Clarification of "pin size"[edit]

Wanted to suggest replacing "The suffix after the G indicates the pin size. " with "The NUMERIC suffix after the G indicates the pin SPACING (CENTER TO CENTER)." if this is the correct interpretation.

Thanks. —Preceding unsigned comment added by 208.252.48.163 (talk) 16:12, 14 January 2008 (UTC)[reply]

Remove GU10 since it's a bayonet mount?[edit]

Per Mion's recent edit removing GU24 because it belongs on the bayonet mount page (see drawing at Lighting Research Center), I believe the GU10 should also be moved (see GU10 diagram on Don's bulbs). The GU10 is currently listed on the bayonet mount page as well.

Good question, on this link [1], it is presented as "GU10 "(bipin twist-lock)", but i think the fact that you have to twist it to secure it makes it a bayonet mount. Mion (talk) 23:37, 6 July 2008 (UTC)[reply]

But funny, they made a competition, the award winning design for the new fitting is the same as the old GU10, Mion (talk) 23:47, 6 July 2008 (UTC)[reply]

That matter should be easy to settle, as bipin "is a standard from the IEC", so we only need to know what the pertaining IEC standards are, and what they say about the matter. I note that this info is not yet here. ;) Paradoctor (talk) 02:13, 28 September 2009 (UTC)[reply]

Pictures needed[edit]

This article is really pretty useless without example photos of the different kinds of pins. Can anyone contribute? -- Evertype·✆ 21:03, 1 October 2008 (UTC)[reply]

Indian name meaning[edit]

Going through the page's history, I noticed that Bipin is also a name. Two different anon contributions to that effect were removed[2][3] without giving a reason. Why? Paradoctor (talk) 02:00, 28 September 2009 (UTC)[reply]

This looks like an RS. Paradoctor (talk) 22:37, 12 November 2009 (UTC)[reply]

G9 light[edit]

Below the content of that stub before I made a redirect out of it:

G9 bipin halogen light bulbs are used in downlights and spotlights and have a similar physical profile to the more common 12 Volt halogen bulbs, but operate at mains voltage. This means they do not require a transformer to step the voltage down, and consequently can be dimmed using standard dimmers.

Illustrations[edit]

I think we want illustrations of typical sockets, at least for GU.
Pictures are good, but some technical drawings would probably be preferable.

Your thoughts? Paradoctor (talk) 12:05, 2 March 2010 (UTC)[reply]

JC type??[edit]

In US descriptions I only find "JC" Could someone who knows what that refers to plse add a reference or a paragraph here? Thanks. 99.11.160.111 (talk) 17:04, 2 August 2011 (UTC)[reply]

reference is broken[edit]

There is only one reference in this article, and the link is currently broken. — Preceding unsigned comment added by 95.33.205.85 (talk) 09:10, 22 January 2012 (UTC)[reply]

Predecessor of multi-pin sockets?[edit]

Would it be fair to say that this was a predecessor to the connectors used between vacuum tubes and tube sockets, and eventually integrated circuits, such as DIP packages and sockets? (What sort of citation would be required for that?) KazKylheku (talk) 21:48, 11 August 2014 (UTC)[reply]

January 2018 rename suggested[edit]

This article is about lamp bases. The term "bi-pin connector" gets almost no hits on Google Books except for those enterprising folks who make money republishing Wikipedia articles. Suggest this article is renamed Bi-pin lamp base to more accurately reflect its content. --Wtshymanski (talk) 20:41, 1 January 2018 (UTC)[reply]

The term "lamp base" in common usage refers to the ornamental base of a table lamp, although it is sometimes used in North America to refer to the connector part of a lamp.

The correct term for the devices described in this article is "lamp cap".

The mating part is called a "lampholder"

The primary designation "G" is used for lamp caps which have two or more projecting pins, this includes bi-pin caps, but also those having 4 contacts, such as G17q-7, G10q and GX38q.

Lamp caps and lampholders are standardized in IEC 60061 which also includes Edison screw, bayonet caps (mixed in with a general article on bayonet mounts) and various other lamp cap types. There is another overlapping article called Lightbulb socket (note the inaccurate description) which also decribes lamp caps.

IEC 60061 "Lamp caps and holders together with gauges for the control of interchangeability and safety" is split into four parts:

IEC 60061-1 "Part 1: Lamp caps"

IEC 60061-2 "Part 2: Lampholders"

IEC 60061-3 "Part 3: Gauges"

IEC 60061-4 "Part 4: Guidelines and general information"

A preview of the IEC 60061 database is available at: https://webstore.iec.ch/preview/info_iec60061_DB.pdf This includes lists of the standard sheets contained in each part of the standard, about 750 in all.

ANSI C81.61-2016 "American National Standard for Electric Lamp Bases— Specifications for Bases (Caps) for Electric Lamps" is the US standard based on IEC 60061

"EN 60061" (same parts as the IEC original) is the Cenelec (European) version of the IEC standard.

"BS EN 60061" (same parts as the IEC original) is the British Standards version of the Cenelec standard.

All of the current WP articles are somewhat inadequate, and I would suggest a single article, perhaps titled simply IEC 60061 (with appropriate redirects), would be an appropriate solution to the current mess. JimmiCheddar (talk) 17:56, 3 January 2018 (UTC)[reply]

A single article, merging Edison screw, bayonets and all the other possibilities, then placed under an unrecognisable name would not be an improvement. Andy Dingley (talk) 19:03, 3 January 2018 (UTC)[reply]

IEC 60309, IEC 60320, IEC 62196 and IEC 60269 would seem to be appropriate precedents? In any case, the current mess is hardly defensible. JimmiCheddar (talk) 20:21, 3 January 2018 (UTC)[reply]

Comment: I don't have an opinion about what this should be renamed to, but I would agree that "bi-pin connector" is pretty much useless. AFAIK, "bi-pin connector" is a generic term for any electrical connector that has two pins (for example, this). Lambtron (talk) 20:38, 3 January 2018 (UTC)[reply]

I agree with Andy Dingley in opposing a merge of different bulb bases. And it is sad to hear ethnocentric pronouncements that "lamp cap" is the only correct term for the metal connector part of an electric lamp, and that "socket" is "incorrect as a description of the mating part." (Reminds me of "The fish knives that were in my mother's house are the only correct fish knives." ). Edison (talk) 04:40, 11 April 2018 (UTC)[reply]
