Yay! Keep in mind though, this doesn't stop manufacturers from voluntarily discontinuing MV or other HID lamps nor does it prevent the trend of worse and worse quality of HID lamps from continuing. But at least MV lamps will be around for the time being.

I dont think Iwasaki plan on dropping MV technology - And they are great lamps

The remaining MVs in So Cal are still being serviced. And quite a few MV lamps still in use for outdoor lighting such as yard lights, strip malls etc.

That's not what I'd expect from California. The MVs here were being serviced until maybe a year or two ago--now they just install a new LED fixture.

Here they had stopped maintaining 175, 400, and 1000W mercs around 2000. They kept relamping 100W mercs for whatever reason (I think because there were so many of them left when NGrid bought out NECo in 2000) until around 2014. Now they replace all mercs with HPS upon needing service. No LEDs on utility poles here, though RIDOT is installing some LEDs. RIDOT still relamps existing HPS fixtures and spot replaces with an equal light. If it's a drop lens HPS, it gets replaced with a drop lens HPS if it fails and if it's an FCO HPS it gets replaced with an FCO HPS when it fails. They don't mix drop lens and HPS (except in very rare instances; only seen it a couple of times) and so far haven't mixed HPS and LED.

So far RIDOT has swapped out the HPS lights at all the Park-N-Ride lots with LEDs, Exits 1 and 2 on I-95 near Connecticut (at these interchanges they replaced the NGrid-owned truss poles with their own RIDOT-owned metered davits), Exit 7 on I-295 (just a cobrahead-to-panel swap), Exits 6 and 7 on RI Route 4 (cobrahead-to-panel swap, keeping the RIDOT poles), the Hartford Avenue exit on US Route 6, and the Reservoir Ave exit on RI Rte 10, where you can see the new poles were up but the old poles were not yet removed.

FYI, those trusses on Route 10 originally held GE Form 400 Powerpacks! The truss poles were all owned by National Grid (then it was Narragansett Electric Company before NGrid bought them out). The lights are "rented" by the state DOT just like wood pole lights are "rented" to the city. I don't think the metal poles lights are charged the same way wood pole lights are though. The metal poles are unmetered but I don't think it's a per-light charge. At any rate, RIDOT is eventually going to replace all the remaining NGrid-owned lights with their own RIDOT-owned poles, which will be metered. That way RIDOT will only get charged for usage and they can program the relay cabinets to shut the lights off in the middle of the night. The NGrid poles have photocells and run dusk-to-dawn (that is, when there aren't wiring issues; NGrid is horrible at maintaining the freeway lights).

The MVs here were being serviced until maybe a year or two ago--now they just install a new LED fixture.

@ nicksfans: Would there be a link somewhere with an official practice or procedure for servicing MV fixtures in SC? I'd be very interested in closely looking at this.

Of course they wont. They make the best lamps

Added something to Wikipedia

That Wikipedia article is not 100% accurate. Definitely needs some tweaking.

yeah. It said that the energy consumption goes up twice. Some peeps.

Being a grammar (...) I want to cry reading that.

Being a grammar (...), I want to cry when someone doesn't use the Oxford comma or just flat out forgets them.
I'd edit but I need to make a wiki account.

Yeah Oxford commas are technically optional, but I agree with you. I cringe when I don't see it used in professional documents like a news article or textbook. Or the misuse of "your/you're" or "their/there/they're" lol.

Yeah, when I see it on tv show descriptions I cringe a bit. Ever since I was in kindergarten, we were taught to use commas after everything in a list. I know that British English doesn't usually include the Oxford comma. And I made a wiki account, I'm called NEMAbuckethead.

Wow, this is great news! A sweeter Christmas indeed!
