Why In The USA Energy Star didn't mention CFL lights has Power Factoring?

Shhh! Don't tell the power companies. They will change their meters to correctly measure the power we are actually using raising our electric bills.

If "cap and trade" becomes the law of the land, according to Obama we won't be able to afford electricity anyway!

Most of the modern CFL's use power transistors to produce the frequencies needed to excite the plasma hence they are not necessarily an inductive load but could easily be a capacitive load as they are essentially switched power supplies that rectify the AC to DC before inverting it to the appropriate frequencies.

You can't really compare the power factors in the traditional sense as it won't be a linear load and could easily be measured as a poor inductive load by those kill-a-watt type meters when in fact they are not.

Chances are they are as cheap as they can be so whatever they are doing to the AC grid is probably not nice but could average out over a neighborhood as they would occur due to commutation spikes on a beat frequency between the AC supply frequency and the actual frequencies used to excite the plasma, since the plasma excitation power is on it's own oscillator, their effects would not be synchronized from CFL to CFL thereby allowing the apparent poor inductive reactance to average out.

Basically, they don't mention it because you can't measure the power factor in the traditional sense but that doesn't stop people from trying whenever they buy a meter with a nifty PF setting.

Actually dude, let me explain what the difference between the CFL and your regular old incandescent bulb.

Take your regular, old, incandescent light bulb. . Out of the amount of electricity it uses, only about 5% of the output is actual light. The other 95% would be heat, which is why it's gets hot. This means it's far more efficient for heating than lighting... but no one uses it for heat.

Now we have the new CFL light bulbs, with significantly higher lifetime and uses 20% for light compared to the 5% the incandescent light bulb uses. So, if order to output the same amount of light, you'd only need 15 watts to balance the 60 watt incandescent bulb. So yes, they use 25% of the power that incandescent light bulbs use, or 1/4.

I didn't understand 1/2 of what you said. I work at a utility exploration center and we hook light bulbs up to watt meters. I can tell you that a 60 watt bulb uses 60 watts and for the same amount of light you can use a 15 watt CFL which uses 15 watts. That is how my electricity is measured and billed so how can that mean it uses a different amount of energy?

Assuming this is true of CFL's, it sounds like they will still use 1/2 the energy for the same amount of light.

Also, on the same circuit as capacitive loads, such as switching power supplies (computers, TV's, DVD players, etc.) the power factors should cancel out, shouldn't they?

How many morons in the USA who went to public school have a clue what you are talking about?

Our president thinks putting air in your tires will have the effect on the oil market as producing billions of barrels of oil.
