[QUOTE="WayneF, post: 535038, member: 12496"] Right, power factor is an AC efficiency power loss when voltage and current are not in exact phase. It is the inevitable result of the necessary inductance in some circuits. That's just how life is, or at least physics. I don't complain about the power factor, I accept it and understand it. As long as the watts are accurately delivered, then power factor is the power companies problem, not mine. :) My complaint is that some of the larger CFL bulbs use the resulting greater VA number as the marked power rating, but call it watts, which is a false claim. They mark 45 watts when it measures 25 watts, and mark 85 watts when it measures 50 watts. Seemingly intentional fraud. They of course know better. U.S. law requires bulb packaging to show lumens and watts. I wish these did, and I don't know the loopholes. These were bulk packaged imports in plain unmarked boxes, and these did not show or mention lumens, which is omission. And worse, stamped on the bulbs (and in the advertised claims) what they call watts is VA which is a lie, not the honest watts. I don't know how universal the problem. I did check three brands of 13 watt CFL all of which did correctly label the watts accurately (same as they actually measure). But two of two larger ones did not, marked with seriously inflated numbers. The retail packaging labeling was one major difference, present vs. blank. [/QUOTE]
