Vinh did a nice job on the boost & tint. I am still experimenting with various methods of identifying the "off" location so I can preselect what level I want before I turn it on(by far the biggest complaint I have heard regarding this light). I used GITD paint with a small dot on both ring & body, then I used a silicone "bump" so in the dark I could tell where "0" was...I am reluctant to give up as I like the light, size, shape output etc, but I sure wish I knew what the Sunwayman design team had in mind when they created the light. As you can tell by sheer quantity alone, I really like the magnetic control ring UI, and although my redundancy may seem excessive to some, other than the Mirages, each light is different from the others in some way shape or form...
