Hello all,
I'm considering buying a chandelier in a US web-shop, and as far as
I know there is different lamp fitting standard there (E26, if I'm not
mistaken, in the US, and E27 here in the Netherlands). My question is
-- does anyone has an experience with this subject? Will I be able to
use E27 bulbs in E26 fittings -- I saw that some fittings (sold
separately) are even marked as E26/E27 now. Or will I need to place
new fittings in the chandelier (and I think it's a bit risky, as I'm
not sure that the fitting fixture will allow for it).
Any advice will be very appreciated.
Thanks in advance and kind regards
olejorik |

What's the difference between 120v 60Hz and 240v 50Hz. Check the
insulation rating buddy.

Yes, I thought about this, Rob. The sales person in the web shop said
that the lamp can be converted by only rewiring the fitting, that's
why I ask the question. |

Certainly from the standpoint of good electrical and fire safety practice, a
rewiring and change of sockets would be required. Any residential lighting
fixture for sale in North America is likely to be UL and/or CSA listed via a
label and to have another label that shows the maximum lamp wattage to be
used. That maximum lamp wattage should apply to the rewired and resocketed
fixture as well.
An alternative would be to power the fixture via a step-down transformer
using the intended lamps. Replacement lamps are easily available anywhere
today via web stores too.

That will include replacement of the lampholders, so the
E26/E27 question is irrelevant. (US lampholders don't even
come close to being acceptable in Europe, and that's nothing
to do with the different size.)

Now I'm confused.
When I moved to Germany I brought US lamps. Of course I needed
locally purchased 220V bulbs and an adaptor (not a transformer) to fit
the outlet, but after that they worked fine. All my coworkers have
done the same without problems.
(I know I'm using lamp and bulb in nonstandard ways, sorry. I mean I
brought that big object that sits on the table from the US and I
bought that little pear shaped glass thing at the German store.) |

so it means that E27 bulbs can be mounted without probelms to E26
fitting? --
This sound encouraging, so maybe I just need to buy that lamp and try
it.

I don't know if it means that or not. Some of the comments above to
the contrary are by knowledgable people, and I am definitely not an
expert.
However, the US armed forces has been sending families to live in
Europe for many decades. At one time there were several hundred
thousand Americans here, now there's only a fraction of that but it is
still a significant number. And most of us brought our own lamps
because that's the advice we were given. Perhaps there is a risk I'm
unaware of, I dunno. But there are lots of us doing it. So if anyone
could address the risk I'd appreciate it. |

It will usually go in, sometimes a bit stiff. Sometimes when you
unscrew it, some bit of the lampholder unscrews instead and the
thing falls to bits. (EU ES lampholders haven't been allowed to
be constructed so they can come apart that way for years.)
In EU countries with polarised mains supplies, the live connection
must be the tip and not the screw, and unpolarised connectors are
not allowed on appliances with ES lampholders.
It won't meet EU regs for other reasons. In some EU countries,
that makes it illegal to import (not UK), and in other countries
that makes it illegal to sell (UK).

Ah. Now that is significant. All our lamps have unpolarized plugs
and can be inserted either way, so there is no way to tell whether the
tip would be live or not.
Also, all US lamps will have flat pronged plugs. You can make contact
while inserting them into an outlet, as opposed to EU plugs which are
completely covered when hot. Of course we must insert the US plug
into an adaptor which does have the round insulated prong, but when
unplugging one usually the adaptor stays in place and the flat prong
is exposed.
Some lamps probably have wire nuts as part of assembly, those are
prohibited in the EU I think. You'd have to take it apart to see, I
guess, some may have only screwed connections. No chocolate blocks in
the US that I've seen.
As far as the lightbulb not screwing in properly or damaging the
lampholder, that doesn't seem to be a problem, based on the customer
complaints I get (I work in engineering.) We do get the occasional
person who complains the bulbs burn out too rapidly and blames the
power, but we've never found a mains problem. Maybe they twist the
bulb too hard screwing it in and damage the air seal; at least that's
been my suspicion though I have no evidence. |

Or maybe not. I just looked at a German outlet. It is not polarized,
so you can insert any German lamp either way. So it shouldn't matter
with a US lamp either. |

Almost all the portable fixtures (that is, table and floor
lamps) I have purchased in the US in the last few years (or
for perhaps much longer) have had polarized plugs.

That's why I said "In EU countries with polarised mains supplies".
Germany and France (and others which use their mains plugs) don't.
(Incidently, unlike the German outlet, you can't plug in a French
plug either way around, but it isn't defined which pin in live and
neutral. In double outlets and 2-way adaptors, the two outlets are
usually hard-wired the opposite way round.)
