Five of the nine current meters showed a value in the (repeatable) experiments that was well above the actual power consumption. It was up to 582 per cent higher for certain trials. Two counters showed a 30 percent lower value. The greatest differences were when dimmers were connected in combination with power saving and LED lamps.
