The LED strip's amplifier (A) requirement depends on the wattage and operating voltage. You can find the amps(A) value by using this formula: (A) = Power (W) / Voltage (V). So, if your LED strip is 12V and consumes 24 watts, the amplifier requirement is 24W / 12V = 2A. You must use a driver that can provide this amount of current for optimal performance.
