An analysis of compact fluorescent lamps (CFL) was conducted to determine their advantages, disadvantages, and the economic value of using them over incandescent lighting. Energy demands are increasing every year; increased use of compact fluorescent lamps may reduce the need to build new power plants. Compact fluorescent lamps last longer and consume less energy than incandescent lamps; they save consumers money over the long run and can be used in regular, wired-in luminaries. No comprehensive analysis exists discussing the economic benefits and side-effects behind switching from incandescent lamps to CFLs.

Findings

Use a 23 W electronic CFL to replace a 100 W general lighting service lamp, not a 20W lamp.

Use a 20 W electronic CFL to replace a 75 W incandescent lamp.

Compare and contrast the initial cost and potential energy consumption of compact fluorescent and general lighting lamps when designing a residence.

Use compact fluorescent lamps in commercial buildings to reduce lighting costs.

Reduce harmonic voltages by either installing distributed filters or by improving the quality of electronic control gear.


Key Concepts

Over its lifespan, the energy cost of a 23 W electronic CFL is at least 2.5 times less than that of a 100 W incandescent lamp.

Though more expensive to setup, within six years, both residential and commercial customers recover and save money by using electronic CFLs instead of incandescent lamps.

Results showed that the types of lamps recommended by CFL manufacturers as equal replacements for incandescent lamps were incorrect.

Compact fluorescent lamps have higher wattages and smaller relative luminous flux reduction than incandescent lamps.
