Read what a few Viso clients think about their goniospectrometer projects, operation, cost savings, capacity and software.


P.T.I.C, Belgium

We bought our BaseSpion in 2022 to measure all lighting details and to fulfill the requirements of the European EPREL.

We were also able to create more professional technical data sheets and to massively improve the efficiency of our luminaires.

With the Viso team we had a super professional support and a willingness to help at all times, i.e. I was never left in the dark. In short: An exemplary product and an exemplary service.


Fraen, USA

We have owned a LabSpion since 2018 and it has produced hundreds of measurements correlating closely to results of independent laboratories.

The LabSpion just works. The system is durable, easy to use, accurate, versatile, and can be easily moved.

The LabSpion enables us to design, prototype, test, then tool, mold, and test our complex plastic lenses and reflectors better, faster and cheaper.


The LabSpion allows us to create our own IES files, that are published on our website.

Before we outsourced ALL of our photometric testing, which was a costly and time-consuming process.

We use Viso daily to assist with product development.


Lund University, Sweden

At Lund University, Sweden, we do research in flicker/Temporal Light Artefacts.

With Viso LabFlicker we now have a measurement instrument, which is easy to use and demonstrate to the students.


Orluna, UK

The LightSpion system saves us waiting 2-4 weeks for IES files from an external lab.

With our own system we can run thermal improvements, beam shape improvements, and LED selection.

R&D is faster and we are able to prototype accurately.


Liteline, Canada

With the LabSpion we now measure more than a dozen lighting fixtures per week.

The ability to measure ‘color versus angle’ is very helpful and is a unique Viso Systems feature.

Reduced cost from using external labs means the system was paid back in less than 1 year.



We can now turn round any measurements within a matter of minutes.

It has helped make more educated decisions to inform our design process. Ensuring the quality of light is fully understood throughout.

This has helped get products to market quicker, which in turn influences the growth.

Matteo Botner

Botlighting, Italy

After developing an internal test facility, we have been much quicker and more effective in selecting materials and partners.

Customers appreciate that the company has the right instruments for R&D.

This has improved our reputation in the market.


Korona, Germany

The use of LED technology required us to do much more measurements in R&D.

The LightSpion + Extender also made it possible for us solve specialized high-end projects

Before, it took two weeks to get a single measurement done by an external lab and would cost €650

Håkan Jordanson

Nokalux, Sweden

LabSpion has reduced our measurement time significantly to an average of 8 minutes per fixture.

Before we paid €800 for a measurement at an external lab. Before, we measured manually with a custom-made jig and a lux-meter.

 The quality of our lighting fixtures has increased as we test faster.  

John Cheung

Retc, Hong Kong

BaseSpion and LabSpion allows us measure 50 lamps per week.

Viso help us to save time so we can focus on quality aspects.

The system was paid back in less than one year.


Molto Luce, Austria

With LabSpion we are faster in the engineering phase, so we are able to bring the products to market more quickly.

We primarily use the system for measuring prototypes, i.e. the efficiency of our optical solutions.

Martin Nähr

Stella, Brazil

The LabSpion in our internal lab makes it possible to quickly compare our products for both quality control and for competitive purposes.

Fast product comparisons have improved our sales process.
