Lighting energy

Fixtures × watts each = connected kW. kW × hours a day × days a week × 52 = kWh a year. The same for the new fixtures; the difference is the energy the retrofit would save at the same hours.

The figures follow the watts and hours you enter; the actual use depends on how the lights are run.
