How to Use This Calculator
- Enter the Number of Lights you plan to use on set.
- Input Wattage per Light (W) — check the fixture spec sheet for accurate values.
- Set Voltage (V) — North America is typically 120 V; studio outlets may be 208 V or 240 V.
- Total Wattage (W) and Total Amps (A) tell you the combined electrical load.
- Circuits Needed shows how many 20-amp circuits to reserve so you do not trip breakers.
- Energy per Day (kWh) and Heat Output (BTU/hr) help with budget and HVAC planning.
