LEDs offer many benefits, such as efficiency and controllability, but scientific studies and advocacy groups have raised concerns about their long-term ecological and health effects, their contributions to "skyglow" and other types of light pollution, and even their realizable energy-savings.
The problem, though, is that I live under skies awash with skyglow, as many of us do.
Physicists created a computer programme called SkyGlow that is able to quantify the impact of light pollution, potentially able to influence changes in street lighting other sources of light pollution."Light pollution outside of towns caused by light leaking from towns is not only an economic problem but also a problem for astronomers who cannot observe the skies," said Frantisek Kundracik from the Faculty of Maths, Physics and IT, as quoted by the SITA newswire.
Light that is directed upwards or reflected from the ground into the sky is called skyglow. These particles of light, or photons, are scattered by dust in the air and often wash out the light coming from stars.

Transitions to LED lighting greatly increase this 'skyglow,' because the clear sky predominantly scatters short-wavelength light," the study explains.

IDA's Fixture Seal of Approval program certifies outdoor lighting fixtures as being Dark Sky Friendly, meaning that they minimize glare while reducing light trespass and skyglow. Certification criteria includes a CCT of 3000K or below and a U0 rating, emitting no light above 90 degrees.
Campaigners argue that the huge increase in light pollution from extravagant LED displays not only creates 'skyglow' that blots out the stars, but also affects night time predators, especially birds, who have biologically evolved to be dependent on an environment with a minimum amount of pitch black darkness.
The effect was believed to be "skyglow" - a spectacle created by light-pollution, the main cause being street lamps.

Today, there is a whole "dark sky movement" of professional and amateur astronomers alarmed that nocturnal skyglow from urban areas is blotting out the sight of stars.
