2.4.2 Installation of electronic ballast

Description

Electrical ballast is a device whose aim is limiting the amount of current that passes through a discharge lamp during the start-up. First, they provide the necessary voltage to start up the lamp and after that they limit the current. Lamps that use ballast are halogen lamps, fluorescent lamps and High Intensity Discharge lamps (HID).

Benefits

  • A reduction in the energy consumption of 16% can be reached
  • With dimmable electronic ballasts, the intensity of light can be controlled and adjusted reaching an additional reduction in the energy consumption up to 70%
  • The typical flickering and the stroboscopic effect disappear because of their high frequency
  • Extend the lifetime of the lamps
  • Noiseless
  • One electronic ballast can substitute more than one magnetic ballast

Limitations

  • Electronic ballasts have shorter lifetime than electromagnetic ones
  • Non-recyclable

Economic assessment

Initial investment: medium. Around 30 euros/unit.
Payback: medium. More than 5 years.
