All I can say is WOW! I know it's been said a thousand times before but it really is incredible how such a small light can be so bright. The quality is also top notch, light years ahead of the Mag Solitaires I carried years ago. I'm so glad I found this fine forum or I may never have learned that such a light existed. The problem now is that I'm hooked on ARC lights and will have to get more.
