Hi there!

I would like to know if there would be any suitable constellation for ballasting American mercury lamps on European 230V 50Hz line.

To be honest, I like these clear MV lamps that much, and they are so (...) rare over here that I don't want to just use my few very rare clear MV lamps for general lighting purposes. So I'm thinking about to buy some clear American MV lamps - Usually they should fit into E27 bases.

What are the specifications of those different MV bulbs, in particular:

50W
75W
100W
175W

And is there a possibility to run them here, even with little dropped lifetime because of no proper gear?

Regards... Marc

Yeah, although it's nice that a lot of Cooper's LED fixtures are real cobra head. Plus they still make the OVX, RMA and Vanguard III fixtures that I like, in HPS.

Well, IDK but I usually wait, unless the city or municipalities (which they're customers for the utility companies for the streetlighting) are going LED. Sometimes they brag about it on newspapers or on the city's website news section. But for DOT streetlighting, you have to be right on-time or at the right time, if you see the bucket truck.

Yet I haven't asked CPE about the changeout to LED in Tomball.

Light sets with a receptacle on the end have two hots in parallel and one neutral. One of the hot wires has the lamps and the other one supplies power to the receptacle.

I saw how Duke Energy has a map now, where you can report which streetlights that are dayburning or out, etc. You have to give your name and phone number and can leave other information such as the gate code, pole number, etc. But I wonder if I reported a broken street light, and they needed to replace the fixture, if I could put in the comment section to ask if I could have the old one, if they would save it for me or let me have it or not?

That might be a possible option, but my dad wants them recessed.

I bought a Commercial Electric LED light that can be installed to either a can light or a 4" box. I'm not sure which cans it will work with though, and it mounts to the surface of the can, so it's not truly recessed, but more like a flush mount fixture. They're also wet location rated.

Thanks for the info guys. Also I was thinking we have a plastic blowmold candle and it has a fused plug also, but the bigger kind like you see on electric candles or fans, etc. But we also have a blowmold toy soldier and it's newer than the candle but it doesn't have a fused plug oddly.

I have seen some old Christmas light sets probably from the 1920s, and they had a round plug with a receptacle on it as well, so those must have been around for a long time before fused plugs were added.

Also most of our light strings have an extra receptacle on the end of the string, and I'm not sure how long they did that. But our pattern or chaser lights don't have a receptacle probably since it wouldn't get constant power due to the controller.
