Sadly, age and genes make me one of those cyclists who needs 1,000 or more lumens to see at night--if I'm using an American-style or Chinese-style light that simply scatters those lumens randomly about the landscape. I've owned a few of those.
Out of curiosity, what light are you using now that works for seeing down the road with a lot of light?
While my Edelux II is good enough for most situations, it hasn't been ideal for everything.
For the 10-20% of my riding with really bad lighting (a mix of curvy trail with bright streetlights and completely dark areas), the best light I've found so far is the Light and Motion Taz. It's bright enough to light up the road like daylight and the color of light it puts out is really excellent on the eyes - but it doesn't have as much throw as I would ideally like.
The best like I've found for throw is the Phillips Saferide. It's also very good for the color and light out put it puts out. It's not as good on corners though.
Neither light has the runtime I would prefer - 1.5 hours on high for both.
I haven't been able to find anything that has good color output, a lot of throw down the road, as bright on the road as daylight, and doesn't blind people (by blind I don't mean annoy, I mean so bright people clear out in front of me and curse at me and look like they want to throw something at me - the result of a wide beam mountain bike light). The Phillips Saferide is the best compromise I've found so far for the worst lighting conditions. What have you found that works well for you?
