London is about to throw a lot of money into the Thames


Comment by Joachim Ritter

At the risk of not being allowed to cross British borders in future, I simply cannot hold back my open and honest opinion, which many people will no doubt share anyway. The Brexit referendum was already a fiasco, but it seems we are in for an even greater fiasco if you look at what is being considered as the winning lighting schemes for London’s bridges over the Thames. Whoever dared to believe “it won’t be that bad” is in for a shock. The jury is destined to fail collectively when selecting “the winners”!

A few months ago, experts from the field pointed out that a lighting design competition involving significant prize money and focussing on a project of the calibre of London’s bridges over the Thames should not take place without including a representative number of qualified lighting designers in the jury. And yet all this advice achieved was to invite a few lighting professionals to take part in the preliminary review of the submissions. I am not sure if Speirs & Major, for example, had any influence on the jury’s decisions through their part as preliminary reviewers. To be honest, I can’t imagine it. It simply doesn’t fit into the philosophy of this world-renowned practice to allow a river of the standing of the Thames to be so maltreated by light. And I also find it hard to believe that the shortlisted designs were selected from more than one hundred submissions from 20 different countries. If these are supposed to be typical of the status of the quality of lighting projects in this day and age, then we are taking a dramatic step backwards. I cannot believe that. This is an insult to the professional lighting design community and can only mean that some of the approaches taken have nothing to do with lighting design. On closer inspection of the submissions and the jury, I can only come to the conclusion that the outcome is due to ignorance as to how lighting design is defined. The results are not representative of good lighting design – which is pretty inconceivable when you consider that jury members apparently included the likes of James Turrell.

Defining searchlights as a design element for the City of London and describing this as a way of saluting the night is really not on. It is an open attack on the darkness of the night. This was a topic for discussion some time ago, and should be considered as resolved. To even refer to this approach as “Synchronizing the City: Its Natural and Urban Rhythms” is nothing less than insensitive. I will refrain from going any deeper on searchlights and their link to military operations. Sorry: this was really the wrong choice, and does not fulfil the actual task, which was to illuminate the bridges, some of which are definitely architecturally interesting. Why were the inherent qualities of the bridges themselves not sufficient for the team to focus on? Was it really necessary to salute anything?!


“Blurry Boundaries”: London Bridge wallpapered in light. The structure is nothing more than an object that can deliver a surface for a blurry concept, ultimately termed “invisible ripples”. The latter were rendered visible with all the might and main that light can possibly impose. What happened to the respect for the architecture and engineering? And for the way the bridge is designed to function? Lighting design is not a fashion issue. Waterloo Bridge has received a kind of art nouveau treatment, becoming a decorative element in its own right that dissolves the bridge and, if realised, would force the bridge to adopt a secondary role. Inacceptable. Westminster Bridge incorporates the most promising approach. Digital, a discreet reference to history, and with an interesting time component touch. The design concept that sets this bridge apart unfortunately leaves one questioning what on earth the idea behind the Chelsea Bridge concept was. The colour design is apparently arbitrary – certainly not based on a clear concept. What has this to do with blending in with the urban environment? Master plan – no chance. Overall appraisal of the team: instead of a clear concept, Blurring Boundaries marks the escape from design to art, which is hard to take lying down.

The concept for “Current” is at least based on the idea of a master plan, which is good for a start. And it has been realised in a consistent manner. Unfortunately, it only works on paper and in drawings. In reality, from the human perspective the bridges come across as a series of blotches of colour. Nothing seems to be related to anything else; there are no references to enable anyone to recognise an overall concept. The work therefore loses any sense of meaning and ends up an unexciting mystery. It’s only Westminster Bridge that appears to be more human-oriented and accessible, because the historical essence remains intact.  Interesting! And Chelsea Bridge is acceptable, to say the least.


“Thames Nocturne”. In the case of this design the meaningfulness of light has not been addressed at all. What is the intention? To cover the Thames in lightwaves? Design approach aside, this concept smacks of armchair reasoning. It is absurd to even believe that this could ever be realised. Every beginner in the lighting design world knows that light is only visible when it is reflected by a surface. But summer nights are dry – no humidity to speak of, no visible light! What about the boats on the Thames – they would interrupt the light, wouldn’t they? And there doesn’t seem to be an end to the belt of light. Is someone going to stop it at some point? Including this in the shortlist is nothing less than embarrassing for the jury!

