I'm spec'ing my next randonneuring bike, and I'm looking at lighting options. Maybe this group can help.
I've been doing brevets for about ten years, and have run dynohubs from the start. I know LED lighting has improved since my last build, and I want to consider non-dyno options. The purpose is to save drag, weight, and wiring. I'll typically do a 1200k once a year, so my lighting has to work for that distance.
For reference, my current headlight is a
B&M IQ-X at 100 lux. I find it adequate. I don't power any electronics with my dyno, just lighting.
I think the two things I like most about running dyno are the ability to use lighting without worry about battery life, and the ability to park the bike and go to sleep at an overnight, not fiddle around with charging like I see other randos doing. An example of the former is the worse-case scenario when an all-day rain happens, when I'll run lighting day and night. More typical is lights-on from dusk to dawn, on the first night of an evening start ride. For the latter case, when there are a hundred randos in a gym with a few outlets, charging can be a zoo.
What I don't like about dyno is fiddling with the wiring (particularly after I've traveled somewhere and have to re-assemble the bike), the vulnerability of wires (I have ripped wires out on a crash), and at least the notion that the drag might be costing me real time on a 1200. I said weight, but it's not really that big a deal.
Basically I want brightness for urban, suburban, and pitch black rural, with rain, long running time, and low fuss-factor. As far as budget, under $300.
Suggestions?
