dual IXON IQ

Hi,

Last year I commuted through the winter with a single IXON IQ. Part of my route runs along a dark, narrow, two-lane road with no shoulder. This road is quite busy around 5- 5:30 pm, and I found myself wishing for better (or more) light- oncoming headlights seemed to be reducing the effectiveness of my IXON IQ.

I'm considering a second headlight, and was wondering if a second IQ would make sense, given the unique beam pattern (brighter at the top, then a gradual fade). if i stacked the beams vertically, i think i could adjust one a little further up the road, then have the second beam pointed to pick up as the first one fades.

any advice?

thanks,

-steve

Wish I had better advice. I find the IXON IQ, personally, doesn't put enough light on the ground for me.

Actually, I just though of it - I don't think putting one in front of the other would work very well. They have a shaped beam (brighter on the top) so that it lights the road evenly. I don't think it would light the road very evenly if they weren't aimed exactly the same way.

However, if you just want something brighter with the same beam pattern, I would expect that simply setting them up with exactly the same angle would work. Just point them both a little farther down the road.

Or, you just go all out and get something more extreme like a Seca 700 - haha. :-)

(It's the only other non-dynamo shaped beam light I know of. Not sure if it's shaped as nicely as the Ixon, though)

And then there's the Lupine Betty and its shaped beam. I would imagine their cheaper (well, cheaper for a Lupine) lights have shaped beams as well, but haven't checked out their specs.

I'd really love to know of another battery light that has a well shaped beam, but from that page it just appears that the Lupine Betty just has the standard "flashlight" style beam. Could you point out where it says or shows otherwise?

Would love to know of another lighting option... :-)

I would think that running two Ixon IQ side by side would work well. I'd probably try overlapping the beams side by side, with about a 50% overlap, but aimed at the same height. This appears to be the way Busch & Muller show pics of the Ixon IQ Speed when used as a dual head setup.

Sorry for the delay. This is from Lupine Betty home page, http://www.lupine.de/web/en/products/lightheads/betty/ (click the "Electronics" header at the page).

Our lens was customized and developed by Lupine; therefore it works alot more efficiently than a standard optic. Our own lens made it possible to tune the beam pattern and provide an excellent light for night rides.
Not sure if that translates to what you mean by a "well shaped beam".

Thanks for writing back! :-)

I see that, but I think it's mostly marketing hype. From this review, the beam appears to to be the standard flashlight style beam (round):
http://reviews.mtbr.com/blog/lupine-betty-12/

What I meant by "well formed beam" is one that *evenly* lights the road surface. For example, the Lumotec Cyo puts out less light close to the bike and more light farther away. The result is that the amount of reflected light that comes back and hits your eyes is equal on the farthest part of the beam to the amount of light reflected by the closest part of the beam.

It (IME) makes it way easier to actually see with the light.
