70W to replace 175W MV? I guess if the lamp is really dim but IMO replacements should be based on the initial lumens since otherwise all the 100W MV lights in RI would've been replaced with 35W HPS lol. I've seen a lot of cases where NGrid will replace a MV with the same wattage HPS so they can keep billing the city for the same wattage. They do it all the time with 100W MV and sometimes with 400W MV too. I personally like it when they replace 100W Mv with 100W HPS since the orange light makes it harder to see. The extra lumens make up for the inability to see under the light. A brand new 100W MV lamp actually does a better job lighting the road than a 70W HPS and the 70W HPS is rated at 2300 lumens greater!
I wish they would have used 70W HPS widespread here instead of 50W HPS because 50W HPS is pretty useless. Granted, a lot of the 50W HPS lights here replaced 1000L incandescent lights so that was probably a great improvement in brightness but for 100W MV, 50W HPS doesn't cut it. Blackstone Valley Electric and Newport Electric (EUA) used 70W HPS but Narragansett Electric (NEES) used 50W HPS. Narragansett Electric was by far the largest utility in RI. BVE was a far 2nd and Newport Electric being the 3rd smallest. The absolute smallest would be Pascoag Utility District, which is a municipal utility in Burrillville, RI. Now of course all of RI (excluding Pascoag Utility) is National Grid. But the utility borders still stand for the most part between NEES and EUA cities and towns.
It's not LED.
