Shortening a Ceiling Light Cable?

Take off shade. Tie the cable in a simple knot near the bulb end. Bingo! You've shortened the cable.

Oh dear!

You'll be trying to tell me next that a 90 degree bend in a cable is dangerous too. :rotfl:

It certainly is if in doing so you've exceeded the MBR of the cable.

Solid copper is one thing, lighting flex is another... Lighting flex happens to be made of multistranded copper *so it can be flexed*.

Cheers to you too!

That's a different question entirely...
How do you know it's a 'modern' cable? It could be 40 years old, braided, rotten...and how do you define 'loose'?
You are making too many assumptions..

RTFQ. The OP said "It's a standard round plastic ceiling light with a white cable down to the bulb/shade."

Have you ever looked inside a (reasonably modern) ceiling rose? How is the cable supported?

If you take the time to look, the live/neutral wires are wrapped round a plastic lug before the wire ends in a brass terminal block.

The radius of curvature of the wire round that lug, which is supporting the weight of the lamp, is a bit smaller than you'd achieve by any realistic knot in the complete cable.

So please don't go trying to tell me that knotting a bit of lighting flex is a hazard. It's may not be 'best practices', it certainly isn't pretty, but it's not 'hazardous'.

Flex is not cable. But there are many types of cable and cable does not have to have copper core(s). I was specifically responding to your use of the word cable. Slightly off topic I would agree.
