Busch & Müller Lumotec IQ CYO RT headlight with Daylight Running Lights and Standlight for Hub Generators - Black
The IQ CYO "R" series features a beam pattern that eliminates the "dark zone" immediately in front of the rider.
New for 2011, Busch & Müller introduces "Licht 24"; useful light, 24 hours a day. This new feature addresses the issue of daytime visibility for cyclists. The best cycling headlights focus the light onto the road surface. So if you want to use your headlight for increased visibility by approaching drivers during the daytime, you need to adjust the beam upwards. These new Busch & Müller headlights have additional LEDs for daytime riding. They look the same as the other CYO headlights, but with the addition of a row of four LEDs just below the lens. In daytime mode, the "T" setting on the switch, the daytime LEDs are switched on at full intensity to make the cyclist more visible to others. At the same time, the main LED or "driving light" as B&M calls it, is set to a reduced intensity. Senso mode "S" on the switch has the daytime LEDs at full intensity during daytime, and when the sensor determines the ambient light level is low, switches to nighttime mode. The daytime LEDs are dimmed somewhat, and the driving LED is at full intensity. The "driving LED" is the same as in the regular CYO headlights.
The housing is black plastic. There are no chrome versions. Although "Senso" isn't in the name, these are full "Senso" headlights, T (daytime) - Senso (day and night) - Off. And of course, there's a standlight.
40 lux output (Not as bright as N Plus due to larger beam area)
