Will Compact Florescent Lamps and/or Florescent Fixtures Save the Day?

IT is obvious to say the Compact Florescent replacement lamps (CFLs) can save energy and they will pay for themselves many times over by comparison to powering an incandescent bulb.

I personally use them in my home and office.  I am however not convinced that I am doing the right thing for the power system.

Consider an older home (or office); the electrical system (breakers, transformers, etc.) were engineered for mostly “traditional” linear loads.  An example of a linear load is a resistive load as in incandescent lights, AC Motors and electric heaters.

Today, consumers use so many non-linear devices generally found in consumer electronics: flat screens, computers, television sets, and now the addition of CFL’s.  One may never acknowledge the effects that these devices have on the electrical system.

There is a precious balance of linear and non-linear loads that should be considered.  If a wholesale exchange of bulb (incandescent) to CFL’s were to be considered, there could be a problem with a tipping the balance of non-linear loads.  This can present a problem with overheating the transformer (neutral loading) and or creating unwanted harmonics.

Most devices are designed and built assuming a perfect sinusoidal wave.  The introduction of non-linear loads will corrupt the pure waveform and therefore create a problem down the road.

While I am a user of CFL’s and I promote their usefulness in several applications as a natural solution to reduce energy consumption, I am also keenly aware of the potential problems that overuse may cause.

    Well I know for sure that the energy saving bulbs are at least alot more powerfriendly that the standard “old school” ones. My local council last year to try and encourage a more energy efficient town actually sent every house in the borough 2 free energy saving bulbs to get people going. I used them, and I haven’t looked back since.

  2. Incandescent light bulbs will soon be phased out because they waste a lot of energy.*-:
