ASSELUM LUMINOTÈCNICS, S.L. (ASSELUM), founded in 2002 and headquartered in Catalonia, Spain, is one of the country's leading independent testing laboratories specialising in luminotechnics (luminotècnica). The company was established in direct response to the rapid growth of technology and standardisation in the professional lighting sector, and has since accumulated a track record of more than 10,000 photometric tests performed on every category of light source. ASSELUM serves an international client base of lighting manufacturers, luminaire designers, importers, and distributors who require third-party verification of photometric performance, energy efficiency, colour quality, lifetime behaviour, and photobiological safety before products reach market. At the core of ASSELUM's offer is its photometry test laboratory, equipped with state-of-the-art goniophotometers and integrating-sphere systems. The laboratory houses multiple goniophotometer models — including Oxytech rotating-mirror instruments (Type T1, T2, T4, and T5) and the Everfine GO-R5000 goniospectrophotometer — capable of characterising the full spatial luminous-intensity distribution of light sources, LED modules, and complete luminaires. These instruments allow ASSELUM to generate IES and EULUMDAT photometric data files used by the global lighting industry for photometric design and product certification. ASELUM holds ENAC accreditation (the Spanish National Accreditation Entity, Spain's official ISO/IEC 17025 body) for six categories of photometric test. Accreditation was first granted in December 2018 and has since been extended. The accredited scope covers: photometry and colour characterisation per UNE EN 13032-4 and CIE S 025; electrical and photometric measurements of solid-state lighting (SSL) and LED products per ANSI/IES LM-79; characterisation of LED light sources as a function of temperature per ANSI/IES LM-82; luminous flux maintenance and lifetime projection per IES LM-80 and IES TM-21; and photobiological safety assessment per UNE EN/IEC 62471 and IEC TR 62778. This breadth of accreditation under ISO/IEC 17025:2017 positions ASSELUM as one of the few laboratories in Spain offering fully accredited photometric characterisation across both European (EN) and North American (ANSI/IES) regulatory frameworks. Beyond the accredited scope, ASSELUM provides a wider range of laboratory tests to support product development and certification. Services include spectral characterisation of all PAR (photosynthetically active radiation) units for horticultural and plant-growth lighting applications, UV radiation characterisation, colour rendering evaluation per IES TM-30 (Rf and Rg fidelity and gamut indices), colour-shift and chromaticity stability measurements, and ISTMT (In-Situ Temperature Measurement Technique) testing per IES LM-80. The laboratory also conducts interlaboratory comparison exercises in photometry and colour, which allows clients to validate the consistency of their own in-house measurement processes against ASSELUM's accredited reference. The laboratory tests a comprehensive range of light-source and luminaire types: LED packages, LED modules, LED retrofit lamps, LED drivers, conventional luminaires for indoor and outdoor applications, horticulture lighting systems, UV disinfection equipment, and decorative and architectural lighting products. Test pieces may range from small LED components to full-size road-lighting or industrial luminaires. ASSELUM operates its equipment in controlled thermal and electrical environments to ensure measurements comply with stabilisation requirements mandated by ANSI/IES LM-79 and EN 13032 series, which require specific operating-temperature stabilisation periods and precise power-supply conditioning. In addition to pure laboratory testing, ASSELUM provides a complete ecosystem of luminotechnical services. The consultancy arm offers optical design services and lighting simulation projects using industry-standard photometric software, as well as specialised training courses for professionals involved in lighting design, measurement, and certification. ASSELUM also distributes professional laboratory instruments — including goniophotometers, integrating spheres, and spectroradiometers — and optical design software throughout the Iberian market, making it a one-stop partner for lighting companies establishing or upgrading their own in-house metrology capabilities. ASELUM participates in European innovation programmes that reflect its commitment to advancing luminotechnical testing. As a beneficiary of the SILEO (Supporting Innovation in the Lighting Sector through Exploitation and Outreach) programme, and through its "Automation and Digitalisation of Luminotechnical Testing" (ADLT) project, the company is actively developing automated systems to improve throughput, traceability, and data integrity in photometric measurement workflows. Its status as a listed supplier in the Catalonia industry directory and its membership in European lighting cluster networks further confirm its standing as a credible and technically robust testing partner for manufacturers requiring compliance with EU energy efficiency regulations (such as ErP/Ecodesign), ENEC certification, CE marking, and entry into North American markets under ANSI/IES, Energy Star, DLC (DesignLights Consortium), or UL standards.
