It's more like someone standing on public ground outside movie theatre holding up signs like, "Bruce Willis has been dead the whole time!" ""Verbal" Kint makes up his whole testimony on the spot - he's actually Keyser Soze!" "Dr. Mann is a liar, and the "ghost" pushing books off Murphy’s childhood bookshelf is her father, through a time portal from within the black hole!", etc, and then people skip buying a ticket and head back home. Now the plot-spoiler has decided to make it up to the movie theatre by buying some tickets from them.

The funny thing is there's not that much difference in the raw bulb efficiencies - LPS is slightly lower, but not dramatically. But LPS have more fixture losses (the bulbs are omnidirectional), ballast losses, inefficient dimming (and only to slight degrees) for morning/evening, and so on. LED's high CRI (vs. LPS's virtually nonexistent CRI) can sometimes mean you can use less light, too. In practice, you can use something like 30-40% the electricity with LED streetlamps as with LPS, despite the raw bulb figures not being very different.

But no question that LED is much worse for astronomy. LPS was almost a pure spectral line, very easy to exclude. White LEDs use phosphors and deliver a broad spectrum white (apart from the source's blue peak). Pretty much the worst spectrum you could have apart from incandescent. : It kind of sucks that we have to use phosphors in the first place, as they're wasteful - but unfortunately, LEDs have a "green gap"; in the green spectrum, existing tech has a dramatic drop in output and efficiency (and corresponding increase in price) - while green is what our eyes see best. There's still ongoing work to fill it, but it's been a slog. If we could skip the phosphor and just have a mix of different coloured LEDs, the fixtures would be even more efficient, and it would be much easier for astronomers to filter (esp. if the frequencies were standardized)

You know that arctic apples and innate potatoes both use the exact same PPO silencing tech, and have been on the market for years? Innate potatoes also contain less asparagine, the amino acid that turns into the carcinogen acrylamide when frying.

Do also remember that while these are "GMO", they're not transgenic. They simply have genes shut off - no new genes.
