I have a director who would like three moveable fixtures on deck. Something like an ETC S4 ellipsoidal on a rolling spotlight base, with the fixture at chest height. My job is power. I have a few inverter/battery setups in mind, but can anyone answer the following? - What amperage for a ETC S4 Ellips. running at full? (ETC's site is not helping.) - Does the Shakespeare actually run on DC as well as AC, as their spec sheet tells me? Meaning, could I rent Shakespeares and skip the inverter? Or am I missing something? I am concerned about cost. The higher the amperage, the more these parts are going to cost me. Does anyone have a suggestion for a fixture that looks pretty good at around 65% and has a relatively low amerage requirement?
