Use 10000k. Luis Navarro does and ADG does. They grow plants, they look spectacular, and are easy to get. I am very pleased with my CSL 10000k. I have heard corallife is even better.

10000k looks good. Very similar to the 8800k but slightly bluer. It will be a very crisp white light with a slight blue under tone. Things will look great with it.

69, your nuts. Just pick a light already .

The 10000k can be used by themselves, i am not sure what you mean by this...

10000k: blueish white, some people recomend this light as a sole source while others have complained about it's blarishness. It can be used successfully, however, in combinations with other lights. My major concern is reports that it washes out reds in plants and fishes. And from pics i've seen across the net, i'm thinking those reports might have some truth in them.
