The 4Sevens Quark 123, R5 Edition has a moonlight output of 0.2 lumens out-the-front which IMO is an ideal low end output. 3 lumen is way brighter than moonlight, OTOH 0.04 lumen is more like starlight -- extremely dim. The Quark 123 is a very good light IMO -- not as small as 1xAAA, but small enough for pocket carry.
