Hampton thats a NICE town I loved it! But sadly now HPS is creeping in the business area by the beach is now mostly HPS. Do they still service the mercs? I understand that area is served by a small utility.
Yeah I love coming here every year. It's sad HPS is creeping in but the good thing is the utility here still services mercs. The utility is small but they merged some years back with the utility that serves concord NH. They are known as UNITIL and they only have 100,000 electric coustomers in MA and NH.
I saw some M-250R2s off of a rest/boos station on I-93 in the Manchester area that have 175W HPS stickers. The M-250Rs have blue 17s so i'm guessing all are 175W MV and GE had a fluke with that batch of R2s.
The next pole from this is OV-25, that fixture is still there. I remember this road being entirely MV. Now there is maybe 8 HPS fixtures mixed in. Thing was is they were installing mercs right up until the ban. They should of used MH fixtures to keep that "merc" feel to the road.
Walking around town here, I noticed a brand new M-250R2 250 watt MV fixture installed where a 175 watt M-250A once stood within the last year. Seems like they may of had some old stock they were getting rid of.
In Los Angeles, LADWP the utility still installs leftover GE M-400R3 mercs like this one as replacements once in a while, only for series circuits. Southern California Edison offers Pulse Start Metal Halide street lights now but I have seen widespread installations in only one city so far, heres a pic.
Narragansett Electric stopped installing mercs in the early 1990s. the very last mercs installed were T&B 100W 113s, but in small numbers. I know of very few left. They were installing both mercs and HPS interchangeably for a short while. They had left a lot of remote ballasted mercs up until NGrid bought out Narragansett Electric's parent company, the New England Electric System. NGrid got rid of most of the 175W mercs a few years back but still relamp the 100 watters from what i can tell. Once stock is out so will the lumes most likely.
Duquesne Light stopped stocking mercury vapor lamps in 2009, the GE mercury vapor lamps they were using only lasted 3-4 years which is why they gave up relamping their mercury vapor street lights.
