LED Light Flicker Meter

Use Cases

Eye-Strain

Avoid eye-strain caused by flickering LED lights.
Measure your LED lights and screens to find out what causes the problems.

LED Lightning

Measure your LED lights or the lights in the store before you buy them to find out what lights are flickering a lot and whats light are shining steadily.

Headache

An headache can ruin any day. Find out potential causes by measuring the light sources and screens around you. A headache can be triggered by a constant flickering LED light or screen in combination with something else, such as a poor nights sleep.

The app measures flickering of lights that are flickering/blinking so quickly so that we cannot usually see it with our eyes. But it can still have a negative affect on us - eye strain, headaches, migraines and even epilepsy seizures are reported as consequences of flickering lights. With this app you can measure if your LED lamps, LED bulbs or fluorescent tube lights are flickering and how much.

How to Use the App?
Place the phone in a position so that the camera is facing a surface, such as a white paper or an evenly colored wall or a floor, that is lighten by the light source you want to measure the flickering from. It is important to let the phone stand still during the measurements as movement can cause the meter to measure a too high flickering value.

What is a Flickering Percentage?
The percentage flickering is the app's estimation of the difference between the maximum and minimum light output from a light source. A flickering measurement value of 25% means that the minimum light varies between 75% and 100% light output. A light that switches off completely in each cycle will have a flickering measurement of nearly 100%. A light that does not vary in light output will have a flickering measurement of nearly 0%.

How Accurate are the Measurements?
As long as the phone during measurements is standing still, without any movements and are directed towards an even surface, the accuracy seems to be within plus/minus five percentage points under normal circumstances on most devices.

What our users are saying

Very useful for detecting flickering

Works, was able to detect that a led strip was flickering a lot. Fixed by adding 10000uF capacitor on driver output side. According to app flickering decreased from 97% to 38%. And the eye strain i could previously feel when observing the light was gone. And now I know to avoid that brand of led drivers. Useful for detecting flickering beyond what the eye can perceive, above 60hz or so.

Works like a charm!

Works like a charm! Was worried about a recent light bulb and fortunately tested with this app, now i will replace it. Tested with different bulbs with consistent results.

Works perfectly!

Works perfectly! It shows very accurately if an LED if flickering and to which degree! Saves a lot of hassle and can be pointed exactly at the light you like to analyse!
