    Busch & Muller fly headlamp

    I just replaced my old dynamo powered B&M lumotec N with the "new" IQ premium fly RT senso plus on my commuter bike, WOW! what a difference a few years of technology makes! It is fair to say it is probably double the light in both intensity and beam size, not a scientific test, just my opinion. The daytime "be seen" feature is good and the beam is bright and well controlled. The only drawback I see is the price, $95.00 from Peter White.

    Thanks for your compelling seat-of-the-pants evaluation. I have been satisfied with the IQ Fly headlamps for several years, but the upgrade to the latest "performance" model sounds worthwhile. The advertised boost in lumens and wider beam for these products is meaningless unless noticeable from a handlebar perspective. I may also change out several rear fender-mounted Seculites for the latest Seculas.

    Looks like a decent bump in performance. Just ordered a Cyo premium from bike24.

    I was reading about them on the PW website and they sounded like a pretty good light. It's good to hear that they really are. Now, if I only had a dynamo...

    In the interim since I posted this I bought a dynamo hub, the 3N72 for $79 on ebay. Not a bad price.

    Z,
    That is the dynamo I run as well, nothing fancy, just works.
    After a month of riding I am still happy with my light, one thing I might mention I ride city streets, that means some streetlights. I think if you ride in the dark there may be better choices for illumination. My concern in the city is "being seen" first, that function is noticeably better, drivers are giving me more space which means they are seeing me!

    Check out my location. I think city kind of describes where I live. I do like to have a lot of light though, enough to illuminate the road in front when I am in one of the very few dark places I encounter, and dark is a relative term. There are no back country roads, just a few parts hidden from the streetlights.

    the IQ reflector use where the LED is on top and so, and facing down, directed beam shape is much better
    As a Bike light, works well.. onto the street, not the other guys eyes.

    Got a low cost Lyt, but found it so narrow a beam once also lowered to my Brompton fork mount,
    became more as urban Be seen light , rather than a see by light

    Got the newer Eyc, with the IQ design,. for the Brommy, and an Ixon IQ battery light for my non Dynamo hub bike ..

    the Schmidt eDelux also uses the IQ reflector ..

    IQ Fly on the fork crown , sitting up fairly high as it does by its design,
    should be giving a good beam pattern, laid down on the street.

    Sounds similar to W Colorado, we sorta have one streetlight in each block, but sometimes one is out, this light covers the need to see.

    I guess you didn't check where I live. I was being a little facetious. NYC is hardly like W Colorado, or even like Denver. There is light everywhere here. There are no truly dark streets, just some have trees that block the streetlamps in my neighborhood.

    At least you have mountains.
