Any chance of some photos of your set ups Baal? Good to see how it looks for ideas.

Dark this morning and dark tonight.
The light has a bluer hue to it than the the saferide. The beam shape is a bit different with a more sharply delineated horizontal cut off at the top of the beam. There is a brighter wedge of light in the middle and toward the front of the projection on the ground. It was wet this morning and I rode through some fog at the top of one tree hill. The brighter part of the light could be seen as a narrow spreading triangle through the fog.
The light gets washed out a bit by streetlights and oncoming cars. Where there is no traffic or streetlights it is quite adequate.
TBH though I am surprised by just how much better the saferide is on high. The saferide has a broader beam pattern without any hot spots and just puts out considerably more light. I was a bit surprised at the difference given the saferide is 80 lux and the luxos u is 70/90 lux. Even on the 90 setting it doesn't come close. If I put the saferide on high at the same time it's more yellow light just appeared to wash the luxos u away.
I would rate the luxos as somewhere between the saferide on low and high and probably a bit closer to low, this is OK though as I ended up riding on low with the saferide most of the time, given its limited run time on high. So most of the time I have a more light now.
I'll keep the saferide on there and use it on high for the fast roo riddled downhill bits of the commute.

The secula plus on the back is fantastic. I appear to be getting a wider berth in general with this running and it puts out a nice red glow. Where I have it placed on the drive side seat stay it has the added benefit of letting me see which gear I'm in as it shines a glow on the cassette. :)

Been sh1tty weather here lately so the luxos has had a good test in the rain. No problems whatsoever :)
The handlebar switch of the u is sup[er handy and having used it I wouldn't consider the b with it's absence of one.
I've found the luxos will stay on the 90 lux setting for the entire commute if I'm not stopped at the lights or miss them. Not sure if that's usual, but the elcheapo shimano dynohub obviously has the goods.
It's a great security having a dyno light front and rear that is always on and has no need for monitoring charge. Highly recommended for commuting :!:

Does the beam shape of the Luxos U vary with bike speed (i.e. a longer throw when cycling faster)?

In layman's terms...
At lower crawling speeds the light throws more to the near field.
When you pick up speed it will engage more into the distance.
When you switch on flood mode even more will be thrown into the distance.

Tbh I don't notice any change at low speed. How slow do you have to be going?

Biker I don't really notice the beam vary with speed but I don't get below 15 ish kph. The flood setting does make the light a bit brighter and throw further.

My masi is off the road for the moment. Needs new brake pads and I'm going to replace all the cables as well. When that done I'll post up some photos of the install.

CX bike so I have the brake & gear cables on top of the top tube. The wire then heads and is zip tied to my rear rack and then to the light

To the front it runs under a Relevate Gas Tank bag and to the front light.

Nice neat solution with the spiral wrap. I like it. :)

what the hell are you powering? 15amp!

If this is for a taillight, walk into jaycar and get the lightest gauge speaker / twin core cable they have. Take your existing cable to match.

eg

If you want to be fancy, try to find some 'mic' wire / miniature coax, it's easier to run internally.

Maybe you missed the bit were I said I'm an electrical spaz, I throw my hands up, I just solder wires together and hope they work :) I just don't want it to melt or anything.
Hub is 2.4w/6v, EYC up front and Secula on the rear.

very simplistic:
P = VI , watts = volts x amps

At a nominal 6v / 2.4W: 2.4 = 6xI, I = 2.4/6 = 0.4A.
