The amount of fixtures you will need depends on the space you are trying to illuminate. At a mounting height of 15' the light distribution is 60' x 60'.
We also have a Lighting Layout Tool (http://www.e-conolight.com/lightinglayout) that you can use to help you decide the right amount of fixtures for your application space. If you have further questions please contact 888-243-9445 to speak with an applications engineer about your specific application.
