T5 lighting

[Reefer Rob]

One thing you will get with T5s is a very even distibution of light, since the whole top of your tank is covered with tubes. Very little shadowing in the tank, and the corals receive light on all sides, more similar to what would happen in nature. To duplicate this with a single point light you would need to move it across the top of the tank during the course of the day to simulate the movement of the sun.
