2.4.4 Replacement of incandescent lamps by Compact Fluorescent Lamps (CFLs)

2.4.4 Replacement of incandescent lamps by Compact Fluorescent Lamps (CFLs)

Description

In a CFL, an electric current is driven through a tube containing argon and a small amount of mercury vapor. This generates invisible ultraviolet light that excites a fluorescent coating (called phosphor) on the inside of the tube, which then emits visible light.

Benefits

  • CFLs use a more efficient technology reaching the same levels of light with a power up to a 80% lower than incandescent lamps
  • Lifespan 15% more than incandescent lamps
  • CFLs can directly replace incandescent lamps since they carry integrated auxiliary equipment

Limitations

  • Turning them on and off too frequently can reduce their lifetime
  • They are meant only for ambient light
  • Presence of mercury in CFLs
  • A regular CFL is not meant to be used with a dimmer switch as it may burn out quickly. The same applies to use CFLs with timers

Economic assessment

Initial investment: low, around 5-7 euros/unit.
Payback: low, less than one year.
Lower maintenance costs than incandescent ones.
