Weird the lights are only about 12 months old I would have thought the transformer would have been good to go
The fitting would have been 'made to a price' (like everything else these days) they wouldn't waste money making it future-proof.
so do I just replace the inside of the light fitting with say some thing like Spectrum 18W LED Driver Transformer for G4, MR11, MR16 LED Light Bulb Lamps and 12v Strip Lighting: Amazon.co.uk: Lighting
They should do... none available from local suppliers?
