Though I'm not sure this is an American forum I hope some USA DIYers are able to help me. I am a Dutch lamp designer and I just designed a (ceiling mounted) lampshade. In Europe we use E27 lampholders like these. You can pick them up at any DIY store, and everyone knows how to use them:

For my new design a pendule like this is necessary. I want to sell my lamps in the US. Do you use a similar system? What do you commonly use to mount a ceiling lamp?

well, not really sure what she is looking for.

I do not know what the unit she linked is attached to. That would help. If it is a single unit by itself, most fixtures in the US mount to a round steel box like this:



If it is a heavy fixture, the box must be rated for the load. Most fixtures use , more or less, a decorative plate the wire passes through instead of that screw base thing in the link.

If the fixtures are intended to be sold commercially, she also needs to look into UL listing as well.

Yeah, usually a metal ceiling box & then the light bracket attaches to the box
Threaded rod goes thru the middle
Light housing goes up & then glass...then a "finail" (?) screws onto the rod that goes thru the glass holds it all together

The other end

Thanks so much for your replies:thumbup:! Unfortunately I am interested in the other end of the wire!!! My design is very easy in use. You don't need to dismantle wiring from your ceiling. People only need to buy the shade and can use it on their own (already) hanging wire. All I need to know is how you attach the fitting (that's what we call it in Holland) to the lampshade.

This image shows how the fitting is screwed into a hole in the lampshade. I found this on the (American) Ikea website. Is this a standard way for hanging a lampshade? What is the circumference?

All (as far as I know) of our ceiling light fixtures are hard wired to wires in the ceiling.

So the fixtures comes with wiring that you twist to the existing house wires & cap them
A canopy then covers the wire junction area - this is a junction box mounted in the ceiling

Wow, great picture! This looks very sturdy to me! So you've never used something similar to the Ikea thing? Here it's used for light (light as in light weight) lamps and shades. Your picture shows an end part (I mean the white plastic part with the screw thread). Do you think it's possible to connect it to my shade? Does it come with a ring? Do you know (or someone else) what the circumference of this part is? (I know, questions, questions...It would be so much easier if I could just get my hands on one and try it out!:sweatdrop:)

That is where the light bulb screws in
Every fixture is different
But you remove the old fixture & wire up the new fixture
The lights/ceiling setup we currently have (that I have seen) are not setup to just swap out the shade

There are some setups - like over a kitchen counter - that are made tohave hanging lights
But usually you buy the entire setup & wire it up
In a lot of cases the Mfg makes different hanging lights that then can be attached using the initial setup

I haven't bought a single pendant lite myself....so no direct experience

One Mfg that uses a standard plug for their product (low voltage)

Thanks for your help, appreciate it very much. Maybe I can order a fixture from the site! I have to see it up close to make the needed adjustments to my design.

ceiling lamp

I dont know to much of construction work, but I would love to see your work. I am from the netherlands, grew up in The Hague. I live here in the U.S. for 5 years already.

What I only know is we have a different wall plugs, that is the only thing I can tell you, haha I know you must know that.

Mainly I wanted to reply because you are Dutch and it is good to see Dutch entrepreneurs.

Greetings your friend Sarah

As for the guys they did hit the nail right on the spot however let me add one more step as you are aware that the North Américiane system typically 120 volts line to netural not the same as our 240 volts is and the colour format is differnt as well the North Américianie colour format is.,,

Black - Active or Line
White - Netural
Green or bare copper - Earth or grounding.

And the bulb base is pretty simauir to our E27 base { there will be a little variation between the E26 and E27 base size so just watch out on that one. }

Merci,
Marc
