Ced To Led Conversion - Rewiring The Starter And Ballast
Hi Guys,
I am attempting to convert the CED ligth fitting into LED. The fitting is round bathroom fitting with 4 pin ced light shaped kind of like pretzel, the fitting has starter and ballast.
It has 3 wires coming from the socket, blue, yellow/green and brown. The blue is connected to the unit in the middle and from it I have 3 more wires: yellow and white which go to and back from a starter in a loop and pink which goes to ballast. The brown wire from the socket is also connected to the ballast. The last yellow/green wire from the socket is simply screwed on the the metal base of the ballast.
I need to get rid of the starter - so I am thinking i need to cut it out and connect the yellow and white wire to close the loop.
I am also thinking that i need to connect the pink and brown wire coming in and out of the ballast.
But what do I do with the yellow/green wire from the socket that is not really connected to anything?
I have been looking for an instruction video but most are for the tube or recessed ced conversion and none have the wires coloured in the same way and none have the yellow/green wire that is not attached to anything.
I have been struggling without the bathroom light for a few weeks now and I would be eternally grateful for any kind of instruction!

Not heard of CED. A quick websearch seems to imply it is a particular company ?
Normal mains colour coding is that blue is neural, yellow/green is earth, brown, due to it's mud coloured quality was wisely chosen to be live.
Light fittings usually have a switched live also, coming back from the light switch. Live supplies can continue to the next light fitting on that floor, but it sounds as if you have fewer wires than that.
My suggestion is to investigate what is on each wire. Any live or switched live should be easily identifiable. And then connect according to the LED light instructions. If it isn't obvious, take the hit of getting an electrician in to do what should be a very quick job.

Hi Old_Geezer :-) thank you! yes, you are right - it seems to be company name. The light bulb I am trying to get rid of is Compact Fluorescent DD Lamp 4 pin 28 watt Daylight 6400k, trying to replace with MiniSun 12w LED GR10q 4 Pin Retro Fit Bulb. Yes, it looks like the blue s neutral, yellow/green is earth and brown is live. I kind of know what to do with blue and brown but what do i do with the yellow/green? Thx, Anna
If any of the casing it metal it will need to be connected to it somehow, top protect those who touch the casing. But if the casing is one of those "double insulated" types, all plastic, not metal, no place to connect then you need to leave the wire unconnected, but terminated/covered in insulation to avoid it touching anything. Not uncommon to bend it through 180º and tape it to itself. Or maybe connect it to a small single terminal strip and cover it with insulation.
In fairness I do DIY electrics but you may wish to wait for a professional electrician to detail best practice.
