Shortening a light fixture with metal rod

[synesthesiac]

I've bought the Made.com Billie triple pendant light - this one: https://www.made.com/billie-triple-...YxH3n-3n2IipWzOK9gRoCjecQAvD_BwE&gclsrc=aw.ds

It comes with a ceiling rose and an attached rigid metal stem, which screws into the triple arm pictured. The whole thing weighs about 3.6kg (metal structure, glass shades).

It turns out the stem is too long for the height of my kitchen. Ideally I'd like to just replace the ceiling rose and stem with a shorter version, but I'm having trouble finding something that would do the job. A friend was going to wire it into the ceiling for me, so while they are competent at electrics, I don't think they'd have the tools or knowhow to cut the stem and cut a new screw thread into it.

Has anyone done anything similar with this model?

Could anyone suggest my best options with this problem - where I might find a shorter stem (with screw thread that would fit the light) and corresponding ceiling rose - or whether it would be safe, with this weight, to hang the light from a fresh ceiling rose without the metal stem? I live in a ground floor flat so I can't get above my kitchen ceiling to look at what's in between the 1st floor floorboards and my ceiling...

Thanks very much in advance.

Depending on the size and type of thread inthe fitting you might find what you need here . https://www.lampsandlights.co.uk/lighting-components.php

The maker/seller might be able to tell you the specs of the thread. Shortening the tube is no problem - all you need is a hacksaw and a flat and rat-tail file to clean up the end.

If you can't buy a suitable tube then look for a local model engineering club, or a group running a miniature railway etc, as they'll almost certainly have someone who would cut a thread on it for a nominal fee/donation.

While it's dismantled think about rewiring it to supply the outer 2 lamp holders separately from the centre one, as that would give you the option of 1, 2 or 3 bulbs on.

I had a similar light for our dining room which we swap round at Christmas as the Fire is then used in Winter. I shortened it with an angle grinder and my Father inlaw rethreaded the top.

Depends on the size you need but taps and dies are handy to have
Practice on scrap first

lighting threads nowadays tend to be 10mm, 13mm and 1/2 inch, but i think the pitch is different to most dies you see for sale.

It's a thin-walled tube....

Mine was quite a thickish Steel rod/tube BAS, thick enough to have a thread. Hence why I used the small disc to cut it.

Can't help thinking that a hacksaw, or even a junior one, would have made a neater job.

Then end had to be threaded after it was cut - which took about three seconds as opposed to 3 minutes plus sandpaper to finish off
