I fully agree. Making the light go where you want it is an entirely different question than 'restrike'. Just guessing, I would think that only 10-20% of the light would go into the tank (on a typical set up) if you do not use a reflector.
My question was meant to stimulate discussion of 'restrike'. By reading various forums I got the opinion that some people think that the energy 'restriking' the lamp is sucked into a black hole or something.
