I received my PFO PC retrofit kit and added it to my current lighting, which consists of a 72" Hamilton Lighting retrofit. Three 250W Geisemann 13K SE on electronic ballasts with 2 96W PC... dual actinic 420nm and 460nm.
I added 2 96 watt 460nm 7200K bulbs to give me a total wattage of
1134W. Definitely makes a difference visually... let's see if it does anything to my corals.
BTW... I'm very impressed with the quality of PFO products... the dual ballasts come in a really nice (solid) enclosure with dual switches. The cables are also top notch...

NOTE... This shot is taken at a +1 (EV) Exposure value on my Sony Cybershot. It reflects more closely what you would see if you were looking at the tank in person. Even though my new lighting does make my tank brighter with a more bluish tint, my older shots were actually a little darker than what you would see in person.
