I've had a run of keychain lights lately. And today I have another one by MecArmy. I recently reviewed the SGN7, and today it's the SGN3, a much smaller keychain light. This one has three emitters (white, red, and uv).
Seems that I've been on a keychain light kick lately, and here's another one! Well, in some sense, anyway. This is more of a rectangular light with unusual features.... Also my first MecArmy light in basically forever (the other being the PT16, which I really liked.) Read on for more info and thoughts about this MecArmy SGN7!
