Wooly undies (&lamp set) in Aldi - must be autumn

[irc]

Not so good. There is a big difference in brightness from the area below the cutoff 15 or 20 ft ahead of the bike and the area immediately ahead of the bike. I will need to try it on an unlit path to see how it works actually riding.

Generally that's how you WANT a shaped-beam to work. Of course it can be too extreme ...

Why? After all in daylight you don't want the road or ground 6 feet in front to be harder to see than the road/ground 20 feet away?

I would have thought an ideal beam would be equally bright with a clean cutoff to avoid dazzling drivers.

You're nearer to it [the road 6' in front], so you don't need as much light. And
You've already seen it, cos it was well illuminated a second earlier, and
When you're worried about the nearest 6' you're usually going slower, so less danger

If I am going slower it may be because these is a hazard. Narrow gate etc. I want to see that as much as something further away. Maybe just personal preference or as suggested the degree. As a rough idea I perceive the far away part of the beam to be around 3 or 4x brighter than the near part.

Have you got an Aldi light? Because if you haven't there is no point telling me the beam is OK as your beam on your light may be perfectly acceptable while mine isn't.

I was only commenting on what you said "an ideal beam would be"
If i had this light, I hope I'd have made that clear!
