Too much to choose from. What is your budget? Are you concerned with heat? what else is in the tank? Your experience and tank age? That's like asking what to add to a pool so you can swim, with out doing any testing or seeing any pictures. Roll the dice and pray would be the same thing.... a guess.
Post a pic of your tank. Pick out some fixtures that you would be willing to buy, in your price range. Post them and ask for opinions, along with the type of anemone you would like to keep. One thing about this hobby, it is NOT a one size fits all. The more info you post, the more accurate and helpful advice you will receive.
