First long ride with my Luxos (U version). 600km with a complete night of riding and a second night with 4 hours of riding.
I fitted it to the bike a week or so ago. Nothing much to say about the fitting if you are used to a Cyo (bent bit of metal to go on the fork crown). It is quite a lot larger than a Cyo - quite huge really.
I also took the opportunity to start testing running a small rear light off the dynamo as well - I run a battery operated fibre flare as well, so I just wanted something really small that meant I don't need to stop to turn on rear lights etc. - I went for one of these
http://supernova-lights.com/en/products/e3_tail_light2.html - it's tiny but very, very bright. It doesn't have a standlight - but when combined with the battery lights, that's not an issue.
Anyway - back to the Luxos.
I'd tested the charging side a little already - as I still have a slight mistrust of it all, I don't charge my phone or GPS directly with it - so I charge a battery pack (which costs £25 rather than the many hundreds of a phone or GPS). I run a SonDelux - which needs more speed to get enough oomph to charge things. This is not a problem in audaxing as it all works well if you are riding along at 20kph+ - I guess it is a challenge for tourers with a lower speed (but the higher weight of the regular Son is less of an issue in touring). The charging seems to work really well. As I did with my E-Werk, I only charge during the day - I don't think the light and charging work together well.
So the light. Well - it's flipping bright, well shaped and, frankly, astonishing. End of review!
No - it's quite something. If you're used to a Cyo R, then it has some of the same characteristics with a sharp cut-off at the top. But it's a lot wider - see
http://www.peterwhitecycles.com/headlights.asp for photos - it's just incredible. The light fills in all the holes at the side of the road that the Cyo missed.
There's a slight hot spot in the centre top of the beam to really see into the distance. I didn't get flashed at by any motorists - so I think it passes the dazzle test well (assuming you mount it without pointing it upwards).
As you slow down, the light at the top of the beam dim down and the stuff nearest to you gets brighter. It is all quite clever really.
It does get a bit flickery at very low speeds (probably again related to the SonDelux). But nothing show stopping - if you're going slow uphill it still works.
A press on the handlebar button turns on the boost mode - this is powered by the cache battery - so doesn't last forever (I don't know how long - I should have left it on to test it). Great for downhills.
All in all a fabulous light - it really does give me more confidence than even the mighty Cyo. It's spendy - but when it brings USB charging into the picture as well, it's not terrible. Well chuffed with it so far.
