Busch and Muller Lumotec IQ Cyo T Review - Intro

After building a DIY longtail cargo bike I needed a front light so I moved my Busch and Muller Lumotec Lyt Senso Plus  on to the cargo bike and purchased a top of the line Lumotec IQ Cyo T to fit on my upright bike. I have been so happy with the otehr busch and muller lights I have bought I didn't mind parting with the money, I suspected it would an excellent light, and it is.

Busch and Muller Lumotec IQ Cyo T Review - First Impressions

 What a lovely piece of kit. Build is very solid switch feels like it is meant to last. Metal bits are stainless steel.

Busch and Muller Lumotec IQ Cyo T Review - Features

The Lumotec IQ Cyo T has got one main powerful LED light source for lighting the road, and four intensely bright LEDs that provide visibility (ie so cars can see you etc.). Two of these 4 LED are supported by a standlight so they stay on when you are stopped. Even these LED running on standlight provide visibility for 3 - 4 meters.

The Lumotec IQ Cyo T is packed with features. It has a daylight sensor which automatically switches between modes, depending on how dark it is.

Stuff off of the box:

• 5 x the minimum level of brightness required by german road safety regulations.
• LICHT (light in german) 24 with daytime running lights - 4 super bright signal LEDs = optimised visibility for other road users.

There are 3 settings for the  Lumotec IQ Cyo T, I have yet to under stand these fully . . the german translation in the instructions is a bit weird.

T -  Head lamp in mode "Daytime Running Light" (DRL) best visibility for for the bicycle during the day or during foggy weather. The driving light in the DRL mode is sufficient to meet german traffic regulations even during teh night and is often more than sufficient. Ideal visibility is guaranteed when cycling on well light streets.

S - During daylight the headlamp runs with full daytime running lights . During dusk and darkness the headlight automatically switches to night mode.

The build quality is very sturdy. Switches feel smooth on operation.

Busch and Muller Lumotec IQ Cyo T Review - Performance

A bright white flood of light will fill the road ahead of you for around 20 meters, because the main headlight is so powerful there is no need to focus the spread of the beam, and as such there are few bright spots / dark spots as is the case with less powerful headlight.

Even the 4 Small Lights Below the main headlight are bright enough to ride by.

The daylight running light (the row of 4 no. LED below main headlight) are extremly bright, and even 2 of these LEDs running on standlight provide visbaility for 3 - 4 meters.

Above pic shows the standlights on the Busch and Muller Lumotec IQ Cyo T which are very bright, again blow but exposure perhaps a little long.

Side view. . .  .not as good as I would have liked. You should compare these to the lumotec lyt before purchasing. I think the lumotec lyt may give better side on visibility.
