Here is mine in action. 24v weatherproof with repeaters to sync it all together. Just took some random photos while it was on colour splash tonight. By no means is this the range of what it can do, it gives a decent representation of what it looks like though.

Its 8m (26') between the walls but it lights the whole room. The strip is hidden in my shadow line, not sure what that is called elsewhere in the world, but basically a gap at the edges of the ceiling.

edit: I'm running about 45m (148') of LEDs here, using 4 x 200W power supplies, 3 repeaters, and 1 controller.
