Looking at changing our lounge light. Came to take off the old light but finding it impossible to untighten the old bolts so will have to cut wires. Just want some heads up on the following before I do the following...

Turn off electricity
Cut/strip wires
Find which wires link up to the switch using multimeter
Wire up using the attached wiring pic.

Cheers

Connect the new light to the same two wires as the old light- the brown and blue connected to the bulb in your diagram. Leave all the rest of the wires alone. If it was working fine before there is no reason to alter any of the other wiring.

 

The wires coming out of your old fixture are just the fixture wires. They are thin, probably 18 gauge. They should be connected to your house wiring up above somewhere, hopefully in an electrical box. You'll need to find those house wires to connect your new fixture to. I wouldn't feel comfortable cutting those wires and connecting to those.

 

You should put non-US in your user bio. Things are done a little differently in the UK from here.

 

The connectors and the colours may be different but you still only need to deal with the two wires connected to the current light.
In your diagram your light has a line(brown) and a neutral(blue). Your new fixture should have the same line and neutral wires and you connect them to the exact same spot as the old light.
All the rest of the wires in the junction box stay where they are.

 

Managed to sort it. Zorft had the answer 👍
