Standlights - IQ Cyo vs Lyt Senso

Standlights - IQ Cyo vs Lyt Senso - Intro

This is an observational right up. A comparison of the two Busch and Muller Head lights I have, and a comparison between the stand lights on each model.

So below we have the budget  Busch and Muller Lumotec Lyt Senso Plus (on the left), and the top of the range Busch and Muller Lumotec IQ Cyo T on the right.

Standlights - IQ Cyo vs Lyt Senso - Pictures

The pictures are fairly self explanatory.  

 In day light the difference is very pronounced with the Busch and Muller Lumotec IQ Cyo T being seen very clearly. The light colour being very white, makes it stand out very well. The more yellow light coming from the Busch and Muller Lumotec Lyt Senso Plus is not as noticeable.

Things balance out a bit more  in the dark, the  Busch and Muller Lumotec IQ Cyo T has it stand lights mounted in a separate housing so they do not illuminate the entire lamp housing. The Busch and Muller Lumotec Lyt Senso Plus has its standlight mounted close to the main bulb and as such the entire lamp housing is illuminated.

Standlights - IQ Cyo vs Lyt Senso - Conclusion 

So to conclude I would say that for a daytime cyclist, it is worth spending the extra on the Busch and Muller Lumotec IQ Cyo T, 

as its extremely bright light is piercingly visible in virtually all lighting conditions. If however you want to be kinder to motorists then opt for the less expensive  Busch and Muller Lumotec Lyt Senso Plus . 

The "Cyo" is soo bright I can't help but feel it dazzles on coming motorists, remember this is only the standlights we are seeing here, when pedalling along both would be a lot brighter. The Cyo would chuck out around 5 times more light. Which for city riding is excessive.

  1. Nice write up. If your lights are set up correctly you are not going to dazzle anyone. The Cyo has a focused beam pattern that, correctly adjusted will not dazzle other road users. Some pictures of the beam pattern on the road would be good here as well as images of the lights seen from driving/riding heights. Unfortunately the people that dazzle road users most are the ones with their lights positioned as if in a Jean Michel Jarre concert

  2. What a good French name spelling ability you have, spell checkers not going to help with that one!

    I will try and do some beam videos, photos of beam have not been very successful.

    The Lyt has a very focussed beam, but the daytime running lights on the Cyo are very bright and unfocussed.

  3. I have the Union 35lux dynamo front light (from dutch bike bits) - that's pretty bright too, and also has a standlight, has a good reflector shape (the beam is best described as like a wineglass on the road, with a pretty clear cut-off to prevent dazzling oncoming drivers/other cyclists), and costs under 20 euros.

  4. Looks like a good light you union one, and thank for the introduction to dutch bike bits, I'll have a look on there next time I'm looking for bits. Have you tried - very cheap for certain bits. A reflector is good, they do a "cyo" with a reflector, should have scrolled down a bit in ebay before I bought my one. :-)
