To be honest, I cannot think of anything that a flashlight would prove with a scope and an analogue light meter. In any case, barring any more concrete information about this test, I should not make any judgement or presuppose what it might have been. I am, though, still curious about this test and would appreciate any pictures if you have them of the entire test that was carried out.
