Laboratory of lighting tests

There are now an increasing number of products in the lighting sector which makes it difficult to distinguish between good and poor quality products. In our laboratory, with more than 15 years of experience in the elaboration of tests, we test for all types of users in the lighting market, always with the philosophy of impartiality and confidentiality.

Your trusted partner for your laboratory measurements

  • If as a manufacturer or importer you need an objective measurement to know if your equipment meets all the requirements and benefits, we can do it.
  • If, as an engineering /architectural firm, public entity or final user, you need an objective measurement to know if some equipment meets all the requirements and benefits attributed to it, we can do it.

In our facilities, we have 2 goniophotometers and a gonio-spectroradiometer of last generation for the accomplishment of tests of photometry, colour measurements, measurements of the electrical and thermal parameters and analysis of the quality of the light like flicker and the photobiological security.

Test of lamps and lights according to EN 13032-1

Through the test of lamps and lights we provide the values of lamp flux, luminous flux, yield, polar distribution of intensities, electrical power, unglazed ratio (UGR) and colour temperature, among others. In addition, we provide the photometric files IES (.ies), EULUMDAT (.ldt) and OXL. (+ information)

Photometric Testing of Emergency Lights according to EN 1838: 2013

For emergency lighting systems we can provide luminous flux, decay test and colour parameters, among others.

Test of lights and lamps for gardening

Asselum performs tests for all types of light sources for gardening and measures PAR units such as the photosynthetic photon flux PPF and the density of the photosynthetic photon flux PPFD.(+ information)

Tests according to LM79, LM80, TM21, ISTMT and TM30

AThe lm79 has been for many years the only standard for photometric testing of LED technology, before the arrival of EN 13032-4 and CIE S 025. With the LM80 and TM21 we can predict the maintenance of the luminous flux throughout its useful life, while the new TM 30 indicates the new colour parameters such as Fidelity Index (Rf) and Gamut Index (Rg).

Photometry test of lamps, modules and LED lights according to EN 13032-4

By testing all types of LED light sources (SSL) we provide the values of luminous flux, luminous efficiency, polar distribution of intensities, electrical power, unified glare ratio (UGR) and colour temperature, among others. In addition, we provide the photometric files IES (.ies), EULUMDAT (.ldt) and OXL.(+ información)

Test on the quality of light

The light quality tests allow to evaluate the dangerous exposure levels of lamps and lights in accordance to UNE EN 62471 and the Directive (2006/25 / CE) of Artificial Optical Radiation Hazard, in addition to flicker.

Color tests according to EN 13032-4

Asselum has a revolutionary system for the measurement of color and spectrum in different C and Gamma angles allowing to fully comply with the new color measurement standard for LED technology (+ information)

Información sobre el fichero OXL

Asselum ha elegido el sistema OXL desarrollado por Oxytech para el intercambio de datos entre el laboratorio y el cliente y como sistema de gestión de la base de datos. El OXL permite una entrega rápida y sencilla con toda la información reunida en un único archivo. Las ventajas para nuestros clientes es tener la siguiente información en un mismo sitio:


Fotometría exportable en todos los formatos como .ies o .ldt.


Imagen de la muestra ensayada


Parámetros eléctricos de la luminaria/lámpara ( Tensión, corriente factor de potencia, etc)


Parámetros eléctricos de la fuente de luz (por ejemplo cómo se ha alimentado el LED)


Parámetros ambientales durante el ensayo


Espectro de color y todos sus parámetros


Informe de ensayo en PDF


Nombre de la familia y aplicaciones para poder utilizarlo como base de datos(Por ejemplo, tener todas las fotometrías ordenadas por aplicaciones tales como industria, oficinas, viales etc)
