Combined AC and DC power analyzer

Revolutionary: Measure strobe lights while they are flashing

Measure flashing light


Viso LabAnalyzer is an advanced AC and DC power analyzer that complies with light measurements standards (IES LM-79 and CIE S 025). LabAnalyzer fully integrates with your Viso light measurement system and software, and facilitates remote sensing (measuring voltage directly at the light source terminals).

Revolutionary: Measure flashing light sources

One of the two LabAnalyzer models makes it possible for the first time to perform a full 3D light distribution on a strobe lamp – while it is flashing.

This is achieved by synchronizing a Viso sensor with the current pulses measured by the LabAnalyzer. This allows you to accurately measure flashing light sources.

The system even measures the details of the flash waveform, peak voltage, amperes and intensity, period length, number of flashes per period, flash lengths and interval lengths, etc.

This is done by synchronizing the integration time of the sensor with the current readings, which is a new, revolutionary system. Never before has it been so easy to measure strobe lights.

Watch the video on measuring flashing light sources.


If your light sources do not flash, LabAnalyzer also comes in a model without the synchronization option at a lower cost.
