Here's a second scene pic of the Cambridge Service Centre, this one shows the gas station area of it along with a nice row of GE M-400As as well as some other lumes.
If you want to be technical, it would say "Mercuy Luminaire" Mine doesn't have a ballast label. Inside or out. It has this yellow card clipped onto a wire inside.
A little update on this, the buildings have all been demolished and McDonalds and Petrol Canada signs taken down but the streetlights and street signs are still up.
Yeah lights seem to be the last thing to go. When the all so klutzy RIDOT does major road work, most of the breakaway bases activate sending the poles and lights down.... Then they put up a new light and it falls again when it gets hit my their machines again. What a waste of lights.
Yeah, sadly I think they took down the lights on the eastbound side sometime last December though. I think the last pair of Ovalites from this lot might be still up though.
I don't have a X-ray camera that can read ballast labels
