I'm no professor, but Ross' advice is good. You might be able grow and flower some plants under light from only one end of the spectrum or the other. You might find that certain species thrive better in one over the other. You might be able to put on new growth under a UV blacklight, as did Daemos. You might be able to flower orchids under a traffic light! If a light photon is a light photon, there shouldn't be any difference as long as the lumen output is there. You don't see too many people using cool white fluorescents, or for that matter traffic lights to grow plants, do you?
Your best bet is 5000K or "full spectrum." This will provide a variety of "color" or wavelengths needed for all of your plants to grow and bloom.
