When the power requirement of the LED strip installation exceeds the allowable output of the LED controller you will need to use an LED amplifier / extender. An infinite number of amplifiers can be controlled from one controller.

LED amplifiers can be used to control single colour, dual colour, RGB, RGBW and RGB+CCT LED strip, the number of available channels will dictate how many colours can be extended.

The higher quality amplifiers will switch colours without a delay such as the LL-AMPLIFIER5 which switches at 10Mbps.

Amplifiers can be powered by the same LED driver that is powering the LED controller or a separate LED driver can be used. Drivers must be of the same voltage as the LED strip which they are operating.  The LL-AMPLIFIER5 allows you to operate different voltage LED strip than is wired to the main controller.  For instance the controller can be attached to a 12V driver and operate 12V LED strip, and the amplifier can be attached to a 24V driver and operate 24V LED strip.

You will need to ensure your LED controller is either common anode or common cathode and that the amplifier is of the same. The majority of LED controllers are Common anode, this is where the common circuit is positive (+).
