The light flicker meter LiFli enables the fast evaluation of light sources on their flicker content.
Especially with LED illuminants the flicker ratio can be only determined by a measurement, since with these, the rate varies from 0% to 100%.
A bar graph shows the flicker percentage of a light source in 18 steps:
2% 4% 6% 8% 10% 15% 20% 25% 30% 35% 40% 45% 50% 60% 70% 80% 90% 100%
Audio functions allow an acoustic reproduction of the flicker.
A voltage output is provided for further analysis by an oscilloscope or a spectrum analyzer.
The sensor is located on the front of the LiFli. The spectral sensitivity is similar to that of the human eye.
The sensor detects the flicker in the range of 50Hz to 400kHz.
