karlseith said:What type of tank will it be? Fish only, reef?
For a fish only you will need minimal lighting. A standard florescent strip light will do the trick. You may want to look into different bulb types to help bring out the colors of the fish.
If your planning on adding light dependent inhabitants corals/anemones/clams etc... you will need substantially more light, and to provide us more details for a better suggestion. HTH's
