This expansion plate is specifically designed to fit the Martec 12w Genesis LED downlight range.
It has an outer diameter of 140mm meaning that you can place it over an existing hole up to about 135mm.
This allows for a clean and tidy fit so you can change your old incandescent downlights to new energy saving LED downlights.
