That looks nice. Low power but nice. At 20 lumen it's not going to garner a lot of attention during the day but at night it shouldn't be half bad. Xeccon also sent me one of their little "self contained" mini rear lamps ( Geinea III ) for review. Not real bright but certainly enough to be well seen at night. They don't say how bright it is but 20-30 lumen is about right. Of course I have brighter lamps so I've never really used the ones with small outputs.
