We put a yellow bulb for our house porch light, and it doesn’t even attract bugs! It’s like a win/win.

Poggervania@kbin.social 1 year agoAdditionally, you’d use a different kind of light for street lights. On the island of Hawaii, that island specifically has a light pollution law that mandates all street lights have to use an orange light bulb, and they can only be in certain places. It’s amazing because you can see so many stars in the night sky.
If city lights are gonna be on 24/7, we should start to see if we can get traction for reduced brightness and installing less light polluting lights.

It's technically not orange light bulbs they have to use, it's a specific lamp style called 'low pressure sodium'
Here's an article that explains the reasoning behind Hawaii's lighting sources and the regulations:

That site is claiming that phosphor-converted amber LEDs provide all the benefits of low-pressure sodium. They do not; one of the benefits of LPS is that astronomers have a very narrow frequency band to filter out, while PC amber is much wider. Monochromatic amber LEDs are more comparable to LPS.
