Replace a GU10 Halogen with LED?

[Regular.Cyclist]

I moved into a new home in 2017 which had 45 halogen lamps, a mix between GU10 and MR16 and all 50w or 40w. There were 9 in the living room alone. 450w to light one flipping room!

All were quickly changed to 5w ‘cool white’ LEDs. One thing to be aware of on MR16 lamps are the drivers may be AC and cause flicker. If so they need to be replaced with DC drivers which ups the cost.

If the OP has all GU 10 lamps then these are 230v and have no separate driver.

Luckily I mainly use lamps, with energy efficient bulbs, in the main room. But bathroom and kitchen are infested by halogen GU10.
Oh they've just arrived...

Does anyone know if there's a dimmable version of the LED GU10?

If replacing MR16s can I just replace with a GU16 unit and then wire straight into the GU16, discarding the transformer box the MU16 used.

something like this as i need bathroom rated

MR16 were, are 12v rated.
GU10 are 230v rated
They have different bases to avoid confusion and potential "spontaneous loss of envelope integrity" and worse.

Philips do a " Expert Colour " GU10 with a CRI of 97 ( colour rendering index ) they cost around £12.
I have one fitted to flexible " child " part of a " Father and Child " style uplighter beside my chair. Excellent if you do a fair bit of reading or close work. The light quality is the same as the very expensive reading lights that are often advertised in the newspaper/ Radio Times etc

ok all done for the main house... nearly. I changed the ones in the bathroom (they were mr16 bulb) so went to screwfix and got LAP GU5.3 but they seem to flicker - so do i need to get an electrician to come and fit a transformer?

You need an LED compatible driver, not a transformer. They give out DC, not AC and are quick and easy to fit.

Yes, ditch the tranformers. The lights in your link are 204v.

the LED ones I linked, like most new LED ones, have integrated drivers

I was referring to the OP and their flickering MR 16 lamps.
