I picked up the Terralux kit for an old AAA MiniMag. I quite like it.
The light has a bit of a greenish yellow tinge to it, but it's not noticeably annoying when used by itself. The reviews said there would be a distracting bluish centre and a lot of ringiness, but I don't see any evidence of either.
Granted, it's not a L2D-CE (just got mine). But it puts out an entirely useful beam of light, and it's near weightless in a coat pocket.
