The Fibaro Bypass 2 is a device designed to work with the Fibaro Dimmer 2. The Bypass 2 is to be used with LED bulbs (such as a single 0.5 Watt LED) or energy saving compact fluorescent lamps. The Bypass 2 prevents LEDs from flickering and turned off compact fluorescent lamps from glowing.
In a 2-wire connection, the Fibaro Bypass 2 reduces the minimum power of load required by the Dimmer for correct operation. The Bypass 2 provides powering of the Dimmer 2 in case of controlling low loads.
