1.4.3 Cleaning and maintenance of lamps and luminaires regularly


The measure consists in cleaning lamps and luminaires every year with soft moist cotton cloth, soft-bristled anti-static brush, or low-power vacuum cleaner as well as replacing bulb lamp at the end of its lifespan or lenses if they appear yellow.


  • Energy savings in electricity can be up to 50% of electrical consumption in lighting

  • Increase visual comfort of users

  • Avoid light losses due to the inefficiency of lamps and luminaires


  • The energy potential of this measure depends on the previous conditions of the systems

  • In the case of LED luminaires, risk of damage to the LEDs should be considered

  • It is recommended to remove diffusers/covers and reflectors as well as lamps during the cleaning process to clean them separately

Economic assessment

Initial investment: low. The total cost depends on the quantity of luminaires and lamps which must be cleaned and the quantity of bulb lamps which need to be replaced. It reduces costs associated to lighting energy.
