Need Help with LED lights.

[bgruchow]

I currently am using coralife lighting. I love the look that the LED lights give but do not fully understand them. I would only like to add some to go with my Coralife light. I really like the shimmer effect that it gives and I also want some night led. My guess is that they need a seperate power supply? Also what ones are gone to give me shimmer effect and what ones can I use as a night LED. If I sound new it is because I am. I have been a freshwater fan for years and for the last 7 months have gotten involved in saltwater.
