They give a white-looking light that should cover the absorbtion spectrum
of chlorophyll and accessory light-absorbing pigments well. I am thinking
of doing the same thing as you, Cliff. One advantage of such a setup that
I see is that if I want to reduce the light level (which is the only way I
know to control a green water outbreak), all I have to do is unscrew the
big multi-tube lights and put in only one 8-watt single tube unit. That
way I can reduce the light and reduce electricity consumption. The other
alternative is to keep all the lights on and paper over the top of the tank
to cut out a lot of the light.
