If this is a drop ceiling I would probably go with 4 three bulb T-8 troffers. These are more efficent than the old T-12 bulbs while providing the same amount of light. There is also a T-8 troffer on the market where one bulb will light when the power is down as an alternative to the wall pack emergency lights.
