nicoskaralis:
Each segment of 3 LEDs has a current draw of 20mA, so I assume it has a maximum(?) draw of 2A (100 segments * 20mA = 2000mA = 2A)
Correct, but that is per colour, so the strip could draw 3*2Amp = 6Amp.
A 1Amp supply would only be able to do one colour at half brightness power.
The controller is probably programmed for these limitations.