“River Ain’t Too Much To Light”. At least some thought appears to have been put into this one. Realised by creating lighting effects on the bridges. Of course, anything is possible, but gobos, quite honestly, are a bit superficial for this kind of application! It’s difficult to fathom what exactly the designers wanted to realise here. Maybe the architectural design of the bridges differs too greatly to draw any comparisons. As a consequence, Chelsea Bridge is way too bright. And planting street lanterns in the river is truly a “do without”. Good way of saving energy, I suppose!

1-c-mrc-and-les-eclairagistes-associes“The Eternal Story of the River Thames”. A concept with a meaning at any rate. The Thames breathing through light. The embankments are lit depending on the water level of the river. If it is possible to ensure the lighting is designed to be relatively discreet, this could indeed lead to an interesting and good outcome. In this concept, the bridges play a modest but crucial role. Not as a colourful festival-like backdrop, just bridges lit in white light. If the designers opt for the right colour temperature, this could also be developed to become a good solution. Care needs to be taken with regard to flora and fauna when realising such a project. The designers and the client may need to reach a number of compromises.

Perhaps the result of this competition is an indication of the fact that light festivals and light art can indeed hamper the development of good lighting solutions in the public realm. The results are to a large extent nothing more than a chance for the designers to draw attention to themselves and how versatile they can be with light. Some of the concepts submitted treat the architecture as if it were of secondary importance. That has little to do with lighting design.

Preface to the Call For Papers


Dear Friends of PLDC, dear Lighting Design Community,

The sixth edition of the Professional Lighting Design Convention, PLDC will be taking place in Paris/F from 1. to 4. November, 2017. This may initially sound or read as being pretty much matter-of-fact and sober. But it in fact marks something very special and a real chance for the lighting design community. Allow me to elaborate on this a little.

Over the last ten years, since the very first PLDC in London back in 2007, we have – through PLDC and the PLD – witnessed and been part of a fundamental change in the lighting design world. In London, those present adopted a Declaration on Lighting Design as a profession for the first time. This was disseminated worldwide, providing the initial impetus for many to become pro-active. In the meantime, the Declaration has been translated into different languages and has served as the basis for defining a lighting designer’s scope of work and responsibilities.

And yet here we find ourselves, ten years later, on the threshold of an even more radical change – in both the technological sense and with respect to the profession. The motto for PLDC 2017 in Paris is “Shift happens”, which couldn’t be more apt. It was not without reason that we opted for Paris as the location for the next PLDC. This motto is equally meaningful for the City of Paris, given their reputation as the first City of Lights.


The PLDC team have continued to develop the event over the years, expanding the conference and the accompanying programme and aligning it to address current trends and requirements. The market has responded with gratitude and increasing interest, as the growing numbers of attendees show. In 2007 we recorded over 1000 attendees, and at PLDC 2015 in Rome we attracted 1700. There is every indication that the number of PLDC attendees in Paris is not likely to be below that of Rome. Our objective is to be the largest effective platform dedicated to the development of Lighting Design worldwide.

But it is not the number of attendees that decides how successful a PLDC is, but rather what results from the papers presented and the other educational opportunities and discussions on and around lighting and the profession. The higher the quality of the content and the presentations, the more dynamic Lighting Design will be able to develop. The more interesting and interested the attendees are, the greater the chance is to change the market and play a pro-active role in achieving that. In past years, PLDC has sent out strong messages – with effect. Key developments, and even trends have been born at PLDCs and established in the industry as a whole. This is where ideas are presented and solutions found. But this is also where critical issues are raised, and discussed and debated openly. PLDC is THE international platform for independent, state-of-the-art lighting design – not to be missed if you want to be part of the future.


In Rome, a Think Tank comprising seven experienced professionals from the world of architecture, lighting design, lighting education and research, and with experience in working with public and private clients, met to analyse and discuss PLDC and the lighting design market. The Think Tank discussions concluded by defining PLDC as the “Thought Leadership Event” of international lighting design. As a concrete result of these discussions, we have taken it upon ourselves to take crucial steps to develop PLDC and accept responsibility for the market. VIA-Verlag has undertaken everything in the last few months to create the right framework to provide the international market with an appropriate platform.


