Can I use hydro lights for a marine tank setup?

Question

i need to use Metal Halides for the marine tank. I'm not quite sure what Metal Halides is but I did read a for sale advert selling Hydroponic Metal Halides. As the lighting for Marine Tank setups are very expensive I'm trying to find out if Hydro lighting is going to be cheaper and just as effective to keep the coral alive.

These pages will tell you of the output necessary for your tank. All on-line stores will carry them and ship them to you. Considering the total cost of setting up a marine tank, I would suggest using the correct lighting form the beginning.
