Ooo this is one of the early M-250R2s with the metalic NEMA labels. Smile

I think you should remove the voltage, because most of the pics you posted, I was told by another streetlight expert in your area that most of them were actually 240 volt, not 120 volt. So you don't really know the actual voltage of this streetlight....

Most parking streetlights are actually 208 to 480 volts, but I see you post them as 120 volt, which very often is not true....

So I suggest you remove all the voltages unless you really know the voltage...

I don't know what voltage Western Utilities liked, but NGrid owns this area now. This is either 120 or 240V. BTW, Jace did you mean voltage becuase you kept typing watts and wattage. Razz Laughing

Any lights in NGrid turf from the 90s onward are 120V. i know NEES was using 120V lights by the late 80s but i'm not sure about Western Utilities.

LOL I am tired.....

My local electric company, BGE, uses 120 volts for MOST of the installations but I was told some were actually 245 volts....and has a blue photocell instead of black.
However Delmarva Power, uses 240 volts, but I believe the newer ones were 120 volts though.

Maryland state street lighting uses 240 volts in most installations, I believe mostly the ones that uses remote photocell with relay system, although not sure about the self photocell systems.

I also found out New Jersey Turnpike streetlights uses 277 volts as I saw on the labels on the poles which described the fixture giving wattage, voltage, owner name and such LOL.

Most of the electrical companies that maintain street lights have told me they're 120 volts.

But didn't we found out that most of the removed lights that you got pics of in Joe Maurath's collection are actually 240v lights. Confused

@ David; it depends who you talk to. If you talk to someone who works for the boston lights they are 120V, but the lights under NGrid are only 120V in they are from the late 80s-present. Before that 240V reactor ballasts were used with the PC receptacle wired for 120V.
GullWhiz   [Feb 19, 2013 at 02:56 AM]
Yeah, David...the ones that were removed...the ones that you took pics of amd ones that were removed...3 of them were 240 volts....and you said 120 volts......it depends

Man, I was way off.
mercuryvaporrocks   [Feb 19, 2013 at 01:29 PM]
All the street lights in my area are wired for 120 volts.
Antstar85   [Feb 19, 2013 at 03:59 PM]
The only way I can truly tell you the voltage is if you can get a shot of the secondary connections. I know for a fact Massachusetts electric, now national grid, did use both 120 and 240 volt streetlights.
GullWhiz   [Feb 19, 2013 at 04:08 PM]
So David....if you can make close ups of the secondary shots (which I know you are VERY good atmaking close up shots) he can help.....
