This LED dimmer is practical and easy to install on a cord, allowing you to adjust the brightness of your dimmable LED lights with a power of 1 to 60W. This rotary dimmer for LEDs can be used with almost all dimmable LED bulbs at 220V/230V. Our dimmer adjusts brightness continuously without annoying noise or buzzing. The LED dimmer (cord dimmer, cable dimmer) features a rotary knob for continuous light control and on/off switching. The knob clicks when you turn it on and off. With our cord dimmer, you can easily dim the brightness of any non-fixed lamp, provided the LED bulbs used are dimmable. Adjust the light in your living room to suit your mood. Important Note: This cord dimmer is not suitable for traditional halogen, low-energy, or incandescent bulbs, transformers, devices, or LED lamps with electronic ballasts.
