What exactly quantifies "strong lighting"?

That comes out to around 4.7w per gallon on your tank. That would be
considered very adquate lighting for most corals, unless you are going to do
stoneys or clams. Then you would want 5+w per gallon.

I was wondering what the limit is for me on growing corals and maybe an
anemone or two. I have purchased a PC from Coralife Aqualight 260
atts -
2x Actinic and 2x 10,000K lights. This lighting setup is for a 55 gallon
aquarium. Thanks in advance for all your input folks.
