Apologies for bumping an old thread if it's against the rules. I have the same light fittings and wanted to ask for some more details on changing the fitting. There are metal prongs in the black connector as shown in the attached image. How do I go about finding a new fitting that connects in the same way? I want to replace the light with brighter ones - is there a limit to the wattage of the new lights?

Can't edit the OP but this post was moved from http://www.ultimatehandyman.co.uk/forum1/help-changing-recessed-spotlights-completely-befuddled-t95559.html

For context, I'm trying to change the recessed spotlights in my flat but they don't look like normal bulbs. The fitting has a black wire connector and clips in to a black wire coming from the ceiling. The text on the side of the fitting says 'MR16-7W 4000K'.

Is there a transformer in the ceiling? Can I take it all out and replace with a fitting that will take normal light bulbs?

it will have a power supply as it a ccfl (Cold-cathode fluorescent lamp) I cant quite make it out but I think its a MR 16

iirc ccfl are high voltage

edit. if you want to replace them with leds you will need to rewire

Change the whole fitting, that way you can have what ever you like

You take the old fitting out, measure the size of the hole left and install new lights that fit the size of the hole.
You get new fittings almost any diy shop, but you could start at screwfix

What you appear to have is a dedicated fitting. The idea was that you can only replace it with what is already there (CFL lamp) there was also a similar idea with pendant lamp holders (The ones that hang down and you put your choice of lamp shade on) there were some that had 3 "holes" so you could only use a "special" CFL lamp. People did the obvious, took the lamp holder down and put up a normal one.
You need to do the same.

Do I need to replace the transformer to install LEDs?

Is there only one transformer for all the lights. Any markings on the transformer?

Since a cold cathode lamp no idea of voltage or any other details of the power supply, MR16 means it has a multifaceted reflector and is 16/8" across, but 12 volt (extra low voltage) normally G5.3 base, and 230 volt (low voltage) normally GU10 base, use the same name.

A 12 volt LED MR16 will work from a 12 volt transformer, but will not work from most electronic transformers.

But a cold cathode lamp may have a ballast rather than a transformer, so you need to find it and read what it says on the unit. Building regulations at one point required a set percentage of lamps in a new build to be of a type with less heat output, we had as already said the BA22d fitting with three slots instead of two, and the GU10L1 fitting which was same as the GU10 but with a dimple in middle so standard tungsten bulbs would not fit, the problem was neither would most LED bulbs.

I think the Part L1 building regulations have changed, as not seen the special holders that would not take non energy saving for some time, but I can't find any info on what you have, so you will likely need to find the power supply and take a picture of the label for anyone to know what it is.

I am reasonable sure they are not high voltage, I suspect well under 1000 volt, we are not in USA, in the UK up to 50 volt is extra low voltage, the site 110 volt supplies (55-0-55) is reduced low voltage, and normal house hold supply is low voltage. There are some high voltage supplies to neon lights, but sure not used in domestic homes?

No using the GU10 base you can get 230 volt LED lamps.

Is it a transformer, or a ballast?
