It gives me no pleasure however it is scientific to correct incorrect science when it is posted and this is a part of the process of open scientific discussion. The wave particle duality of photons is dependent upon the energy of the photons and the time and length scales of measurement - there is no link to the power output of the light source which is merely a means to make the interference pattern more visible under classroom conditions. Said interference pattern being due to the wave type interaction you have now said is absent.
I presume to tell you that you are mistaken as I have a PhD in theoretical physics and my training and subsequent career in research has made me well qualified in this area - no offence but you are completely wrong no matter that you are unable to accept it. I would be happy to point you in the direction of the relevent texts if you are sufficiently motivated.
Cable phoolery exists because pseudo science is used to justify it so my response is entirely appropriate.
