It was good to see the LightAware charity highlighting the actual drawback of blue-rich LEDs within the dialogue on the rise in gentle air pollution (Letters, 7 November). I cherished Jacqueline Yallop’s wealthy and vivid article (All the pieces from our sleep to our hormones depends on the darkish. So why are we so intent on destroying it?, 31 October), however felt it missed this necessary level: it isn’t simply the amount of sunshine that has modified in latest a long time, however the high quality of that gentle.

The push to transition to LED lighting resulted in a botched job: councils all through the UK put in gentle in our public buildings and areas, and in our streets, that was far too intense and contained an excessive amount of blue gentle. That is exactly the wavelength of sunshine that almost all disrupts the circadian rhythm –not simply sleep however nearly each different physiological course of – in people and the remainder of the pure world.

A examine by Darkish Sky Worldwide summarises the accessible science on gentle air pollution. It questions whether or not the transition to LED avenue lighting supplies any significant environmental profit, and talks of “greenwash”. There’s little question in regards to the hurt brought on to the general well being and wellbeing of individuals, with the lives of light-sensitive folks being devastated, and by the disruption of pure ecosystems. It has additionally exacerbated gentle air pollution as a result of approach blue gentle scatters and creates extra “sky glow” – the smudgy veil of synthetic gentle that obscures the celebs.

Blue-rich LEDs have made our world uglier, altering the color of our cities and cities from a mushy orange glow to a harsh, gloomy glare. Gentle doesn’t simply illuminate our environment, it creates the very world that we understand and interacts with life in profound and delicate methods. We have to use it with nice care and warning.
