Re: Reflector measurements (long)
Ivo's results are interesting and useful. However, he is
dismissing/discounting the reults with a "diffuse" reflector. The test was
set up with a "Target" to be hit by the reflector. If you are using a
pendant lighting system sitting a distance above the tank, this is the type
of information you want. If, like most of us, you have a strip light sitting
directly over the water, then a diffuse reflector is not so bad. Everything
that bounces off the reflector still enters the tank and most of it is
available to whatever plant can find a location within its path.
Now if Ivo were to repeat this experiment by measuring the light coming off a
piece of white paper underneath a tank full of water with the light sitting
directly on top of the tank, then he would have something more relevant.
