As of May 2026, Asselum, a specialized lighting laboratory in Spain, will take on a new and exciting role as a Viso Systems representative in Spain and Portugal.
Asselum is an engineering and photometric testing company based in Spain. The company focuses on luminaires, LED systems, optical measurement, lighting compliance, and technical consultancy for the lighting industry. Since its founding in 2002, Asselum has become a leading independent photometry lab in Spain. Asselum is highly respected in Spain, in part because it is ENAC-accredited under ISO 17025.
This accreditation means that its measurements are recognized as technically reliable and traceable. Asselum is one of a small number of Spanish labs accredited for these advanced photometric tests, and the first Spanish lab accredited for certain LED lifetime and luminous flux maintenance tests based on the TM-21 and LM-80 methodologies.
It’s no wonder that Asselum is the preferred partner of many local companies in the lighting industry.
Asselum also:
- designs lighting laboratories
- advises manufacturers on compliance
- supports optical design workflows
- helps configure testing systems
- performs lighting audits and train technical staff
At Viso Systems, we know that we have found a truly skilled partner in Asselum, who can help us serve existing clients and build relationships with new customers.
