The "K" rating is the color of the light, not the lumen output......
you want 6500K "Daylight" color lights....they are more white/blue than the standard yellow/red.....
The lumens are not really as important as the right color specturm.....

No, the color temperature (3000K) isn't multiplied by the number of bulbs to get the number of lumens.
Yes, that would be bright enough, but the common consensus is that you want 6500K light, which is a color very similar to the sun. I haven't seen any real studies that have shown that to be the optimum, but I've grown many fruits with 6500K CFL grow bulbs and I can testify that they work well.

good to hear lol! your lights will work ok but it would be easy enough to get a desk lamp and regular lightbulb in the right k range.

Look harder. The Kelvin range of the bulb will always be posted on the label.
