I have a couple of g10 downlighters in the ensuite. Can I just swap these for g10 leds? Thanks.
Think you might need to change the transformers as well. Well that’s what I did and works perfectly well.
Someone told me the transformers are built in. Is that wrong?
If the Halogens and LED are both mains 220VAC then yes, just a straight swap.
Is it a normal on/off switch or a dimmer. If a dimmer then (a) you will need to make sure you buy dimmable LEDs and (b) you may need to change the dimmer to one that is compatible with LEDs. I always advise to just try your existing dimmer first rather than rushing out to buy a new one. But if a normal switch then nothing else to do other than swap the bulbs over.
Hi Nigel. It’s a normal on and off. No dimmer involved at all.
And to your knowledge are the halogens just normal mains 220v types, not low voltage with an external transformer.
If normal mains then just swap out with LEDs.
GU10’s by their very nature are mains fed.
Nigel has it.
If the lamps are bayonet fitting (push and twist) They are GU10 mains. If they are two pin push fit, they will be 12 volt and have an associated transformer.
If you have the 12 volt type, suggestion would be to replace the whole fitting for the GU10 type, removing the need for the transformer, which will most likely need replacing with an LED driver if you keep the 12 volt fitting.
I bought these from Amazon:
We have MR16 (transformer type) downlighters on the landing, but as either the bulb or transformer fails, I replace it with one of the above. It's a straight swap: just attach to the 240v input via the junction box used for the transformer. You don't need to change the fitting.
This seems to be getting over-complicated.
Standard GU10 downlighter bulbs are mains powered.
GU10 replacement LEDs are also mains powered.
Simple swap. Full stop. My recommendation would be to err on the side of higher light output (wattage equivalent). Also, watch for the colour temperature - 2700-3000k for a warm white similar to halogen; if you want to go "modern", 6500k is very white white.
Ok so I’m happy my gu10s are a bayonet fitting and a straight swap for led. The best bulb in the extractor fan has blown and this one is a MR16 12v 35w 300lm so I guess I will have to do a straight swap for another halogen on this one.
Doesn’t seem like you can get them any more :-( not sure what to do.
Take the bulb to your local electrical merchants (not diy shop). They will soon tell you what bulb if any you can use instead
Won't these do?
Got some from bunnings in the end
Bought these recently, still £9.90...
Another year on and GU10 LEDs are even cheaper!
I’ve got so many of them. Been swapping them with colleagues for their halogen ones. I haven’t come across a LED yet that ready does it for me. Ok, besides the Philips Hue bulbs. Colour temperatures are off, the beam is too narrow, the light roll off is too harsh. Just to name a few of my annoyances
I don't typically fit GU10 or MR16 lamps in luminaires cans for my clients, but instead the sealed unit fittings manufactured by the likes of JCC, Collingwood, Aurora etc. I'm told by some colleagues however, that the design, output of the latest LED lamps have improved in leaps & bounds. I have some old generation LED lamps in my own house, and are quite satisfied with them. I certainly would not go back to using halogen, simply because they are inefficient and not cost effective, especially in a house populated by teenagers!
Halogen GU10s are a good source of heat in the winter...
Have you had many problems with JCC downlights?
There was a bit of an issue with the FGLED6's, my wholesaler won't stock them now. The Hybrid 7's had a technical issue at launch. Otherwise its been hunky dory
I haven't had many issues with them but I know some electricians who have. I've started using KSR recently.
I've just about managed to persuade a Halogen GU10 loving client to change to integral LEDs...
A testament to how rubbish they are at converting electricity into light
Yes exactly, it's ridiculous how hot they get!
I prefer the warm ambiance of my Plasma TV, stick this on and you can't tell it's not real

You don't get the same realistic warmth with an LCD screen
Haha, very true! One of the many reasons to love plasma TV's, although not particularly efficient...
Oh I wouldn’t like those. I much prefer something where I can Philips Hue bulbs in and control the lighting properly throughout the area.
Arrrgh bit old fashioned me, can't see why you want to turn your lights on when down the pub. Its never put off billy burglar. Just use the good old light switch.
If you do want to go down that road, there's something some much better and properly expensive
Oh not just about switching them on remotely. It’s about the ability to create scenes, but foremost quality light. Like with many things light is make makes it happen, yet most of use are happy to put the cheapest bulbs in our homes. Always surprised me.
I wired a new house a few years ago which was completely home automated, I never saw the appeal of it myself but it was quite impressive, I guess...
Guess whatever floats your boat, and of course it must be somehow connected to WiFi, just to have the latest whatever.
