ATI 48" Power Module 3x75W LED And 4x54W T5 ATI 48" Purple Plus T5 Bulb - 54W Radium 400watt SE 20000K Bulb
The ATI Power module is a hybrid lighting system that combines high-end T5 lighting with LED's for the greatest flexibility in color, intensity, and spectrum.  This is a no-compromise fixture for reef aquarists looking to build the ultimate system.  The build quality of this fixture truly is a cut above.  It is heavy and substantial.  In addition to the material quality, the design is well thought out and intuitive.  For example, there is only one cord exiting from the unit to the controller, which is remarkable for a fixture with the number of independently controllable lights as the ATI Power module has. Purple Plus
As the name might indicate, the ATI Purple Plus gives off a very purple light. This color is achieved by blending the red and blue wavelengths. There is very little actual violet light in this bulb as its spectral output drops off sharply as it approaches 400nm. If you like the purple aesthetic this bulb gives you that more than any other that ATI makes.
The German-made Radium 20,000K bulb is a legend in the reefkeeping hobby.  You will not have to look very hard to find a legion of reef aquarists that swear by this bulb.  For decades this bulb illuminated some of the most incredible show tanks in the world.  This metal halide bulb is the perfect blend of intensity and aesthetics with a long track record of promoting coral growth and color.

True Actinic
The ATI True Actinic has a very unique spectral profile compared to the other offerings by ATI. The True Actinic possesses an enormous curve that peaks at around 430nm. The human eye does not see this spectrum of light very well, so this bulb looks visibly dim compared to the others.
