The dimmers provide a discreet way to control LED strips. Choose between 8 brightness levels, turn the lamps on or off, or select a dynamic mode for extra effect. Installation is simple, just connect it between the driver and the strip. Use it with LED strips that use a 12V-24V power supply, such as ABI single-channel LED strip lighting kits.
