Which one's that? I tried a Solidlights which was comparable to my
nominally 10W halogen at half charge (the halogen is unregulated),
but it wouldn't last a week's commute if I was doing the whole
16 miles each way at all. (It would probably last if I was doing my
usual trip just from the Park and Ride, but then it's all streetlit
and a Cateye EL300 is fine. (I cut the dynamo mounting tab off my folder
as part of changing it's wheel size. I did try an old SA dynohub for a
while, but it's a bit feeble compared with a modern dynamo and I didn't
have the optimal bulb and even when it was turned off the gears felt
draggier than the other hub. The bike I do the longer journey on has
a bottle dynamo, which was very unreliable when new, but rewiring it
with something other than knotted extruded cheese to just do the front
bulb and use an earth wire fixed that.)
