Only what you need
Use full cutoff shielding that directs all light toward downward angles. Illuminate only the area needed and avoid light trespass.
Only when you need it
Use timers and motion sensors to illuminate only when needed.
Not more than needed
Lights that are too bright cause glare and deep shadows. Wasted light is wasted energy.
Not bluer than needed
Use “warm white” LEDs instead of harsher whites. Blue light causes much stronger glare and is linked to health and environmental problems.
These simple steps will eliminate light pollution!
