Dimmer switch compatibility: avoiding flickering and buzzing

Frequently Asked Questions

Flickering or buzzing often occurs when the dimmer switch isnt compatible with the LED lights. This is common in Singapore homes using older dimmer models. LEDs require specific dimming technology, so ensure your dimmer is LED-compatible.
Look for dimmer switches specifically labeled as LED-compatible or designed for LEDs. These dimmers use technology that better regulates the lower power requirements of LEDs, preventing flickering and buzzing. Check the product specifications and compatibility lists.
Common types include rotary, slide, and touch dimmers. For LEDs, electronic low voltage (ELV) dimmers or those specifically designed for LED compatibility are generally the best choice. Leading-edge and trailing-edge dimmers are also options, with trailing-edge often preferred for smoother dimming with LEDs.
Not always. While the dimmer might be LED-compatible, the specific LED bulb may not be compatible with that particular dimmer model. Check the dimmers compatibility list for approved bulb models, or choose bulbs that are explicitly listed as dimmable and compatible with a wide range of dimmers.
First, check the wattage rating of the dimmer switch and ensure its appropriate for the LED lights youre using. If the wattage is correct, try replacing the LED bulbs with models known to be compatible with your dimmer. If the problem persists, consider replacing the dimmer switch with a newer, LED-specific model.
