Thanks for the excellent suggestion.

34.2W bulb only (60 watt soft white incandescent)

755W heater only

811W heater plus bulb

811-755 = 56W

Power Factor was 1.00 for all readings above.

So in theory they should all match their wattage ratings within the expected tolerance of a high volume mass produced item at low price point.
Spec accuracy is listed as 0.2%

I think I may have a defective unit.
