Actinic white, what is it?
"Actinic White" is also referred to as a 50/50 lamp, which helps make more sense of what it actually is.
It's a lamp that has 50% actinic phosphors, and 50% Daylight phosphors, so in effect you get a lamp that produces both full spectrum daylight and the lower actinic spectrum.
These lamps tend to be much dimmer than a true Aquasun, and have a "pink" appearance. Most recommend using a pure one of each (1 Aquasun, 1 Super Actinic) for the best effect.
In my case I use 2 Daylight and 2 Super Actinic for excellent spectrum coverage, intensity and white-blue appearance. If I used all Actinic White tubes the tank would look very pink and not be as brightly lit.
