Finnex Fugeray or Current Led plus would be good ones to check into. They offer good light without having the need for co2. They may not grow the highest light plants but will grow the majority just fine. As for your t8 lights, those precede my experience in this hobby. You would probably be able to grow Java fern, anubias, hygrophila, and a few other plants if you wanted to stay with the t8 fixture for now. Growth will be slow but it is possible.
