MAKE THE ESTIMATE WORK HARDER
Use manufacturer specifications or a measured whole-system wattage. We are an independent calculator, not affiliated with a lighting manufacturer.
How we calculate it
Light count × watts per light × power setting × hours ÷ 1,000 × days × rate. Brightness scaling is an approximation; controller standby and power-supply losses are excluded.
Results describe the scenario you enter. They are estimates, not a quote or a guaranteed reduction in your utility bill.
