Not pedestrian, but many underpasses here in Illinois are lit by SOX fixtures, presumably with 55W bulbs, though they are slowly being replaced by LED. I haven't seen a single burnt-out bulb, surprisingly, but of course, once a bulb burns out, they won't be able to replace them unless they have some large stockpile of bulbs, which they probably do.

Interesting, thanks for sharing.

I’d say the most common configuration for pedestrian underpasses I’ve seen here is typically fluorescent mounted at an angle with a diffuser. The diffusers apparently don’t need any vandal proofing.

Now for let’s say a regular underpass for motorists, MV is very common with HPS is second to that. Most municipalities still maintain them fairly well. Of course corn cobs are invading.

In Finland, mainly that style of fixtures was used, installed in many ways on ceiling and walls, on surface and recessed: https://www.lighting-gallery.net/gallery/displayimage.php?pos=-71526 Usually they have MV lamps, sometimes HPS.
This is a very rare underpass fixture: https://www.lighting-gallery.net/gallery/displayimage.php?pos=-160366

Nowadays, of course, a lot of fixed LEDs are used: https://easyled.fi/en/products/luminaires/pro-via/ and https://www.lumous.fi/en/product-category/bridge-and-tunnel-lighting/

Interesting, thanks for the links!

Are the LEDs glarey at night?

These Easyled fixtures are a bit glary. I heard they don't have any seals, so they collect dust.

Nothing. I don't think I've ever seen an illuminated underpass other than one that's now condemned below a train station, that one had regular 4ft fluorescent fittings protected by custom built grates, only 2-3 worked and the rest was dark.

Everyone avoids them at night so they don't need lights, and if I have to go through one I carry a pocket torch, the bus route I take is pitch dark at night, because all of the wiring for streetlights was overhead and stolen by copper thieves, there's only a few privately owned glarebomb LED floodlights but they only light up garage entrances.

Public streetlights aren't too common in my country, because of arcane legal shenanigans, the section of pavement (if any) between the road and your house is technically a part of your property, so the lighting is up to you. Only state-managed buildings have proper lighting outside, trainstations, and some large parks, but that's really it.

Some neighbourhoods have agreed to use the same type of lights so they purchase in bulk and they all look the same, -awful 6500K LEDs- but other parts of the city are whatever people had: floodlights, cheap flush mount luminaires, hanging holders with, there's strings too, and some old dead linear halogens that are dark patches now.
