Lampholders

I've got some table lamps with switched white plastic lampholders.



They're currently fitted with UK-style bayonet fittings (B22d socket with



0.5" threaded fitting to the lampbase) and I want to change them over to US-style Edison-screw (E26) type fittings.

However, I really need to keep the style of the lampholder the same. I've been looking for white plastic push switch lampholders everywhere and can't find them. Any suggestions as the where I can get them in So Calif?



Alternatively, if I were to but the European-style Edison-screw (E27) switched lampholder, would a US E26 bulb fit ... I know that the specs are similar, but I don't know *how* similar?



Cheers

The brass ones look better than the plastic IMO!

Hope it helps

Thanks for this ... but it's not what I want. I emigrated from the UK to the US last year (I still have things in boxes!), and I want to convert my UK table lamps. It seems that the only fittings I can get are metal (which I don't want) or black plastic (which I will accept if I have to). I wondered about using a bayonet to ES adaptor, but only if the US ES bulbs (E26) can be fitted into a European ES socket (E27). Hey ho!

Cheers

Craft stores may have them. Just a wild guess. If not, get black ones and paint them. John

Do they call them E26 in America? I've never seen that anywhere. I don't have any American GLS lamps, but I do have lots of large photographic flashbulbs, which old American books on the subject say fit normal (in the US) screw fit domestic lampholders. This was in the days before purpose-made flashbulbs and smaller bulbs. The caps on the bulbs are the same as the E27 type used in Europe. Maybe one was rounded up from an original specification in inches, and the other was rounded down.

I would avoid BC-ES adaptors in table lamps if you can, the adaptors are quite long, and the bulb will be quite a bit higher than it should be, this may, or may not, matter, depending on the size of bulb and shade. Also, the whole bulb/adaptor combinator will be supported by the BC lampholder, which tend to provide a rather poor support.

What sort of shades do you have, the ones that clip onto the bulb, or the ones which are held by a ring on the lampholder? If the later, tou have another problem, the ES holders are larger, and the shade will not fit.

Good point about the shades and bulkiness of the adaptors .... I've found a local source of BC 130V lamps so I'm going to go and buy some. At $5 a pop for a basic lamp that's about 10 times the price of a standard US ES bulb! But beggars can't be choosers!

Thanks to all for your help.

- now that I've checked this out, and discovered that will be a problem, I'

if you run the 130v lamps on 110v you will get a greatly reduced light output but on the other hand a very long lamp life!!
