GTI,
If can identify as you claim the switch wires, this is what you need to do.
The in-coming and out going Blues(neutrals) terminated together (not the Blue Switch wire) to Blue terminal side of light.
The Blue switch wire(which should be sleeved Brown) to Brown terminal side of light.
All the Brown cables terminated together
all the earths terminated together to earth
and that should do the trick.
Remember to isolate electrics safely before carrying out any work.
Good Luck

So you have connected the three browns together with a connection block of some sort put the switch blue to new lamps brown and other two blues to new lamps blue with all earths together that should work.

But if you connect all blues together it will blow fuse as blue from switch is not neutral it is switched live.

Hello, please help this novice...

I'm trying to connect a NEXT Luna 5 light but cannot relate to the current posts solutions.

My ceiling rose circuit at present looks like this; (from left to right)

was blue, black red, red, red black, (was brown)

I thought I'd just need to connect the Earth wire along with the others, blue in where blue was and brown where the brown socket was previously. [b]Do I need to use the connector block supplied? If so, what goes where as there are only 6 holes and my ceiling rose above has 7 wires in total.

My fuse box keeps tripping as a result and I'm running out of ideas...please help, thank you in advance.

To Chrisg140 Ceiling rose normally 8 holes? 2 with switch wires, 3 with power, 3 neutral wires. Plus clamp for earths. Normal problem is mixing up switch wire and neutral wires both which may be black or blue with new colours. There should be a red or brown sleeve on switch wire but often missed or fallen off. Normally you need an extra connection to those supplied with lights for the live wires which do not connect to new lamp but link all lights in the house together. Also not a good idea to add question like this to existing post better to start a new one. It could really confuse GTi

Hi Eric,

Thanks for your reply. Unfortuantely, I'm still not there yet. I understand the switch (blue and brown) must not be clamped in the wrong holes. At present the ceiling rose looks like this:

brown, black red, red, red black, blue

earth on the new light is connected to other earth clamp

I've tried again this morning and it is still tripping the fuse. IS THE CONNECTOR BOX SUPPLIED A COMPULSORY COMPONENT?

On a standard ceiling rose forgetting about the earth it has three sets of connections.

A double called L this has the switch wire which is normally Black with a red sleeve on it plus the brown wire to your lamp.

In centre called Loop a triple connector which will have all the red wires and does not connect in any way to your lamp.

On other side another triple connector called N this should have two black wires plus the blue wire to your lamp.

This gives total of 3 reds and 3 blacks you only list 2 blacks?

The main problem with people trying to wire lamps is the rose does not only work the lamp you are working on but also supplies other lights with power. As a result we have three red wires which do not connect to the light fitting at all.

Second is of the three black wires one is live and should have a red sleeve and the other two are return and under no circumstances must the black with red sleeve be connected to the other blacks.

I will guess you have got the blacks mixed up? but since you are missing a black in your count you may have also not realised that you have three connections.

I have given detailed instructions on how to work out which wires are which on previous posts but until you have found all your wires there would be no point. I have put instructions on my web site which has www in front of log in name and is on talktalk.net but we are not allowed to give links. There are also projects on this forum which will help.

In view of the problems you seem to be having I would consider your best option is to get an electrician in to sort the problem.
