I carry a Surefire E2D Defender LED. It almost fits your requirements.
It is two stage, 10 lumen low, 200 lumen high. When you hit the tail cap button , you get the high beam first. A second press gets you the low beam. Has sturdy pocket clip, but its not oriented the way you want it (bezel up).
Its a good sturdy light. I prefer the two stage lights as long as the first stage is the high beam. I like having the low intensity 2nd stage to use as a work light when i dont need to be blinded the 200 lumens.
