Solution : Minimize your run length! LEDs have a minimum voltage requirement.
Tests : Remove sections of strip from the end of your run should improve both dimming and flickering. 3) Voltage dropĭiagnosis : Flickering across the entire strip that is accompanied with a significant decrease in brightness across the stripĬause : Excessive run length causing voltage drop leading to both dimming and flickering If you’re using a dimmable driver, make sure the dimmer switch you’re using is compatible. If you’re using a non-dimmable driver, note that any dimmer switches on the high voltage side are NOT compatible.
Solution : Make sure everything is compatible! If you’re using a dimmable driver, note that dimmers or controllers on the low voltage side are NOT compatible. Tests : Removing any dimmers or controllers from the circuit causes the flicker to stop. Read more about dimmer compatibility hereĭiagnosis : Flickering across entire strip that is affected by the level of dimming.Ĭause : Incompatible dimming protocols (eg PWM vs CCR or Magnetic vs Electronic) causing fluctuations in voltage and/or current. Advice on both available on our blog post here. Solution : Fix the connection! Check out our solderless connection troubleshooting tips or consider soldering. Tests : Moving the strip around in your solderless connector will change the amount of flicker or even temporarily stop it from occurring at all. Almost exclusively present in solderless connectors (not in soldered or spliced connections) Read more about connector troubleshooting hereĭiagnosis : Flicker begins (or significantly worsens) after a connection.Ĭause : A poor, inconsistent, or intermittent connection can cause flicker by alternately making and breaking the electrical circuit. Those reasons, ordered roughly in descending order of frequency, are poor connections, incompatible parts, voltage drop due to long runs, and defective or overloaded power sources.
Led light flicker how to#
Luckily for your client you’re an LED professional (you’ve read this very blog post) and you know how to solve LED flickering issues.įlickering is caused by a handful of different reasons, and once you’re aware of the causes it’s easy to identify and solve the issue. What should be a smooth and even glow looks like a busted neon sign. It’s the LED professional’s nightmare : You finish the install, turn on your strip lights, and encounter the dreaded LED light strip flicker.
