Modern flicker meter - Not only for professionals

Flicker measurement of light is becoming increasingly important. Especially because light flickering can have negative effects on humans and animals (animal husbandry). And it is especially due to LED technology that this topic is increasingly moving into the focus of attention. Corresponding standards have been and are still being developed (IEEE1789 for the USA, and CIE is also working diligently on limit values and calculation methods).

While flicker%, flicker index and flicker frequency were previously known parameters in the time domain, the new calculation methods (e.g. SVM) require evaluations and representations in the frequency domain.

Now available: The all-rounder can do more than just flicker%, IEEE1789 and SVM

Currently there are several parallel evaluation methods such as flicker%, IEEE 1789, PstLM or SVM and more complex evaluation methods are expected in the future.
Since the evaluation of the LiSens takes place via the app Flicker Measurement Studio on the software side, the measuring instrument is also prepared for future procedures by software update.

High accuracy due to high sampling rate

The LiSens achieves high measurement accuracy by using a V(Lambda) photodiode in combination with a sampling rate of 100kHz with 16 bit resolution. This allows dimmed light to be detected even at high PWM frequencies.
As a pro version, the flickermeter is also available with a 5 MHz high-speed converter for fast samples, e.g. spread spectrum PWM and is unique on the market.
This high measurement accuracy also makes the LiSens ideal for measurements in laboratories and development and is indispensable for manufacturers of lamps/luminaires and LED control gear.


The flicker sensor LiSens is operated and evaluated via a Windows PC or alternatively via an Android tablet or smart device.
This means that mobile use on site is also possible in conjunction with a smartphone or tablet.
