LED bulb
Power: 9 W; example.
A chosen 9 W electrical input; brightness is a separate measurement.
Defined examples — our methodology
The marked power is calibrated. Unmeasured illustration details are representative.
Laptop in use
Power: 50 W; example.
A chosen 50 W electrical draw. Workload affects actual consumption.
