got my chinee "1800 Lumen Cree XM-L T6" headlamp today. the one thats a clone of the MagicShine MJ800 or whatever. holy CRAP its bright. probably 700 lumens, not 1800, but still. thats just a wild guess, but its nearly as bright as a motorcycle low beam, but somewhat more concentrated into a spot beam. I'll get around to setting up and taking a couple test pictures down a dark road with fixed exposures to compare it with a NR '130 lumen' and a planetbike something, and maybe even my car's lowbeams :) but probably not tonight.