Now it is up to you – the lighting designers, researchers, educators, architects, clients and, of course, the lighting industry, to fill this framework with life. We are looking for the best, the most future-oriented and relevant contents for the best community of lighting specialists, who come together in the same place at the same time to learn and discuss what the future holds in store. We are not looking for lectures which have already been presented and discussed elsewhere, but for approaches and information that is new and can inspire us all to overcome the challenges of the future. We are looking for designers and others who are prepared to work together to shape the lighting design world and gain the recognition for the profession that it deserves.mediale Stadt


Do not restrict your input to simply responding to the Call for Papers, but consider this overall process as a real chance for Lighting Design. Take the time – through your cooperation, your know-how and your thoughts – to be part of the start of a further development in the lighting design world. We have engaged the assistance of more than 20 practising professional designers to read and evaluate your submissions in a blind review process. You can be sure that this will enable us to again compile the best possible programme for the coming PLDC 2017 in Paris.

It is now up to the lighting design community, and to you personally, to again make PLDC an educational event that will benefit every individual attendee and support the call for recognition of the lighting designer within society as the truly qualified expert when it comes to all aspects of designing with light.

Are they serious?

Competition for lighting design and light art … without any lighting experts on the jury!

The City of London is rated as one of the world’s largest cities. Along with Paris, New York City and Tokyo, the British capital ranks as a trendsetter.

And this also applies to lighting design. Many designers are based in these huge cities, and work from there. Wouldn’t you think that means that there should be a sufficient number of professional people in London, for example, who have know-how and expertise when it comes to judging the quality of light and lighting?

The City of London recently launched a design competition to illuminate 17 bridges along the Thames from Albert Bridge to Tower Bridge. The competition finalists will be asked to conceive a design masterplan for the project, while providing a concept design for four specific bridges Westminster, Waterloo, London and Chelsea. The winning concepts resulting from the international design competition are to be realised by 2018. So far, so good.

What is rather strange about the whole set-up is that not one of the seven jury members can claim to be a lighting expert. That doesn’t mean to say that Lord Rothschild, Architect Malcolm Reading, Prof. Ricky Burdett representing Urban Studies, or Justine Simons, Head of Culture at City Hall in London, do not or should not have an opinion about light and lighting. But not to have any expertise at all when it comes to judging the quality, contemporary nature or feasibility of any of the design proposals submitted smacks of gross negligence to me. The design criteria stipulate that the design needs to display outstanding aesthetic quality, show innovation and incorporate energy-saving technologies, and feature interactivity. Who in the jury is able to address such issues when evaluating submissions?

This again shows that “people” are certainly aware of lighting design in architecture, but not aware of who lighting designers are and what their skills are. Neither associations nor education programmes have managed to establish themselves as an essential part of design competitions of this kind. Apart from the fact that in this Call for Proposals the boundary between lighting design and light art seems to be more blurry than it is helpful. The competition claims to be looking for a public art installation, while the strategic priorities contained in the brief give the impression that it is a lighting design they are looking for. To be honest, it is hard to decipher exactly what the expectations are.

All that remains is for the professional lighting designers (or light artists, who knows?) to use the competition to set themselves apart from other disciplines and to call attention to the difference they make.

Iconic building


The new Harvey Nichols concept store at The Mailbox, Birmingham, is at the heart of the iconic Mailbox building and has been purposely created to offer 45,000 square feet of luxurious retail space. By totally transforming the retail environment using cutting edge technology and purposefully designed ambient lighting, the store now offers a more sophisticated shopping experience.

small HarveyNichols-03This state-of-the-art retail facility has become the blueprint for future Harvey Nichols stores. The lighting was designed by PJC Light Studio Limited, London, who homed in on two of the most prestigious of our fittings to be used in a wide range of areas across the store, including womenswear, menswear, perfumery, lingerie and shoe departments.  Over 800 large YORI luminaires incorporating  30W LEDs were selected in black, mounted onto existing tracks and placed within black channels to blend seamlessly with the dark ceiling design. Equipped with a narrow-beam reflector and a cross-blade louvre to eliminate glare, the YORI luminaire offers precise illumination that is ideal for accentuating merchandise areas and can easily be adjusted for more defined lighting control.

