Well Rte 37 in RI has always had lighting issues at the I-295 interchange. Here's a map of the interchange, complete with all pole numbers and locations. Green dot means pole is present, red dot means missing pole. Blue-purple pencil line denotes wiring faults causing the entire stretch of lighting to be out. No penciling means lights work. As you can see, most of the interchange was knocked out. It happened during out most recent snow storm, which dumped heavy watery snow, which likely seeped into a lot of the old manholes and conduits an shorted stuff out.

Anyway, most of these lights were fixed in 2015. NGrid spent like two weeks with their wiring trucks snaking new wiring between many of the poles and installing lots of brand-new M-250R2s. They had gotten most of the lights working and replaced a few poles but many poles were still left missing and some lights were never fixed.

BUT... Sometime in 2016 one of the ramps went totally out. Then another. Then after a recent snow storm last week, virtually the entire interchange went BLACK! I emailed RIDOT and they said to allow several weeks for planning and more favorable weather conditions. I also reported a string of RIDOT-owned LEDs that were failing on Rte 37. I noticed today that RIDOT was already fixing the LEDs that they owned. No progress on the NGrid lights though. RIDOT's gotta contact them, they'll drag their feet, come out and take a look at what is wrong, come back a month or two later and actually fix the lights, and then next storm we get water will get inside a manhole or something and short the circuit out again. Happens EVERY time! Fortunately most of what they rewired is still working, but they only rewired maybe a quarter to a third of the interchange.

I also like low-wattage incandescent street lights too. I have a late 50s Wheeler crescent moon (sometimes called bird claw) shade light. I'd LOVE to get my hands on a radial wave that is in decent shape (not rotted through and tarnished on the underside) but most left out there today are rotting away. Some teenager would throw a rock at the light or shoot it with a BB gun to blow the bulb out for fun and chip off the ceramic coating on the reflector. The exposed steel would rust and eventually rot through. If the chip was on top, water might even collect and the rust might spread all over.

The amazing thing about the glazed ceramic/porcelain reflectors is that after decades of crap building up on them, as long as there are no chips in the glazing, they will come clean as new with a nice soapy soaked cloth (non-abrasive is a must!) and relatively little effort. Painted reflectors or exposed aluminum reflectors with no enclosure (i.e. refractor with gasket) will tarnish. With painted reflectors a new coat of paint solves the problem but with bare aluminum reflectors, other than sanding it down and buffing it out, there's not much you can do. I usually just hit it with some really fine grit sandpaper that's been soaked in water and gently sand it. It usually lifts off most of the tarnishing without leaving huge gouges in the metal.

I am mainly interested in outdoor and street lighting too. Fluorescent just doesn't interest me that much.

With HID indoors, you often find places way overlit. I think since it's lower CRI you need the extra light to make the store not look dingy? Not sure...

I'm primarily into street lighting (including utility-grade flood lighting and area lighting [aka NEMAs]) but I also like HIDs in general and most magnetic fluorescent fixtures (even some T8s if they're a cool enough design). I also like some traffic signals. Not into specific brands of them but I'd like to emulate RIDOT set-ups, particularly their R-Y-Y 12-12-8 crosswalk set-up.
