What light requirements need for tomatoes to ripen?

[furniture@finewoodstudio.]

For my two tomato plants I have cfl 2800K 125W, 6500K 200W, 5000K 200W and they are gowing and producing fruit like crazy. But my question is whta light requirement is needed to ripen the fruit? I read an ad for hps lighting the said that you need 10,000K to ripen the fruit, is that true? In the grow room the plants receive about 12000lx. During the warmer days here in the Pacific NW I have the plants on a dolly and I can move them outside. But it is so cold this year that I cannot leave them outside. It has been 5-15 degrees below normal.
