Preventing Light Nuisance


Before installing lighting ask a few simple questions:

  • Is the lighting necessary?
  • Could safety or security be achieved by other measures?
  • Do the lights have to be on all night?

If lighting is necessary, a number of steps should be taken to avoid causing a nuisance:

  • Only use the right amount of light suitable for the task in hand
  • For domestic security lights a 150W lamp is sufficient (High power lamps create too much glare, reducing security and offer poor energy   consumption)
  • For an all-night porch light, a 9W lamp is more than adequate for most situations.
  • Make sure that lights are correctly adjusted so that they only light the area intended and do not throw light onto neighbouring property.
  • Adjust security lights so that they only pick up the movement of persons in the area intended and not beyond.
