Anything below 100 Hz is usually safe, while anything above 120 Hz can cause discomfort. People with photosensitive epilepsy can experience seizures triggered by flashing lights.
Why does dimmable light flash or flicker?
If you’ve ever used dimmable lights, you may have noticed that they sometimes flicker or flash. This is really frustrating and distracting, but it’s also important to understand why it happens so you can prevent it from happening or find a solution to the problem.
What causes dimmable lights to flicker or flash?
There are a few reasons why dimmable lights can flicker or flash.
Low-quality dimmer switch:
If you have a low-quality or incompatible dimmer switch, it may not handle the load of the lights, causing all bulbs to be compatible with all dimmer switches. If you’re using a bulb that’s not designed to work with your dimmer switch, it can cause flickering or flashing.
Electrical interference:
Interference from other devices in your home or nearby can also cause dimmable lights to flicker or flash. This can include things like motors, refrigerators, and other electronic devices.
Loose connections:
If the connections between the dimmer switch and the lights are loose, it can cause the lights to flicker or flash. This can be caused by a variety of factors, including poor installation or wear and tear over time.
Compatibility issues:
LED bulbs are not always compatible with all dimmer switches. That is why Dimmable LED flash can occur. Using a dimmer switch that is not compatible with the bulbs can cause flickering or flashing.
Overloaded circuit:
If there are too many lights or appliances on the same circuit, it can cause voltage fluctuations that can lead to LED flickering or flashing.
Voltage fluctuations:
If there are sudden changes in voltage levels can cause LED lights to flicker or flash. This is because of electrical issues in the home or fluctuations in the power grid.
Poor quality bulbs:
Poor quality LED bulbs are usually not able to handle the electrical current thus leading to flickering or flashing.
Faulty wiring:
Faulty wiring in the home or in the lighting fixture itself can cause voltage fluctuations. This can further lead to LED flickering or flashing.
Environmental factors:
There are certain environmental factors like temperature changes or exposure to moisture that cause LED lights to flicker or flash.
