| Load and use | kWh formula result | Example at $0.30/kWh | Boundary |
|---|---|---|---|
| 5 W for 3 h/day | 5.5 kWh/year | $1.64/year | Low-use room example; replace the tariff and hours before comparing projects. |
| 7 W for 5 h/day | 12.8 kWh/year | $3.83/year | Typical evening-use check; annual kWh = watts / 1,000 x hours/day x 365. |
| 10 W for 8 h/day | 29.2 kWh/year | $8.76/year | Multiply by fitting count when the whole room or zone operates together. |
| 15 W for 10 h/day | 54.8 kWh/year | $16.43/year | Long-hour groups need the lighting output and control state beside the energy note. |
| 30 W for 12 h/day | 131.4 kWh/year | $39.42/year | High-load or long-run example; no tariff, rebate or payback claim is made here. |
