ACCIONA Producciones y Diseño was pioneer in 2008 by installing LED lighting in an entire museum.


As the world becomes more and more aware of the environmental impact that any activity, product or service may have, most museums now take into account not only protecting their artistic collection but the museum’s actual surroundings as well.

One of the essential aspects for ensuring the conservation of pieces on display is, together with the air-conditioning of the rooms, the lighting itself. Care must be taken that recommended levels for conservation are not exceeded, that the tonality is adequate for the object being lit, that no heat is emitted or that they have very lowultraviolet filters so that the objects are not damaged. Lighting, moreover, consumes as much energy as air-conditioning and for this reason that, in the last few years, use of LED lighting has become pervasive as it both increases energy efficiency while at the same time reduces the carbon footprint.

As a premise in our studies on lighting, the object is always to highlight the contents of the exhibition in their different areas, without taking away the protagonism of the building’s architecture. There is, in fact, every effort to integrate the lighting in the area such that the sources of light remain unnoticeable to the public.  In this way, the visitor’s attention is focused on the information and exhibition contents. To achieve this, an exhaustive study is made as much as for the location of the different projectors being used as for the technology.

ACCIONA Producciones y Diseño was the first Spanish company to do the complete lighting of a museum using LEDs. It was in 2008, in the Museum of Underwater Archeology (ARQUA) of Cartagena, and since then all our design proposals for museums include this technology. Even where we are only involved in the technical development and execution and there is already a design with analogical expositive lighting, we attach a report showing how the change to LED lighting would benefit the design.

So, although we did not design the Jewish Museum and Tolerance Center of Moscow ourselves, we were able to install this technology in the buildings, as well as in our present projects in the National Museum of Oman and the Boris Yeltsin Presidential Center in Yekaterinburg, to name just a few, as the advantages greatly outweigh the disadvantages.

Advantages and disadvantages of LED lighting


  • Long life, the current average is around 50,000 hours.
  • High flow levels and directed intensity.
  • Significant size for multiple and different design options.
  • Highly efficient, energy saving.
  • White light as well as in all colors (form 460 to 650 nm).
  • Low voltage and consumption requirements.
  • Highly resistant to blows and vibrations.
  • No ultraviolet radiation.
  • Can be easily controlled and programmed.
  • Low emission of infrared radiation.
  • Does not contain toxic products nor damage to the environment.
  • Turns on quickly.
  • Permits the use of filters.


  • High cost, although prices are becoming more competitive.
  • Power source must be near the LED, even though some manufacturers permit installation up to 80m from source.
  • Low output at high temperatures.
