A few Actinic facts:
"Actinic" is a common name coined by Phillips lighting to refer to a bulb that produce light with a wavelength of 420nm. It was originally used by the scanner in a copy machine. Reef hobbiests refer to anything around the 400-480nm wavelength.
Although 420 is still in the visible range it is not easily detected by the human eye and appears very dim to us.
It causes flourescing proteins to glow.
Of all the visible light wavelengths it penetrates furthest into water. This is the reason that deep clear water looks dark blue.
Of the two photosynthetic peaks, actinic light lands very near the center of the peak at the blue end at 440nm.
A 100% actinic lighting scheme will work (I've done it) but you'll need a bit more watts that normal because actinic bulbs seem to have a little less PAR that dayligh bulbs. Animals that don't flouresce will appear almost black but animals that flouresce will appear very bright.

another thing you could do is get 14k bulbs ........ the lower the kelvin rating the more coral growth you will gett , the higher the kelvin rating the more its gfoing to help with your colour , so generally if you want corals to grow (like frags) go with 10k but if they are allready at the size you want them go with a higher kelvin rating
