Resistance, such as a light bulb, has a power factor of 1.

Yes and no. I just measured an incandescent bulb with my Kill-a-Watt and it displayed a PF of 0.99 to 1.00

Hi Resistance loads are a pf of 1. If the KAW (which are quite nice) reads .99 it is a measurement error.
I never said it read .99, I said the display cycled slightly between 0.99 and 1.00, typical of any consumer level measuring device with a digital display.
led's are NOT a resistance load.
Exactly my point - these days not all light bulbs are incandescent and therefore not a "resistance load" as you suggested. :W