Small HarveyNichols-09Fabio Cristini, lighting designer at PJC commented: “With challenging ceiling heights of 4.2 metres in particular areas of the store, it was imperative to ensure we had a good delivery of lumen output and a wide range of beam angles to allow us to create the right ambience for these areas. Reggiani’s YORI fitting is also aesthetically pleasing – another important consideration.  The performance of the YORI is very good and the use of the cross-blade louvre accessory was invaluable for this high-end retail project”.

PJC specified the large YORI luminaire in white for the lingerie and swimwear department with the fittings, once again, mounted on existing tracks but within white ceiling slots against a white ceiling to create a very different style for this part of the store.

small HarveyNichols-05The extended and luxurious changing-room space for the new store utilises round Trybeca recessed luminaires equipped with 8W LEDs. The Trybeca fitting complements the opulent design of the very spacious changing area and harmonises well with the existing, relaxing surroundings, whilst providing excellent quality light – an absolute imperative for superior changing-room for discerning shoppers.

About Pompeii… or what remains of it


A large-scale exhibition project developed to recount the fascination that the archaeological site of Pompeii held for artists and the European imagination, from the start of excavations in 1748 to its dramatic bombing in 1943. This is “Pompeii and Europe. 1748 – 1943”, an exhibition open to the public from 27 May to 2 November 2015 at the National Museum of Archaeology in Naples and simultaneously at the Amphitheatre in Pompeii, with the patronage of Expo Milano 2015.

Sponsored by the Soprintendenza Speciale per Pompei, Ercolano e Stabia and by the Management of the Grande Progetto Pompei, in collaboration with the National Museum of Archaeology in Naples, the exhibition – organised by Electa with installation by Francesco Venezia – is structured as a true journey, grand and complex, in which Antiquity enters into a dialogue with Modernity, and nature with the arts and archaeology.

The exhibition is divided into four chronological sections containing works of various types: paintings, drawings, collections of prints, architectural plans, photographs, sculptures, objects, books and more.

The variety of items on display and the artists involved show how Pompeii, with its buried ruins and its classicism, has fascinated artists from all over Europe for nearly two hundred years, from Ingres to Picasso, Normand to Le Corbusier, Moreau to De Chirico.

The dual exhibition venue features two separate lighting concepts, different but at the same time complementary.

The design for the Naples site centres upon the concept of “working on memory”, using light to showcase objects thematically linked to each other but made centuries apart.

In order to bring together this highly heterogeneous display, the illumination of each piece must be similar but perceivably different, using the “vibrated light” technique. Vibrated light involves alternating different light beams using two 3000K light sources with different spectrums, dimmed individually.

The constantly changing light spectrum in the environment is perceived by the human eye but is not visible on the painted surface of the works; it therefore appears as a continuous vibration.Axonometrie 1

The vibration is appreciable if there are other illuminated surfaces within the space, stable by contrast, which act as a comparative element, bringing out the vibrated light system.
For this project, 10 Watt track-mounted Yori LED projectors were chosen, featuring a special cone louvre with 3 beam widths: 12°, 15° and 20°.

The precise adjustability of the projectors allows for optimum positioning which minimises any bouncing of the luminance caused by the multiple glass elements present.

The Pompeii installation features a different concept: whilst in Naples the visitor experience does not take in the totality of the setting at first glance, in Pompeii the light immediately draws the eye to the spectacular architecture of the space as a whole.

The main problem with the round geometry of the setting was controlling the luminous flux output. To remedy this, special brackets were created to allow the Linea Luce Slim LED linear System used to be directly mounted on the arch of the dome.

The consistency between the two lighting designs ultimately lies in the role of the natural light, which is integrated, in both cases, with solutions selected to reduce energy consumption.

Recommended reading – books to look out for at PLDC in Rome


This year, the VIA team has once again come up with a selected list of books for recommended reading. They will be available at PLDC in Rome for you to take a look at. Some of these books will be available for purchase for the first time at PLDC.

See the light free“See the Light” by Svante Pettersson, the experienced Swedish lighting expert, has gained substantial popularity over the last few months. The generously illustrated book depicts, from a Scandinavian viewpoint, how light works and how to differentiate between lighting solutions. “See the Light” is especially valuable for all those who like to see the work that they and other like-minded individuals perform daily confirmed in book form. “See the Light” is a standard work, a highly inspirational book about light, the philosophy of light and the art of getting to know your visual sense, which in the end boils down to common sense. A detailed critique can be found here.


