ELECTRICITY CALCULATOR
Security floodlight running cost
Estimate electricity used by a security floodlight with your own power, hours and rate.
How this calculation works
Average input watts ÷ 1,000 × hours per day × days gives kWh; multiply by the rate. For motion-activated lights, estimate the actual daily on-time. Fixed fees, taxes and tier changes are excluded.
