GE used metalic tags with this font. Look at Ian's and Darren's M-250R1s. The MV and MH ones weren't metallic though. Crouse-Hinds used metallic MV tags and HPS. i haven't seen a MH Crouse-Hinds light though to comfirm if those were metallic, but I'd assume so.

All the other lumes on this street have identical tags and the metallic tags on theirs have square corners.

Yep GE used both. I'm not 100% sure if these are GE tags, but no other company that I know of has used that font.......

I don't know all the other lumes have those tags on.............

What model/brand are the other lights? They were probably put on there by linmen......

All 1982 Westy..... Well aside from one OVZ that replaced a OV 15 in 07 whose door fell off...........

Those tags may have been ordered from the same comapny by westinghouse. GE hired a label company in the US to make the tags (and still does) instead of makeing the tags themselves. The tags could have just as easily been ordered by the contractor too.

Yeah it sounds like Westy Canada used similar looking tags.

The GE tags are made and were made by the Ohio Label Company.

Well, it seems I missed the changeout crew. When I came home, this got replaced with a LED.

Oh god.

Mississauga is now using LED's as spot replacements. Brampton will probably do the same within the next year or two. Vaughan seemed to be the first to start using LED fixtures

how bright is the LED compared to the HPS and how ugly is the fixture?

Well, I'll let you be the judge of that but at least the light output is and distribution is ok, not as good as a drop lens but I think it's better than those junky FCO lights.

@Model 25: I hope Brampton doesn't spot replace with LED... Mississauga's illumination colours are becoming partially orange and white at night! Brampton seems to keep design standards in clusters at least! Example, FCO has often been implemented in group and not spot uses, although now not true.

I'm suspecting it, but I think over here they've started putting off maintenance on the old HPS lights as they're already undergoing a systemwide changeout to LED. Last year they were spot replacing with FCO lights though.

Over here, a lot of the side streets are now in LED white but the arterials are still lit with HPS yellow. Might make for some pretty interesting aerial shots at night.

Here they had mixed MV and HPS and incandesent for years before standardizing to HPS in the 90s (with some MV left in the system but all incandescents, except for missouts, removed) with the HPS changeout.

Here in the Toronto area:
Incandescent - Lasted until the mid 90s, I've spotted one missout though.
Fluorescent - Lasted in the late 80s, possibly killed off by HPS.
Mercury Vapour - Lasted until the early 90s, killed off by HPS.
Low Pressure Sodium - Used only on the city expressways, killed off by HPS in the 90s-early 2000s.
High Pressure Sodium - First round of changeouts began in 2011, still widely used in the GTA though.
Metal Halide - As far as I know none have been changed out yet, killed off the the last of the incandescent lumes.
Ceramic Metal Halide - Some of the originally quartz MH gumballs might have gotten CMH lamps during relamping.
Induction - Limited to test installs.
LED - First installs in 2010-2011, killing off some HPS.

do you know if that street with 175W MV R37/B2227s is still MV?

They were still there during the summer but I haven't been there since then.
