I got the two bicycle headlight headlamp "Luxos B" and "Lumotec IQ Cyo RT Senso Plus Premium" of Busch & Müller. Previously I had a 0815 Hallogenbirne. Actually both headlights are comparable. The Lux 10 more when "Luxos B" fall probably only in the simultaneous comparison. Both headlights both have lit a lighter stain and runherum slightly darker. When "Lumotec IQ Cyo RT" the brightness difference is not as pronounced. However, I had the feeling that this headlamp illuminates minimal wider. The "Lumotec IQ Cyo RT" I liked maybe a bit better from the illumination. But I have decided to use the "Luxos B". The spotlight has in my opinion a little better design and fit visually better my bike. The "Luxos U" with a USB port and "high beam" I have not considered for selection because there is a lithium battery is installed and will be probably broken after a few years.
Can only recommend both headlights. Of course when cornering can not be so beluchtet as when driving straight ahead the curve. But that's no problem for me. The closer the curve is the slower I go, too, and do not need 50 meters visibility.
