low energy bulbs can increase heating bill ?

I do not understand what you are trying to say. Power is watts. "45 volt/amps" the bulb uses 230v not 45v.
In simple terms Volts x Amps = Watts.
So an appliance supplied with 230volts and drawing 1 amp would be rated at 230 watts.
You could express this as 230volt/amps for some electrical circuits.
However to supply Alternating Currents circuits volt/amps can be higher than watts.0 -
I think the bottom line here is that an energy saver will produce the same amount of light as a normal bulb but will use less real power. i.e. it's more efficient at generating light. It will still waste some energy as heat, but nowhere near as much as a standard bulb
I think power factor and apparent power is best left to the 'leccy engineers amongst us
Out of interest I would imagine that CFLs have been designed with a unity power factoror would the cynics disagree?

I take it that's to generate some heatI guess the light is a bonus

Turns out CFLs aren't that well designed for power factor
but even so they should still be more efficient for providing light - after all the supply network has put up with normal bulb usage until now...

a good article, you wouldn't want to switch a CFL on and off too often after reading that0
