There used to be a place with some low pressure sodium street lamps but I don't have any photos of those! Here's just HPS.

i was just thinking this on the way home the other night

everyone's house has piercing exterior lights or absurdly bright motion activated lights that will turn on suddely and just absolutely blind you if you're dark adapted

walking past those new LED streetlights with their sunlike single bright spot and steely blue light is like having a laser pointed directly into your eyeballs

but there's one place i go past that still has sodium lamps. they're still easy to see by, but they're not actively painful to dark-adapted eyes

that distinctive orange glow is warm and comfortable and inviting

they won't cook your corneas

ALL HAIL THE SODIUM LAMP

I looked into it, and it looks like LED conversion projects have been going on in the state since like 2012. I'm getting mixed messages about whether the Big Island has switched over or not. If they are LEDs, they must be indistinguishable from the solid-yellow sodium lights because I'm seeing people talk about it on Reddit as recently as a month ago.

Thanks for the correction! It's a fun fact I like telling people about, so I want to make sure I'm not spreading misinformation :).

I remember this being a thing when I moved to the CA Bay Area for awhile, there were tons of sodium lamps. It made me really associate orange light with being in San Jose (presumably because of the observatory out there)

it's very likely! HPS is usually used for flowering while ceramic metal halide (CMH) has a more useful spectrum for growth. LED is definitely a huge amount of money to drop at once, but they pay for themselves super quickly. you have way more flexibility with LEDs as well since they don't give out as much heat as HPS.
