Coralife PC fixtures?

I have myself a coralife 96w powercompact fish tank light I used to grow corals. The bulb in it is dead so I will have to replace it. My questions is could I use this to grow one single plant? And if so, witch type of spectrum bulb should I go with? 10,000k? Or maybe 6700k?

yeh you could easily, 6700k out of the two spectrums you said.
i'd try and get a hold of a 5000k one for veg, then move to a 2700k
or 3000k for flowering.
good luck
