1.4.4 Reduce the number of lamps

1.4.4 Reduce the number of lamps

Description

The measure proposes to remove from each fixture a certain number of lamps depending on the light levels previously measured with a light meter. Lamps will be removed where light levels are higher than the acceptable working levels.

Benefits

  • The reduced number of lamps reduces also the energy consumption

  • Improve visual comfort

  • Less maintenance will be required

Limitations

  • De-lamping may require some minimal wiring changes or the installation of phantom tubes

  • A preliminary daylight study may be necessary

Economic assessment

Initial investment: low. The cost is zero if the measure is self-made installed. Other costs may appear if wiring should be changed or if a maintenance company is contracted.
