Changing halogen downlights to LED - GU10 or GU5.3?

[lecky_bob]

I have 10+ halogen downlights in the house. They are 12v GU5.3 (MR16) with transformers. They have been in over 20 years and various parts are looking scruffy and even perishing, so I am going to change over to LED while renovating.

Are there any technical or safety considerations in going to 240v GU10 LEDs versus 12v GU5.3 LEDs?
If I change to GU10 I just need holders and bulbs, but if I stick with GU5.3 I will need bulbs and new transformers.

Might as well go GU10? Any other considerations?

GU 10s or maybe integrated fitiings like the JCC V50. Saves buying separate drivers.

You might need to consider earthing the existing fittings if upgrading to 230v GU10.
The GU10 lamp holders might be class 2 rated but the lamps aren't.

That's a good point, but having done some research there seems to be a lot of mixed opinion on exactly what should be done? It's left me unsure.

The units I have ordered say they are Class II and the lamp holders are double-insulated. The instructions that come with them specifically say 'do not earth'.

So, given I am changing the actual fittings and I am using double insulated ceramic lamp holders, I am ok? Or not?

That should be fine if the fittings are class 2.
I thought from original post it sounded like you were leaving original fittings and upgrading to 230v.
Bit of a minefield as some are class 3 and some are not and have an earth terminal for that reason.

Thanks for the update. In fact I was thinking of leaving the original units in so you were right! However with these newer GU10 units they are easier and neater to install and maintain so I went for replacement. I always hated those damned clips!!
