What can we do against light pollution?

  1. Every light needs to be justifiable
  2. Limit the use of light to when it is needed
  3. Direct the light to where it is needed
  4. Reduce the light intensity to the minimum needed
  5. Use light spectra adapted to the environment
  6. When using white light, then in ‚warm‘ colour temperature (less than 3000 Kelvin)
