They should, IMVAIO, at least state the type of night cycling that the
light is appropriate for. There should be some sort of a standards
association that comes up with a rating system, i.e.
W-Suitable for well-lit roads at speeds up to 10 mph
M-Suitable for unlit roads at speeds up to 15 mph
S-Suitable for unlit roads at speeds up to 25 mph
O-Suitable for unlit off-road trails
You were going down a hill at 20 mph, in an area that apparently had no
street lights, with light that did almost nothing in terms of
illuminating the roads. You had a "be legal" light might be appropriate
for slow riding on well lit streets, where there is no need to
illuminate the road far ahead.
Look at the different types of cycling, and the different cycling
infrastructure when choosing a light.
In Amsterdam, where there is a big infrastructure of bicycle paths,
people use low power dynamo headlights and are just fine with them.
In well lit cities and suburbs where I live, a lot of commuters have
bought the Joe Breeze bicycles with hub dynamos and find them adequate
for most of their ride, and supplement them with a good battery powered
light when they have to go through unlit areas, especially on hills.
The area and speed you described would best be served by a high power
LED, halogen, or HID lighting system.
