    Recessed Halogen Transformer Ceiling Light

    Evening guys, A friend of mine has had these halogen ceiling recessed lights for about 17 years. Anyone know where to obtain a new transformer from? Would they still be available? If not, alternative would be new LED fittings hopefully without transformers. Many thanks
