Busch & Muller the German manufacturer of dynamo power lights has released three new dynamo powered front light models due to come on to the market in late 2012. The models are the Lumotec IQ2 Luxos B 179B (70 lux), Lumotec IQ2 Luxos U 179U (70/90 Lux), and the Lumotec Luxos E 1Q2 179 E (60/140 Lux) (for e-bikes). The other interesting and exciting development with these new Busch & Muller front lights is the inclusion of a USB connection point integrated into the handlebar switch (179U and 179E models only) which allows for charging of mobile devices including mobile phone, GPS units, MP3 players and the like. The lights have a built-in cache battery inside to provide constant charging power.
Whilst I do not see the Busch & Muller Lumotec IQ2 Luxos lights replacing my PedalPower+ Super-i-Cable on my Surly Long Haul Trucker but I can see myself installing a Lumotec IQ2 Luxos U 179U (70/90 Lux) on my Kinesis Racelight Granfondo, my commuter bike as I have a long commute (42 km each way) which includes a fair of riding in the dark in the winter months. Having the ability to charge on the go my GPS or phone or camera is a great feature for me in this context.
Information in English is a bit limited but going from the translations the following provides some early information on the lights. Real on the bike experience is yet to come. German retailers such as Bike24.net and Starbike.com are listing the lights
but at the time of writing do not have stock as yet. Starbike are now suggesting early December, with reports of December 31, 2012. You can register for a stock alert at Starbike.com. As at January 21, 2013 Starbike.com now have stock off the 179B and 179U and Bike24.net of the 179B and 179E. So availability looks like settling down now.

Some user feedback on the Busch & Muller Lumotec IQ2 Luxos 179B and 179U is starting to come in.
At Rose Versand, as at April 3, 2013 there are five user reviews, two on the Luxos 179B and three on the 179U. Four of the reviews are positive and really do not shed much light on the durability issues but a user from Germany, Johannes Bergler has provided a more informative review of the 179U. Whilst he had a few good comments he made a couple of not so good points. The first is that the switch on the handlebar only gives a battery status indication of either fully charged or empty. I must admit this one confuses me a bit as these are dynamo lights, not battery-powered lights and the indicator is meant to show the status of the rear light. It might be a translation issue of course (using Google Translate). If the indicator is of the rear light then on/off sounds right.
More importantly is Johannes second concern and the more serious concern: The failure of the Busch & Lumotec IQ2 Luxos 179U in the rain. As I understand it Johannes light failed in the first significant rain that he met. Not a good look at all when you are relying on the light as a safety device. It will be interesting to see if this becomes a recurring pattern or not. One post at YACF UK forums has also reported his 179U just stopping functioning as well and he is waiting for a replacement.
HappyHumber at the Australian Cycling Forums received a Busch & Muller Lumotec IQ2 Luxos 179U early April 2013 and included in the packaging was an additional instruction sheet which of course is in German. A Google Translate suggests that Busch & Muller are attempting to respond to issues being raised by providing advice on the setup and use of the light.
