B&M recently announced a 100 Lux dynamo headlight called "Lumotec IQ-X"
http://www.bumm.de/produkte/dynamo-scheinwerfer/lumotec-iq-x.htmlMetal housing, integrated cable guide, slightly smaller than the B&M Cyo but is described as having the same broad beam shape as the B&M Luxos. It looks like it is "waterproof" in the same way as the Edelux II.

As I understand it, the on/off button is inside the blue ring. I assume the blue ring also signals whether the light is on or not, and perhaps also a help finding the button when turning off the light in a very dark place.
The metal ring on the aluminium body is used to attach the light to light holder bracket. It also has three small slits that allows for sideways light which is a legal requirement in many countries.
Apparently the ring allows the light to be mounted from the top since the ring can be turned. This will make it easier to attach it to handlebars. Probably some recumbent bicycles could benefit from this too.
Beam shape on a road. It looks like it can easily illuminate the road up to at least 50 meters:
For comparison, here is the "old" 60 Lux IQ Cyo:
The "new" 80 lux IQ Cyo Premium:
What worries me a little is that it only available in a "sensor/daylight" version. I really hope that they don't pack too many modes into the single button since I hate cycling through many modes using a single button when turning off the light.
To think how happy I was with my 15 lux halogen dynamo light a decade ago. The progress in bicycle lights have been amazing thanks to advancements in LED technology.