Buch von ChristopherThe complement to Svante Pettersson’s book is the latest work by Christopher Cuttle. From its title: “Lighting design: a perception-based approach”, it appears to be a book about a specific design approach. Correct, although all the perception-related information is scientifically proven in numbers before the design concept is realised. Christopher Cuttle always manages to unlock yet another part of the true world of lighting design. A detailed critique can be found here.





light-shadow_01Aleksandra Stratimirovic is active in the overlap between lighting design and light art. Together with Sandra Praun, she has published a book that makes this overlap the core of the work, even rendering it visible in the way the book itself is designed and presented. “You say Light – I think Shadow” is a collection of comments and statements from leading architects, designers, artists and other key figures who have recognised light as being a central part of their lives and wish to share this with others. At the same time, the work itself is a huge compliment to ‘the printed book’ as a medium, and is informative and inspiring throughout. A detailed critique can be found here.

Modeling Daylight englishA new book, which will be presented at PLDC for the first time, incorporates discussion and a collection of experimental studies on the topic of daylight. Giovanni Traverso has put together a practical manual based on his own perception of the topic plus a series of studies carried out by students which take a close look at a creative approach to designing with daylight. “Modelling Daylight” is designed to promote discussion on the purposeful use of daylight. It is an impressive documentation of the creative power daylight can have in architecture – an inspiration and practical manual in one. The principles of daylight design are presented clearly and in a well-structured way, and examples shown that enable a practical approach to follow on from the theoretical fundamentals. A detailed critique can be found here.



All books amoung others can also be purchaised through the VIA shop here.

Characters in the lighting industry: Rogier van der Heide


by Joachim Ritter

It is often the characters circulating in a particular industry that give it its inimitable “flavour”, special characters who tend not to mince their words, who everyone knows, and who often leave the community split into two: those who are declared fans, and those who do not share that level of enthusiasm.

Rogier van der Heide is one such character, the lighthouse among all lighting experts. Formerly a lighting designer of the category IALD Full Voting Member, he is still a lighting designer, but one who is firmly positioned on the other side of the fence and is now regarded differently, or sometimes ignored, by his former independent colleagues. That does not mean that he has not maintained the skills to design lighting or that he has lost any of his design qualities. But the purists in the lighting design world tend to presume the latter is the case. Rogier has opted to view lighting design from another perspective. To be honest, at least he has the advantage of being able to spot developments and potential before many independent designers can do so. And yet many lighting designers cannot, or do not want to, accept this.

At times, Rogier van der Heide can be a bit of a Fidgety Philip. He is regularly invited to give a talk at events around the world. Standing on the stage, doing his best to impart his know-how, he simply cannot stand still and needs two to three square metres, sometimes gesticulating wildly, to express his opinions and communicate his statements. His long blond hair falls forward, half covering his face, and everyone can see how pointless it is to continually attempt to push it back or to one side. For a split second you can see his face and his eyes, which usually look pretty tired given that he spends a lot of his time jetting from conference to conference to represent his current employer through his unique charisma. As a rule, Rogier has to bend over to have a meaningful conversation with an individual. And everyone is waiting for the moment when he engages in a dialogue with Kaoru Mende.

His texts can be clever and witty, and laced with his special sense of humour. Even the way he embarks on a presentation at a conference is unique. Whereas all other speakers graciously thank the organisers for the invitation and opportunity to give a talk, Rogier van der Heide thanks the audience for attending his lecture. Sounds plausible in the first instance, but completely ignores the fact that attendees may also value other speakers and are sitting in the audience because they will also be presenting. Looking back on his professional career, he sometimes associates it with a bike ride from Amsterdam to Dornbirn. Who else, apart from Rogier, would come up with such an analogy? But you can’t really hold anything against Rogier, not anymore.

Roger van der Heide is able to put together presentations and communicate messages that remain in your head forever! Not always, but sometimes – and at any rate no less frequently than any other lighting designer who can go on for hours about his/her career as an independent lighting designer.
Rogier has stopped growing in height, but not when it comes to content. Which is why he continues to find fans and followers around the world who are inspired by his observations and knowledge and his dry sense of humour – or sometimes not.

