What lights for Randonneuring?

I signed up for a series of randonneuring events this summer. The long rides are not until June but I want to be prepared.

We'll be riding on dark country roads so I need a front light that will last 8 hours on a charge and light up the road in front of me.

I was offered a Cygo-Lite 850 by a friend. Is this adequate or do I have to go to a $500 solution like a Light and Motion Seca 2500? I know the ultimate solution is a hub generator but I'm not sure I'm ready for that kind of investment.

Anyone do any long distance night riding?

I used a Cygolite 680 for most of my randonneuring, including Paris-Brest Paris. Sounds like the 850 is even better.

The thing to keep in mind is that the battery will only last an hour or so if the light is on full brightness. So I typically ran mine on the lowest setting to make sure it wouldn't run out of juice at the wrong time.

Whole sub forum here: https://www.bikeforums.net/long-dist...rance-cycling/



Hub dynamos never run out of amp hours, and the competition amongst companies making LED lights for them in recent years

has resulted in bright lights being made..

shimano dyno-hub wheel pre built, dont cost much

and the German Busch and Muller firm makes a wide variety of Head and Tail lights ..


Addition, getting a Planet Bike (US brand, UK different name) dynamo handle bar light, It comes Off the bars ,
like a battery light unplugging the wire to the hub.. with summer coming It wont be needed much..

My daily ride in the winter rain has been Schmidt disc hub, their eDelux LED light, +a wired tail light..


I think Paris-Brest Paris Requires Dynamo powered lights .. maybe add a battery light for fast nighttime downhills..

It does not. All that they require is that you have working lights of some kind.

If you go with a USB rechargeable, get more light than you think you need and run it on lower power. The size and weight are about the same and the light will last longer between charges.

Also, check to see whether the light can run and charge simultaneously from an external USB or other battery pack. Some can, some can't.

I have the Light and Motion Urban 500 and hardly ever need it on full power, so I'll run it on medium when riding solo or low in a group. Occasionally I'll run it on high for a few minutes on some tricky rural roads where I know deer crossings are likely. On medium or low it'll usually last the duration of my long solo rides or group rides. If I plan to be out longer than 2-3 hours I carry a spare USB battery for recharging just in case.

But that only catch to the Urban 500 is it cannot be charged and run simultaneously. One or the other. It's my only USB rechargeable device -- including lights, phones, video camera -- that cannot be charged and run simultaneously. Odd quirk but only L&M know why it's designed that way. Even my $15 generic Chinese helmet light can run and charge simultaneously off a tiny outboard USB battery if needed.

But the L&M Urban 1000 or Taz lights would last even longer with plenty of light for most situations.

I'm also impressed with the new Serfas E-Lume beam pattern via a local shop display. And the E-Lume prices have dropped significantly so they're excellent values now.

I'm not sure the beam pattern is as different now among the better lights. I've compared several different brands and models -- Cygolite, Serfas, L&M, Niterider, etc. -- via REI's display and they're all pretty similar. Only my older Serfas SL-255, which runs on a pair of ordinary AA batteries, is significantly different -- it has more of a spot beam. I like it for the MUP at night because it's less likely to blind oncoming cyclists and pedestrians. I made a hood for the L&M Urban 500 for the same purpose.

My Shimano DH3D32 hub cost me $45 plus shipping. I've run it almost 12,000 miles and have never lifted a finger to maintain it. It's getting a touch sloppy, so I'm gonna retire it pretty soon, but I'd call that a pretty good value. I'm not trying to pile on with the dyno chatter, but merely state this to suggest dyno options don't have to be expensive.

Thanks for all the responses. I overlooked the Long Distance forum. I will direct future questions there.

I will take my friend up on this Cygolite for now and consider a hub for later. The cheapest dynamo hub I can find in my area is $140.00.

The B&M Ixon IQ Premium is my favorite brevet light because it runs on rechargeable AA batteries so you never run out of power. I use AA powered B&M tail lights for the same reason.

If I was gonna ride much in the dark, and/or do long rando rides in darkness, I would just get a dyno hub setup. It will leave you with one less thing to worry about. (Battery life.)

A lot of people seem very impressed with the SP hubs - low prices, high output and quality.

I'd recommend completing a series with battery lights first to make sure you like it before spending the money on a dynamo setup.
