Since you have multiple fixtures, it would be more convenient to set 1 as a Master and others as Slave units. This will allow you to make lighting schedule changes to the Master fixture, which then gets transferred over to the Slave fixtures automatically. Having both fixtures on your network also has its benefits.

You can separately connect to them and individually set their total output percentages; HE or HO and %. You will also be able to adjust the Power Balancing Tech features and select which channels you would like to send more power to.
