so... build it your self.
Step 1: Buy Your Stuff
Here in Germany it's easy to buy them for example from ITEM, when you want to do that, wirte them a mail with your order.
And to put them on the wall you should buy also a cover profile:
You can buy the LED-Stripe nearly everywhere, I bought nearly 50m directly in China for 80€.
Step 2: Put It on the Wall
(I'm sorry but I can't find the fotos. When I'll find them I'll add them here)
Therefor you cut the cover profile into pieces and screw them on your wall.
Then you simply clinch the profile in.
Step 3: Solder Time
and .... done :-)
