Hello.
The Ikea lights are not a bad budget solution. I find them to be a bit spotty in some installs.
I would recomend my own product in the power buys section, it costs a little more at £27 for the full kit (AVForums Price), but you get a much brighter spread of lights.
I will also be selling LED kits hopefully in a couple months, similar to the IKEA kits, but that comes with a remote, and allows you to change colours etc..
