Lumos!
I have recently installed this remote & sound kit at a steady pace over a few evenings whilst drinking a cuppa and of course watching some Potter on the TV. Whilst it was definitely fiddly and I uttered more than a few choice words, the end result is truly spectacular. Having the remote and the soundcard is the absolute icing on that cake as well - I wasn't expecting to be able to turn the individual sections on and off nor to be able to dim the lights either. Photos don't do it justice. I have nothing but the highest levels of praise for this light kit and I am seriously considering buying a Game of Bricks kit to replace an inferior set I used with my Rivendell set.
I also have to pass on thanks and mention the customer support - first rate, accessible and convenient too.
