DX SKU5937 does the trick. I put one together with their 800mA driver and Cree Q5 emitter and it throws really well. As we all know that a smooth reflector will throw better than a textured one.

It's not a huge difference over the usual textured reflectors and the beam is not as pretty, but is the only way to go if you want the absolute amount of throw out of a reflectored P60LED module. Maybe someone will come out with an aspheric P60 dropin, but somehow I doubt it...
