Ideal for difficult sections in deep darkness. Be activated by pressing a button. Function on the day: headlight flasher. In darkness: full light.

USB-Recharge Option
USB socket integrated in the handlebar-switch. Loading USB mobile devices (mobile phone, GPS, MP3 player) with USB-power. In the headlights integrated backup battery (see below) ensures constant charging current.

Now you can control your light directly. Because all important light functions can be switched on the handlebars: ON/OFF, flood light, flash light, etc.

Integrated Lithium-Back-up battery
The additional current-memory is used for peak loads and the charging current. Loading constantly on when driving. The charging status is indicated by LEDs on the handlebar switch.

LICHT24 The Daytime Light
Front-firing signal LEDs. At daylight the automatic sensor turns on automatically to maximum daytime running lights, in the dark to maximum drivelight.

Automatically. The special LEDs are targeted at security perception. Can turn off on the handlebar-switch.

Rear light-Monitoring
A control LED lights on constantly shows whether an attached tail light is working properly.
Included in delivery: light incl. cable, bracket, handlebar remote, clip on reflector and USB adapter

The light is excellent in terms of brightness and range, however it's extremely limited in its ability as a USB charger. It should not be relied upon as a source of energy for smart phones, for example. The most glaring flaw is the connection point, which is fiddly and open to the elements. It is also very limited in its mounting options. I'm sure there are better options
Die Lampe hat ein sehr gutes Licht, schön hell und homogen.
1. Das Flutlicht bringt nicht so viel Mehrwert, ein Fernlicht wäre mir viel lieber.
2. Das System ist nicht 100%-ig dicht und die Elektronik anfällig gegen Nässeschäden. Aus meiner Sicht ist der Lenker-Taster mit seiner Schaltmembran die Schwachstelle. Wird dieser undicht, dringt Feuchtigkeit ins System und führt zu Funktionsstörungen bis hin zum Totalausfall. Für mich das k.o-Kriterium. Meine erste Lampe konnte ich erfolgreich reklamieren, die 2. Lampe mit dem gleichen Fehlerbild nicht mehr.
Wer eine All-Wettertaugliche Lampe für Ganzjahresfahrten sucht sollte sich nach einem anderem Produkt umschauen.
Insgesamt für mich eine Enttäuschung für diesen Preis.

The electrical connections for power in and power out are tiny connectors. These are very weak and two of mine bent when I connected the spades for my rear light. One of them snapped completely. Which is rubbish in a light of this price. I could blame my fat fingers, but I'm sure there is a better way of making connections that doesn't fail like this, Shutter Precision managed it on my dynamo hub!

Bike24: Sometimes a product just does not provide the value we expect. This is an unpleasant experience, but also a chance for a fresh start. Please contact the Bike24 customer support and let us look into the issue. Together we can find a solution that meets your individual expectations and requirements best.
The light is an excellent upgrade from my previous Lumotec Fly IQ, installation was fairly straightforward - a small amount of soldering was required because I reused the existing wire from my dynamo hub. The light sits a little lower than the Fly and there isn't room for the clip on reflector between the light and my front mudguard - but I am not in Germany and am not compelled to use that reflector. I am looking forward to using the USB output next month.
Delivery from Bike24 to Australia was pretty quick too (the price inc shipping was 2/3 of the price in shops here).
das Beste im Rahmen der StVo
Für die Einstellung sollte man verschiedene Winkel ausprobieren. Bei dem Powerlicht handelt es sich nicht um ein Fernlicht, der ausgeleuchtete Bereich wird nicht größer, sondern nur heller. Super ist die Breite des Lichtteppichs. Laden meines Smartphones hat trotz eingeschalteter Beleuchtung noch ganz gut funktioniert. Empfehlung von B+M ist Licht aus. Ladefunktion war Hauptgrund für Kauf. Schade, dass man zum Laden noch ein Adapterkabel braucht. Habe mich wegen noch ein paar anderer Kleinigkeiten gegen die volle Punktzahl entschieden. Das blödeste ist die Einstellschraube. 20er Torx ist an kaum einem Multitool. Die Plastikfront ist sehr kratzempfindlich. Bei Montage an der Gabelkrone sieht man die Rücklichtüberwachung kaum.
