Why do corals need fancy lights if the ocean is dark under water?

Because it is not actually dark under water, there is plenty of light (not all spectrums, but does include what is needed) that reaches photosynthetic corals to allow well, photosynthesis to occur.

Corals that live wayyyy further underwater have to be able to utilize lower light levels, or are non-photosynthetic.

Why do corals need fancy lights if the ocean is dark under water?

The sun is very bright and extends to the depths where corals live.

How far does light travel in the ocean?

Sunlight entering the water may travel about 1,000 meters (3,280 feet) into the ocean under the right conditions, but there is rarely any significant light beyond 200 meters (656 feet).

On my home world, we orbit a giant star that lights up the ocean.

I think you can. Some aquaculture farms use greenhouses and sun.
But, sun is somewhat uncontrollable and most corals look pretty brown under all wavelengths.

It also might be too bright for most corals unless you filter the sun.
