LED flickering is one of the most common issues homeowners encounter after switching from older bulb types. It is almost always tied to compatibility rather than a fault in the bulb itself. Here is what actually causes it, from the licensed electricians at EZSMART, serving Toronto and the GTA.
Most flickering issues are resolved by matching the dimmer to the LED bulbs, using quality bulbs from reputable brands like Philips, and ensuring the dimmer is LED-compatible. Widespread or worsening flicker should be diagnosed by a licensed electrician in accordance with Electrical Safety Authority standards.
Do all LED bulbs need special dimmers?
Only if you plan to dim them. Non-dimmed LEDs work with standard on-off switches, though even standard switches occasionally cause flicker with lower-quality bulbs.
Why does my LED bulb flicker at very low dim levels?
Some LED-dimmer combinations struggle at the lowest dim levels. Raising the minimum dim level often solves this.
Can flickering damage LED bulbs?
Persistent flicker can shorten a bulb\’s lifespan, particularly if it is caused by an incompatible dimmer.
