Busch & Muller strike again with the new Luxos front light which is the first Lumotec with the new ground breaking IQ2 technology. Busch & Muller have designed a new combined light and reflector which has a light field twice as wide as previous LED head lights. The Luxos illuminates an area that is several times larger with maximal homegenous output. In Busch & Mullers own words; "So wide, so far, so pristinely bright'.

The new light provides a very wide range of light, both in front of the bicycle and to the sides extending beyond the edges of the road and over 30 meters in front of the bicycle thanks to the additional LEDs which are managed electronically.

The flood light option can be used in pitch darkness when negotiating tricky road sections etc. It is activated by using the push button on the handlebar. The push button allows you to control your light directly and easily; including on/off, flood light, flashing full or standard output.

It's possible to charge USB devices via the USB socket which is integrated into the handlebar push button including mobile phones, GPS and MP3 players etc. This is done by utilising the integrated lithium cahce battery which supplies constant voltage.

The integrated lithium cache battery is used for peaks of demand as well as charging and acts as an additional energy storage unit. It recharges continually when cycling. The charging status is indicated by an LED inside the handlebar push button.

The Licht24 daytime running light has signalling LEDs shining brightly forwards. A sensor automatically switches between day and night mode. If you look closely at the front of the light at the top you will see the additional LEDs with their own reflectors which provide the panorama light at close range and Licht24 light.

A control LED is situated inside the head light which continually shows whether or not a connected rear light is functionally correctly.

ConsBig and heavy
ProsGood light spread, and USB charging
My first thoughts were that it was a bit big and clunky, and rather heavy.
When I put it on the bike I was really impressed! The light output and spread is superb, the floodlight excellent for tricky descents down dark lanes, and I had no trouble being able to charge up my phone on the go from the USB adapter.
It does take a while to set up - if you run a rear dynamo light you HAVE to open it up and disconnect the Earth that connects to the fixing bolt - you may have to bend out the copper strip. If you don't do this, the dynamo wheel will do weird things, such as power itself from the stored capacitor charge! Electric bike on the cheap!

Prosbeam and charging
Schmidt son28 dynohub with luxos U. Owned for 18 months. at first, using the original 3 foot long charge lead for my tablet ( galaxy 7 inch) , the setup wouldn't charge my tablet, however this weekend, by accident I had to buy a repalcement lead , this lead is only about 6 inches long & charges the tablet without a problem during daytime use without the lights on. RESULT. the lead was £7 from tesco, has a USB one end with 3 tails on the other end. ( micro usb/ mini usb / iphone 4 (samsung) & is all white ) that is what I wanted, the lamp is excellent at night time as long as the other riders with you don't have the new 1000 plus lumen battery lights as they wash out your light. The output from the dynohub isn't enough to run the lights & constantly power the tablet.... as i think 1amp is the quoted output from the switch USB socket at 5 volts. Now i'll upgrade the connector cable from the hub to the lamp, from the bell wire supplied to minimise any more current loss. report to follow

Will This Fit My Brompton M6R To Replace My Lumotec Lyt
28 Aug 2015
I am planning to purchase this as replacement to my B&M Lumotec Lyt which came as original component of my Brompton M6R with Shimano Hub Dynamo.

Since I see the Luxos IQ2 is a bit bigger than the B&M Lumotec, I am afraid the new light will interfere with the front baggage of the Brompton.

Also, is it possible to use the same wiring configurations already installed with the the current light system and just replace the headlight from the Lumotec to Luxos?


SJS Customer Service:

If this Luxos U light is fitted with the Brompton specific bracket then it will fit without interfering with the luggage, the amount of clearance is very slim though so you will have to be careful when mounting it. As both lights use spade terminals then you should just be able to change out the head units without the need for re-cabling the entire system.

What Rear Light Will Work With This Light?

Version With 95Cm Wire To Switch/Usb Port?
30 Jul 2014
I have a Yuba Boda Boda with the "bread basket" and light is installed to it's front side.

There should be three versions to my knowledge 45 cm, 95 cm and 160 cm.
SJS Customer Service:

As far as we were aware there was only the one length available. The length of the ones we have in stock are 60cm. This is the only option available from our UK supplier so this is all we can order unfortunately. I cannot find any mention of there being a different cable length on Busch and Muller's website or in any documentation they provide.

Schmidt Son Delux Dynamo
24 Apr 2014
My Thorn Nomad MK11 is fitted with the above Dynohub, will it generate enough power to charge the headlight so that I can charge mobile phone and a Satmap GPS?
Thank you.
SJS Customer Service:

The Delux was originally designed as a faster rolling lower resistance hub only designed for lighting. It can be used for both charging and lighting but the speed will need to be a lot higher to generate the necessary power for both, we have not tested it with the Luxos light unfortunately so we can't say what this speed will need to be or if there is anyway of reducing the lights output to provide more power to the charging port.
