"Mougl"? I'm going to use that for my new band name.

Doesn't even look Sylvania-made anymore! What happened to the brass screw shell? The end of the arc tube support looks interesting too. Very unusual.

We just call it E39 or E40, possibly GES.

In the US I've never heard the "E-number" designations used. We've got "Candelabra" (E12), Intermediate (E17?), Medium (E26, sometimes called "Edison base"), and Mogul (E39). There's also such a thing as "Admedium" but I'm unsure really what it is. I think it's slightly larger than a medium base (makes sense anyway, admedium --> "add-medium", larger lol). Some of the first 100W MV lamps in an A-shape were of the admedium variety.

Here, the most common sizes for screw fittings (rather than bayonet caps) are E14 (or SES - Small Edison Screw), E27 (ES or Edison Screw) and E40 (GES or Goliath Edison Screw). There are smaller sizes for things like torch bulbs, but those are the most common ones.

MV lamps up to 125W historically had B22d-3 (3-pin BC) caps, then a few years ago they switched to E27, which I think was a bad move, as MV lamps don't much like being plugged directly into 240V

HPS and MH lamps have always used E27 for the smaller sizes and E40 from about 250W upwards.

Yeah I never understood who thought it was a good idea for HIDs to use the same socket base as an incandescent but aside from LPS, which never caught on on a large scale, most lamps are screw-in here. The twist-lock CFLs (GU24 base) came out several years ago for those energy grant retrofit programs. They'd install lights with GU24 base sockets so standard medium base incandescents couldn't be back-retrofitted.

That's a typical 2016-present Sylvania HPS lamp with the loop at the top. I got a few of these in street lights replaced by LED earlier this year. The nickel plated base is from 2017 on, but still has the Sylvania design.

Sorry to burst your bubble, but that lamp is not well made...its junk when compared to what Sylvania made, even just five years ago.

Yup, they rattle badly. Prolly fails after 1-2 years now.

Hey Mike, you should take a gander to see this: https://en.wikipedia.org/wiki/Edison_screw

Pretty, please no more Chinese failure.

This is Lowe's. The lamps on the bottom shelf are branded "Utilitech", Lowe's in-house brand.

BTW, is it just me or does that lamp look used? Normally HPS lamps I've seen aren't blackened on the ends when new...

I'm guessing they added some material on the electrodes, that make the arc tube look partially used. Is my guess.

This is typical for a Sylvania Lumalux lamp. I remember this being the case back in the '80s and '90s. I think that the darkened ends are from them pretesting the lamp.

That is correct, they do a full run up for the pre-tests.

Oh wow I'm surprised to hear of a company out there that still tests every lamp! Do the others do this as well?

Sorry, I've always had trouble with things like "pre" test. If you're testing something, you're testing it. Pre means before, so a before testing test..? Sounds odd.

You can never be too certain. All that testing done at the factory must explain why Sylvania HPS lamps don't last very long once put into service. Half their rated life is spent in the factory.

LOL Yeah I was just poking fun at the fact that many HPS Sylvania lamps nowadays don't last. Westinghouse had an ad back in the day saying all their lifeguard lamps were tested for 1 hour before being packaged up.
