Seanie_230:
Does the Rania just replace a UK switch no external power supply needed?
Yes you just remove your existing light switch and join the rania to the existing wiring. It works no problem with a beo4 (LIGHT) or a beo 5 if you get it put on by your dealer.
Using the coloured (green tellow red blue) you have preset levels of light. Using the scroll up/down you can turn the lights on and off or find a level of light you want.
I have two in seperate rooms and I like them. They are a better product than the LC2
