Sheldon used to have a schematic for wiring your dyno to a rechargeable battery, using a bridge rectifier and a diode. That way, your light stays on when stopped.

Looks like a nice light. I've gone and ordered it as my current comute is in the dark for the next month or so. The cheap light I have now is effective but far too dim.

Poop. I was going to suggest the Cateye Volt 800. Looks that entire line of lights is popular amongst riders in this thread.

It is a great light, I have one of them too.

This was the case about 30 years ago but not with current systems unless you get the really cheap stuff. Almost all dyno systems sold today and for the past 20 or 30 years are 'stand lights' which means they stay on while you're standing still.

We've dyno systems on all of our daily use bikes. Some are hub dyno's and some are bottle dyno's. Lights are B&M, Spanninga, and Schmidt. All work quite well (and we do a lot of riding at night going to/from dinner and grocery).

Two good sources: https://www.dutchbikebits.com/lights and https://www.peterwhitecycles.com/lightingsystems.htm

Be careful about relying on Lumens. A light with low lumens but good optics can be much better than one with 4x as many lumens but poor optics. 100 lumens where you want it is much better than 400 lumens scattered all over. A better measure is Lux which gives you an idea of how much light there is on any surface area, but that's another topic...

Be careful how you aim your lights. Blinding or annoying drivers, other riders, or people walking is a really bad idea.

Fortunately the 'I have to have gobs of flashing lights all over or I'll get killed' bit seems to have died. The overwhelming majority of folks don't flash anymore. Flashing lights are annoying and can cause some drivers to drive in to you instead of seeing you and avoiding you. I think the U.S. is the only developed country that hasn't outlawed them.

Yes, some are way behind the times.

A couple more great sources.

For folks who liked the Phillips Saferide lights, Spanninga has reintroduced them in updated versions called Axendo.

Totally forgot about these. I have one (Phillips) still waiting to be mounted and tried out. Phillips discontinued them and Spanninga picked them up?

CrankyOne and Kickstart ... thanks very much.

I know a lot about bike lights ... because I ride at night a lot.

I admit, though, I haven't done much investigating of dynamo systems because the good ones are expensive, and back when I first started looking ... they all dimmed out depending on vehicle speed. I am glad someone has fixed that, but not surprised ... it seemed pretty obvious.

I will stick with my Light-and-Motions, for most uses. I have a couple bikes where the added weight and complexity of a dynamo hub wouldn't be a drawback. I will check out those links.

Thanks very much.

Yes, Spanninga has the Phillips bike light lineup now.

I recently purchased the Spanninga Elips, which was the Phillips Saferide lumiring tail light. It's available in 3 versions, battery, dyno, and 6v-60v e-bike.
