You can avoid the visible flicker created by pulse width modulation by using an LED power supply that is specifically designed to work with dimmable LEDs. However, if not done correctly, it can cause dimmable led flicker and flashing led lights. Pulse width modulation (PWM) is a process that allows an LED to be dimmed by rapidly turning it on and off at a rate that is too fast for the human eye to see. In order for an installation to avoid LED dimmable light flickering and flashing, both the power supply and the bulbs must be able to communicate with one another to deliver the right amount of power. Just because an LED is dimmable, doesn’t mean it will work with every kind of dimming system out there. Be sure to use a dimmable power supply that is compatible with the LEDs you’re using. Use Dimmable Power Suppliesĭimmable LED lights flicker because you may not have the correct power going to the LED light. If it is an isolated light bulb or light fixture flashing then before going any deeper into why your dimmer lights flickering, swap the suspect fixture for one you know is working and see if you can isolate the problem down to a faulty product. If your dimmable LED light bulbs flickering then they could of course be faulty. Branded quality for good dimming with most dimmer switches. 100 Watt replacement 13.5 Watts (1600 lumens). Soft white 2700K all frosted glass A21 shaped E26 base. When shopping for LEDs, be sure to buy only dimmable light bulbs to avoid dimming led lights problems like led bulb strobing.Ī manufacturer of LED product and bulbs still give you the choice to create a dimmable LED lighting circuit or pay a little less and buy a product that isn’t dimmable. What is a dimmable light bulb? Dimmable light bulbs are designed to be compatible with a dimmer so the light output can be smoothly reduced as instructed. If you try and the product isn’t dimmable you could also cause buzzing LED lights. LED light bulb flickering can be the result of trying to dim a non dimmable blub.Įither inside the LED bulb or within the lighting setup, there are power supplies that power the LED light sources and when the current is reduced to dim them, these power supplies need to be able to translate the lower power into a reduced delivery of power acceptable to the light source. The LED isn’t DimmableĪ common reason of why do my dimmable lights flicker and LED bulbs flash when dimmed is that the LED itself isn’t actually dimmable. They will be able to spot any potential problems and fix them before they cause any damage. It’s always a good idea to have a professional check your wiring before you start using any new electrical products in your home. If there are any loose wires, they will need to be reconnected and/or tightened. Loose wiring is one of the most common problems we see.

When your led lights flash when turned on, flashing led lights are not only annoying and uncomfortable, but evidence that something is most certainly not quite right somewhere within the lighting circuit. Has the Dimmer Switch Been De-rated When Choosing? Have You Exceeded the Maximum Quantity of LEDs? Is the Dimmer Switch in Programming Mode?
