PHughes,
As Brian noted, is looks like you are trying to find modules for the UK. Based on your description, and your previous posts, it sounds like you are looking for a Micro Module that is compatible with your Halogen lights.
As Brian requested, please provide a bit more information on the type of Halogen lighting you are using.
Also, the link you provided indicates that there is no neutral connection in your switchbox. Is this correct? If so, things will be a lot more difficult (micro modules require a neutral connection).
