If its on a budget, then something simple like
THIS will do the job.
There are restrictions with this kit, ie. 60-300w incandescent and 12v low voltage only.
X10 is pretty much introductory level, and fairly simple to work with.
If budget it not so much of an option, then there are other alternatives.
If this is going to be the only automated lighting you will have, then X10 will do fine.
If you are planning on getting more into it, there are lots of systems you could install that are more versatile.
One thing to remember with the X10 kit. That unit should be wall mounted, so you will
need to be able to hide it local to the displays. You will also need one of
THESE.
The transceiver accepts your remote signal, and sends the appropriate X10 signal
onto your mains wiring.
You will also need a remote. Something like
THIS will do fine.
