Live rock doesn't require any true lighting and a flurecent light or basic marine light will do. However some live rock can come with small organisms that need light to survive (unsure on that though-someone might be able to expand on that). Although I haven't ever seen any live rock that has a neccesity of high spectrum light. In short, it's not required, but will be fine with it as well. At least a basic light for live rock is recommended. I just use a flurecent lamp light and it does well.
