This problem occurs when the power consumption of the circuit is less than 15 W. This may be caused by an insufficient number of devices or low power of the devices used. It is important to note that for the dimmer to operate effectively, a minimum load of at least 25 W is required. If power consumption is below this threshold, the dimmer may operate unstable or not turn on at all.

To solve this problem, it is recommended to install an LED adapter. LED adapters are designed to increase the load and ensure stable operation of the dimmer with low power consumption. They allow you to maintain the minimum power required to operate the dimmer, even when using low-power devices.

Thus, installing an LED adapter will help avoid problems with the operation of the dimmer and provide stable lighting or brightness control in your circuit.
