What light bulbs can you use to to decrease light pollution?

Answer 1

No light bulbs can reduce light pollution. But you can reduce a number of bulbs in your house or building. If you own a building, you could reduce and\or space apart the number of light pannals from each other.

Answer 2

Only illuminate areas where is necessary and replace streetlights that send light up in to the sky with streetlights that re-direct light downwards. It is also recommended that you turn your house lights off in the middle of the night.

Answer 3

One good way to reduce light pollution is by shielding street lights so that they re-direct light downwards, rather than up into the night sky. Also, at night, turn off all unnecessary lights in the house to stop light trespass (when unwanted light enters another one's property).

Answer 4

Only illuminate the areas that need it and replace streetlight which send light up into the sky with ones that re-direct the light downwards.
