Which ambient light system do you use?

Only the first LED (nearest Arduino Uno connected USB) lights up and cycles through but it isn't controllable from the command line. Sometimes the 2nd, 3rd & 4th LEDs light up too, less often more random LED light will light up along the strip but only faintly and don't cycle. Only the LED nearest the Arduino lights up properly and cycles.

I'm confident in the power adapter, less so the connections to it. When I first plug in the strip all of the LEDs light up for a fraction of a second.

If anyone could point me in the right direction I'd really appreciate is, is the strip a dud or is it a power/ grounding issue?

Check the connection of the led stripe. I have a stripe with the lpd8806 controller and although it was nice that the manufacturer soldered a cable with a plug to the end, he unfortunately soldered it to the output. That was why my leds were behaving oddly at first. So my best guess is check if you connected the arduino to the input of the stripe. I dont know about the WS2801 but with the lpd8806 it is +5V and GND for power and ground and DI (data input) and CLKI (clock input). Also the Arduino and the led stripe should have the same ground. This ensures there are no differences in potential.
