Light pollution is a growing threat to astronomy, but a new streetlamp technology could restore clear views of the night sky.
Light-emitting diodes (LEDs) consume only about 10% of the electricity required by traditional incandescent lights and last up to 25 times longer, so it’s no surprise that they have become commonplace over the past two decades.
When an entire city gets fitted with energy-saving LED lamps, this bright light scatters through Earth’s atmosphere and makes the sky glow with greater intensity.
In fact, the light pollution problem is worsening so fast that it offsets some of the improvements gained through advancements in telescope technology.
"Modern telescopes are highly sensitive and feel the impact of outdoor lighting of cities located at the distance of 50 or even 200 kilometers [30 to 120 miles].
The experiments, conducted at an observatory in the Caucasus Mountains in Russia, showed that the technology, dubbed the DarkSkyProtector, could reduce unwanted sky glow in astronomical images by 94%.

This skips over a key point that connects the sense of para 2 and 3: “But there is a downside to LEDs: They’re much brighter than old-fashioned energy-guzzling light bulbs.” It also omits any explanation of what the new technology is or how it works. Bad bot.
This is the best summary I could come up with:
