Retrofitting this downlight into an existing 50mm MR16 fitting will transform your lighting and save you money, ensuring that this replacement unit is beneficial on many levels; it uses less energy, requires zero maintenance and it transforms a dull and uninviting space into a contemporary and sleek environment. In addition to offering a wide range of colours – including the most subtle pastels – there is an option to choose pure white light for the moments when practicality is more important than atmosphere.
