&quot;Power factor is always a number between zero and one because the watts&nbsp; drawn by a device are always less than or equal to the volt-amperes&quot;


As for the light bulbs (produced in different technologies), it is always the best thing to rely on their &quot;candela&quot; or &quot;lumen&quot; figures, since they express the real light power (quantity of photons, so to speak) that is emitted by the bulb at certain ''color temperature&quot; (in the degrees of Kelvin) and are not affected&nbsp; by the temperature (heat) losses.
