Dec 9, 2018 at 12:12 comment added Russell McMahon A "Mickey Mouse" 1st try: Place one or more suitably current rated diodes in series with the strips. Using eg 3 x silicon diodes in series (1N400x will probably be OK) will drop around 2V before substantial current flows. If this "almost works" try either a 4th diode in series or a resistor in parallel with the strips to conduct some of the controller current. The LEDs need non zero voltage to light but the resistor will draw current at any voltage. The diodes will reduce the maximum current that the LED strips will 'see' and so MAY reduce max brightness slightly.
