The occurrence of light pollution has become common in most countries today. Yet most people are not aware of it and consequently do not take an action.
Light pollution is artificial light in places where there is no need for it or even in places where it causes damage. Characteristic examples of harmful lighting are empty areas, over-illuminated trees, monuments or undesirable light from street lamps shining into windows.
Studies have shown that harmful lighting causes isomnia and other health problems, and can even cause car accidents. This is not just an isolated issue of several incorrectly placed light sources. It is an issue which affects a great part of the developed world.
In addition to outdoor light pollution, we face harmful light coming from our mobile devices. Many are unaware of the dangers they are exposed to by excessive use of screens. For this reason we have decided to raise awareness of indoor and outdoor light pollution.
The emitted-light intensity is measured on the ground by the foot of the lamp (recording the maximum value) and between the lamps (recording the minimum value). Color temperature is measured by a spectrometer. Every graph is saved for a possible further examination.
You can help us by sending us pictures of harmful lighting to the email provided in Contacts.
We also measure other light sources, for example billboards.
