    Hi. Just wondering if anyone can please help with regards to fitting an LED bathroom light. I've attached a photo of the existing light fitting and wiring as well as photos of the new LED light. I'm very much a beginner with regards to electrics and the fact there's so many wires in the existing fitting and the new one seems to only be able to accommodate 3 is throwing me off completely. Please can anyone advise the correct way to wire this LED light using the existing wiring?
    Thanks
    Tony

    You will need to accommodate some cable connectors ,such as wago's within the base of the light fitting. Is there space to do it ?
    The terminal block on the fitting looks as though it doesn't have enough ports to acommodate all the conductors ,and needs a seperate connector block for All the loop permanent lives.

    The Reds are the Lives - what we call the Lines - one from the supply, one to the switch and the rest to other circuits. These must all be connected together but to nothing else.

    The Blacks and Blue are the Neutrals - one Black is the supply and the rest to other circuits. The Blue (not the one to the light) would appear to go to the switch for some purpose which is not usual. The Neutral for your light

    The Yellow is the Switched Live back from the switch. The Live for your light when switched on.

    The Earth wires out of my snip are from all the cables and must be connected together. The Earth for your light.


    I would suggest you put each group in a connector block with separate wires to the light L, N & E.
    Will there be room above the new light?

    Thanks for the replies, very helpful. I was just wondering on the photo of the connector on the LED light you'll notice there's three holes for each of the live, neutral and earth. Can I insert a wire in each of these instead of using connector blocks before running a single wire to each of them on the connector?
    Also for the earth is that just a case if unscrewing the green and yellow earth wire and wiring that straight into the earth on the connector on the LED light?

    Regarding having space for connectors there isn't space above the fitting but potentially is space in the fitting around where the connector is, the only issue with that is fitting all the wires through the hole in the base of the LED light, which isn't very large.

    Don't follow you regarding space in the fitting for extra connector blocks/hole in the fitting. More pics of the entire fitting may clarify ?
    Although the terminal block of fitting has 3 ports ,you have more than 3 wires to fit into the neutral and earth terminals. 4 of each in fact.
    Do you have access above the ceiling ?
    You could make all connections there in a junction box and from it one 3 core cable to the fitting.

    Sorry I've not got back before now. I've bought a different light now that doesn't require an earth and has some space that should be big enough for some connector blocks. I've also bought a wago connector kit and following advice given in another thread here https://www.diynot.com/diy/threads/ceiling-rose-to-wago-connectors.485378/ I know what connectors I'll need to use. Just one question I have is do I need to use something like a wagobox to contain the connectors or will they be ok just in the space between the light and ceiling?

    If your new fitting is double insulated ,you could terminate all the connections in a wago box ,and from the wago box connect a suitable cable down into the light fitting. Wago box located in ceiling space above the light fitting. Show us a pic of new fitting ,if it's all plastic you may be able to make the connections within its base.

    Thanks Ok so where in that other thread they were using 224-101 and 224-102 for the switched live and neutrals is it advisable to use a 222-412 and 222-413 so they can be placed in a junction box like this https://www.screwfix.com/p/wago-junction-box/7355f with a 2 core cable then connecting into the vacant slot on each and coming out of the junction box to the light?
    Also how is it best to terminate the earth since it won't be required? Would a 222-412 be ok for that with the earth going into it and nothing else connected to it?

    None of those wagos have enough ports to accommodate the number of conductors ,except the two switched lives.
    For example you have 5 neutrals,4 live,and 4 earth earth's. You can't connect 4 conductors in a wago with only 2 or three ports.
    If you intend to put the junction box in the loft ,you could Just use a conventional round junction box if you wished.

    I have some 222-415 connectors too so I could use those right?
    I don't think it's easily accessible from my loft unfortunately because I have a gravity fed water system with a big tank above my bathroom so any junction box would need to be pushed through the ceiling. It would be great if I didn't need to use a junction box mind so that's ok as long as I can house the connectors in the light fitting and it's plastic right?

    Yes ,you can use 5 way wagos for upto 5 conductors. And the junction box can be pushed up into the loft from below. Without sight of the space within the fitting ,who knows if there is enough space ,or if it's suitable to make all connections there. Time will tell.

    Cheers mate. I appreciate all the advice. I'll send you a photo of the light when it arrives along with some wago connectors sitting in that space to give some idea of if it will work or not.

    I've just got the light and there's definitely not enough space so will need to get a junction box. At least I know I definitely need one now. I've attached a photo of the connector set I've got. So if I use the 222 series connectors I'll need 3 of the 222-415 connectors and 1 of the 222-412 connectors right? Will they all fit in this junction box? I guess there will need to be room for 2 of the 222-415 down one side. Also are the 222 connectors a better option than the 773 connectors? The 773 connectors are definitely a fair bit smaller but I guess as long as there's room in the junction box to use the 222 connectors then it doesn't matter. https://www.screwfix.com/p/wago-jun...NrluYhPebIpb_UgbOZxoC4XQQAvD_BwE&gclsrc=aw.ds

    Will be a bit of a squeeze with 3 X 222
    The 773 s would be easier.
    Or two X 773 ,one 222 4way and one 222 two way.
