#SpectralRoom: Discovering Multispectral Lighting with Mariel Fuentes

We will soon be unveiling the #SpectralRoom: An Immersive Experience designed by Mariel Fuentes, director of the LDLUZ lighting design studio, at the LightLab of Lamp, located in the Lamp HQ facilities in Terrassa.

While this experience was designed to take place within the Light+Building 2020fair, it has now been moved to Lamp's showroom, enabling the opportunity to discover, through the use of light, audio and imagery, an innovative and avant-garde technology: multispectral lighting.


Knowing how important it is to unite design, engineering, and technology to anticipate different needs and create new lighting solutions that can address new projects, we are pleased to have joined forces with our technology partner Ledmotive and Mariel Fuentes (LDLUZ Lighting Design), with whom we have designed this multispectral lighting experience and have helped us to create something that, without a doubt, opens the door to a universe of lighting possibilities.

We learn a little more about the #SpectralRoom experience and how the project came about in a conversation with Mariel Fuentes.

The collaboration between designer and manufacturer

According to the designer herself, "the #SpectralRoom is an experience that invites you to immerse yourself in infinite possibilities regarding how to live and feel the light, and what it says to you in each moment".

Mariel Fuentes points out that this project "was born from the desire to create synergies with Lamp, after discovering the company's approach to the use of new technologies that generate new stimuli for the user through light. I found the way in which you were working on technology so interesting, that both sides expressed a desire to create a professional exchange between you as developers and us as designers, to generate new things.

"After several months, the possibility of collaborating in developing a part of the Light+Building Stand that was the core part of it arose". The #SpectralRoom was not merely intended to convey technical information, but "we wanted the visitor to experience it".

Unlike a lighting project that is focused on the user, the space, the activity that takes place in it, which usually endures over time, with a typical user that develops consistent uses, etc. By generating a lighting experience "our goal was to stimulate the senses, generating a unique experience based on each person's point of view, having a different experience according to each person's background". For the #SpectralRoom, the goal was to surprise with a dynamic and customised interaction with the lighting as the main thread. The inspiration or motivation when designing the project was to explain something without saying it explicitly and to use other components (apart from light) as visual and sound stimuli to "transport the user to the emotions we wanted to achieve through an abstract narrative".

According to the designer, the greatest challenge of the project was "catching up with a group of highly trained professionals and having to understand from scratch a technology that I didn't know and immerse myself in it to be able to narrate it”. However, starting from scratch also helped to understand how someone who was not familiar with the technology would receive that information from a visitor's perspective, and to build a more understandable message to spark their interest, so that they could then go to a professional with technical knowledge and discuss the topic in greater depth and elaborate on the product.

Mariel also pointed out that "this technology is a fantastic tool that opens up infinite possibilities, not only for health-related projects, but also for other more functional applications and to deepen certain experiences". However, although technology developers are assuming the paradigm changes that are already happening in the lighting industry, the market is slowing down, and the industry needs to be educated about the importance of quality lighting.

Personally and professionally, Mariel describes the collaboration on this project with Lamp as "a challenge as well as a gift; a very nice experience. The willingness to collaborate both ways and that each one contributed their share greatly enriched me while at the same time generated a constant stimulus. In short, I am very grateful and I hope that the experience is repeated, because I think that lighting manufacturers are our (designers') partners and we have to encourage these collaborations and continuous learning”.

What is Multispectral Lighting?

Multispectral lighting represents a rupture in the traditional lighting paradigm, as the combination of 7 different colour channels makes it possible to design any light spectrum among 1025 potential designs available.

All light parameters can be maximised or minimised: CCT, CRI (Ra), CIE x,y coordinates, TM-30-18 Rf, Rg, etc. at any time and/or place.

In addition, multispectral lighting digitises light considering the following possibilities:

  • Generate light patterns at a spectral level, not just by modifying colour temperatures;
  • Create lighting libraries in the cloud;
  • Record and reproduce any light spectrum;
  • Set parameters selection online;
  • Design dynamic light spectra.
