Recent reports carried out by governments in Europe and the United States have investigated the safety and appropriateness of LED as a lighting source.
Scrutiny of this fast emergening technology has revealed some doubts as to its suitabliity in lighting the public realm.
|March 24, 2019 | Revision of the EU Green Public Procurement Criteria for Road Lighting and traffic signals | In residential areas, in order to reduce the risk of human annoyance, the CCT of light sources shall be ≤3000K and a dimming or switch-off programme shall be implemented Read More >|
|February 17, 2019 | Health impact assessment of introducing LED street lighting in Stockport | Evidence indicates that exposure to artificial bright light during the night-time suppresses melatonin secretion, increases sleep onset latency and increases alertness. Chronic ALAN exposure can cause circadian rhythm misalignment which may have negative effects on the psychological, cardiovascular and/or metabolic functions. Read More >|
|July 12, 2018 | SCHEER Report into Potential Risks to Human Health of LEDs | Children have a higher sensitivity to blue light and although emissions may not be harmful, blue LEDs (between 400 nm and 500 nm) may be very dazzling and may induce photochemical retinopathy, which is a concern especially for children below three years of age.

|March 2, 2018 | Chief Medical Officer annual report 2017: health impacts of all pollution – what do we know? | Gov.uk Some LED installations, however, have LED chips visible, which can form a source of glare. An extreme example is daylight-running lights on cars. These are clearly visible to other road users and pedestrians. Read More >|
|February 1, 2017 | Street Lighting and Blue Light, Frequently Asked Questions | US Department of Energy Spectrum, light level measured at the eye, duration of exposure, and timing of exposure relative to an individual’s circadian cycle are believed to be the principal contributing factors to light’s effects on health.

|October 25, 2010 | ANSES Report 2010 | The blue light necessary to obtain white LEDs causes toxic stress to the retina. Children are particularly sensitive to this risk, as their crystalline lens is still developing and is unable to filter the light efficiently. Read More >|
