I just noticed on the previous page your discussion about the difference between led light source and t5 or mh and I'm not sure I understand what you mean or maybe I don't really agree with it..
Maybe when t5 are concerned since they produce light along the entire length of the bulb thus spreading out the light source more than a point source like a mh or led, but I wouldn't see any difference between an led strip that is as long as a t5 bulb or even a light like a Radion pro or a Mitras which has multiple light sources (granted, in a smaller area than a strip light) but light still bounces around a tank and reflects in all sorts of angles doesn't it?
I know that the strongest light is coming from a direct line from the source.. This is the case for mh or led, why would there be a reduction of light deeper in the coral from an led than from a mh?
I don't really understand, I guess..
