BaseSpion Light Measurement System

The bench-top BaseSpion® light measurement equipment is a great tool for any photometric laboratory. It allows you to measure all medium-sized lighting products.

The 2-axis goniometer allows the system to measure the full 3D distribution field of any lamp or fixture and to provide your clients with comprehensive LDT and IES simulation files.

The BaseSpion light measurement system is the perfect solution for any medium-size laboratory that needs advanced light measurements in a compact system. The solution is ideal for measuring LED chips, modules, panels, downlights, bulbs and spots.

The design of the system makes it very flexible to work with in any lighting laboratory. Thepower analyzer and the goniometer drivers are all built in. Just connect via USB to any PC and obtain results in 30 seconds. The BaseSpion is easily connected to your computer via a USB connector. The Viso Light Inspector software is available fordownloadfrom this website. The user interface displays the measured data in a clear and simple way, while allowing for more detailed investigation of the obtained data.


The light source is easily mounted on the goniometer and rotation of the lamp is both fast and silent. The BaseSpion handles light sources up to 9 kg and 560 mm in diameter.

The installation process is very simple too. Place and level the base of the BaseSpion on a steady surface, preferably in a dark room. Mount the goniometer arm and the spectrometer sensor on the base and the system is fully operable within 20 minutes. To obtain accurate results it is necessary to eliminate possible reflections from the experimental environment, so placing a black backdrop behind the system is advised.

The distance between light source and sensor is detected automatically.

The BaseSpion light measurement equipment is then ready for measurement. Install the Viso Light Inspector Software, connect your laptop to the base via the USB-port and start measuring. The process is entirely automatic with the option of manual operation. Data collection from a single C-plane only takes about 20 seconds.

Measurement data is then automatically saved in a specific folder in the form of fixture files. They are usually exported into PDF, PNG, IES, LDT and CSV formats for further presentation in reports. Viso Systems supports customers with comprehensive backup and problem solving, and our distributors and engineers are ready to help on site, via email or phone.
