There is a global demand for more efficient products to reduce the consumption of energy and other natural resources, in line with improving overall sustainability.

The LCOE has extensive experience in energy efficiency testing for different types of products. These tests allow us to meet energy labeling and eco-design requirements in Europe and in other areas of the world.

Tested products

We test the energy efficiency of the following product groups:

  • Home appliances
  • Light sources and associated equipment
  • External power supplies
  • Electrical and electronic equipment for home and office use
  • Televisions, etc.


The photometry laboratory offers a service to manufacturers of lighting fixtures and sources to determine the light emission characteristics and thus provide fundamental criteria for lighting projects, which are increasingly in demand by engineering in construction and renovation projects for buildings intended for homes, offices, schools, industries, sports facilities, etc.

The laboratory is equipped with two goniophotometers, which together with the most advanced software, makes it possible to offer complete photometric information, with great precision and for a wide range of luminaires, from projectors to small emergency lighting luminaires.

The main photometric data obtained is the following:

  • Intensity matrix.
  • Polar diagrams (in 2D or 3D).
  • Measurement of luminous flux of lamps.
  • Luminous output rate (LOR) of luminaires.
  • Color quantities.
  • Zonal flows.
  • Utilization factors, according to UTE Standards, LiTG, CIBSE, etc.
  • Isolux diagrams (in 2D or 3D) .
  • Diagrams of glare, of zonal flows, etc.
  • EULUMDAT, IES, CIE files, etc.
