Elsewhere in this forum is a thread titled "How many lumens to see at night" or something similar. The answer: ~850L. That's two MagicShines... whoa. Yet, I agree! I don't doubt that there are people who find 200 or even 100 lumens more than enough, but as someone already said in this thread: a lot depends on what you are actually working with as per eyes. Mine need every single lumen of the single MagicShine I am running and I already have a 'Y' connector in anticipation of running a second lighthead in the near future. If that isn't you, rejoice! But know that you are the exception. Most people could use more light at nigh not less. Most people riding at night in Europe where the Busch and Mueller lights were developed don't have the kind of rural infrastructure that exists in large parts of the U.S. I ride between two cities and the unincorporated area between them has no lighting infrastructure whatsoever. I've done the "smack the hidden object in the road and wreck your tandem and crack your brand new NightRider Classic (110 lumens)" because you think you can see. I wonder how many of the 1 watt advocates are that way because they have never experienced more?