An industry thrives on the community that forms it – special characters, like Rogier van der Heide.

LED-Linear to provide funding for the first endowed professorship at the University of Wismar


stiftungsprofessur_wismar_1-sIn the past years we have been honoured to welcome some of the greatest partners in the industry to PLDC. The exhibition staged for their benefit was certainly not of the standard format. The special quality of PLDC is that the conversations and discussions that take place there lead to new ideas, new developments and solutions. The exhibition hall at PLDC is a vibrant hub for such activities, and in that sense points the way to the future.

One company that has developed extremely well in recent years is LED Linear. LED Linear have been a Partner of PLDC since 2011. They have won a number of design awards in the meantime, but have also opted to assume more responsibility to support the interests of designers. This year LED Linear embarked on a new project in support of the lighting market of the future…

On 9. July, 2015 LED Linear signed an agreement with the University of Wismar to establish and finance the first endowed professorship, thus building a bridge between business and science, and making an essential contribution to strengthening the Architectural Lighting Design degree programme at the University of Wismar. The professorship is limited to five years and LED Linear will be providing a six-figure amount to partly fund the costs for the professorship.

CEO Dr. Michael Kramer: “For us it is especially important to make a significant contribution to the advancement of research in the field ‘Lighting Design’. The targeted support and training of highly qualified young people is extremely important to us”.

The responsibilities linked to the professorship comprise the usual list of tasks and include teaching, academic administration, the supervision of theses and the processing of further assignments in the context of studies. One prime focus will be the exploration of new fields of application of light in buildings incorporating linear lighting systems, both from an economic standpoint and with regard to the development of new approaches to product and application designs.

On signing of the agreement, LED Linear CEO Dr.-Ing. Michael Kramer, and the rector of the University of Wismar, Prof. Dr. jur. Bodo Wiegand-Hoffmeister gave to understand that the endowed professorship is a mutually beneficial step for both parties. The university will benefit from the additional teaching activities, and the market can look forward to an expansion of marketable LED applications.

Modeling Daylight


Inspired by daylight – A book on experimental creative use of daylight
A critique by Joachim Ritter

Modeling Daylight englishThe apparent reason for so little daylight being used as a design element in architecture is that a large number of designers lack the know-how and skills to handle it. Their creativity, you might say, does not go beyond the rectangular window opening. One way or the other, every room looks more or less the same: square. You feel you are trapped in a box, although there are enough windows to escape through… Thinking out of the box is (literally) becoming increasingly more difficult. And there is not much in the way of literature when it comes to how natural light can be used as a design element in an architectural space. New requirements related to energy savings and what planners tend to perceive as the ‘enforced use of daylight’ has put us in a situation where we can no longer make out what is light and what is architecture, because everything is simply overly bright.

Inspiration is called for. This is where the book “Modelling Daylight” by the Italian architect and lighting designer Giovanni Traverso comes in. As the initiator and head of the summer course entitled Daylight Thinking that took place in Vicenza/I in 2012, he and his students created a series of models to demonstrate that through daylight interior spaces can gain a quality that has nothing to do with rectangular openings set in the facade. Daylight can become the main feature in a space, if the designer is able to handle it creatively.

The manual aims to raise awareness and make readers sensitive to the idea that light can become a fundamental element in architectural design, capable of positively modifying the experience of the user.

The book motivates and encourages readers to return to the purposeful use of daylight. But it is also a manual containing helpful references and feasible approaches, and in that sense goes beyond the purely experimental. Time and again when reading the book, one is inclined to reconsider one’s own philosophy of natural light and place more importance on the use of daylight in architecture on an everyday basis. Which is as much as to say that this is not a book that will simply added to the bookshelf and disappear forever, but always be within reach as a source of reference. It is not a sequel to grand works such as William Lam’s “Sunlighting as Formgiver for Architecture”, but defines a new lighting design quality that is achievable through daylight.

With this book, Giovanni Traverso has succeeded in providing convincing material on the purposeful application of daylight. The information, data and reports on the studies are presented in a clear, well-structured manner. His ideas on daylight design and commitment to spreading the educational word come across confidently and are easy to follow. “Modelling Daylight” is sure to be more than just an inspiration to those who read it.
