CITY AND LIGHT
Let us start by defining a lighting plan.
What does it do ? What added value does it have ?
The lighting plan is a plan of action produced on the basis of a lighting development
master plan. Its main function is to compile an inventory of the existing state of lighting in
a city. Then a series of actions and investments are planned in order to define a coherent
nocturnal image for the future.
The initial period of reflection allows the identity of a city to be defined, and the way in
which its image will be communicated to be determined. Its characteristics and
favourable aspects are all inventoried.
The inventory also leads us to discover elements of a city that nobody has previously
imagined could be highlighted. It allows the districts to be revealed and the links
between them to be drawn together. The lighting plan can also help develop a
“light culture” among everyone involved, such as councillors and technical departments.
What we are providing is an educational element that is applied right through the study.
Roger NARBONI
has given us some
comments on the
contribution made by
the lighting plan to the
way in which a city is
perceived at night.
What parameters have you included for the Bordeaux lighting plan ?
Using the 18th-century heritage of Bordeaux as a basis, we have applied the main
principles of public lighting for the boulevards, squares and courtyards. We have
compiled a “highlighting inventory” for the buildings that make up this heritage
(churches, towers, gates, etc.) and for not only the city centre but also the central parts
of the suburbs as well.
We have produced typologies for lighting, lamplight colours, colour rendering, the style
of street furniture to be implemented, etc.
Does the light designer have to take account of parameters linked to visual comfort such as problems of light pollution or light intrusion ?
Certainly. In Bordeaux, the steering committee also included the director of the
observatory, who is a member of an amateur astronomers’ association. He gave us a
fascinating insight into respect for the night sky and the nuisance that poorly-controlled
light can cause. We quickly acquired an awareness of this phenomenon, and the
designers paid close attention to it. The same can be said for issues of energy saving and
visual comfort. The schedule of conditions of the lighting plan obviously takes all these
parameters into account.

HESTIA µR
Hestia µR®: 240 units equipped with a µR® (micro-reflector). This luminaire, made entirely of aluminium and glass and designed by E. de Portzamparc, has opened up the way for
miniaturising optical compartments. Its elegant, compact design is based on the development of the µR® (micro-reflector), a reflector with high photometric performance and astonishingly small size that offers the lighting designer total creative freedom. This reflector
has been specifically developed for metal halide lamps with ceramic arc tubes (up to
150 W), providing excellent colour rendering.
SCHRÉDER ’s participation
in the lighting plan
for Bordeaux has led
to the supply of
a large amount of
equipment for
urban street lighting
and illumination.
Eden : 220 lanterns designed by JM. Wilmotte now light the Rue Sainte-Catherine, the
main pedestrian thoroughfare in Bordeaux. This luminaire, with its indirect lighting
— symmetrical or asymmetrical — offers a maximum of visual comfort. Equipped with
metal halide lamps with ceramic arc tubes (up to 150 W), it also provides excellent colour
rendering.
Its rear grille, which embraces the cylindrical cover, offers this particular design an unmistakable relief that is ideally suited to city centres.
CITEA
EQUINOXE
Equinoxe: 850 units (brackets and columns) equipped with Citea luminaires.
The Equinoxe sets, designed by JM. Wilmotte, are supplied on columns or wall brackets.
The conical cylinder columns, made of thermo-lacquered galvanised steel, position the
light sources 7-9 metres above ground level.
Citea: 600 luminaires installed on columns 4 metres high. This luminaire, designed by
JM. Wilmotte, is available in three models (Mini, Midi or Maxi) for power ratings of up to
400 W.
Kali: 100 luminaires, installed in the city’s squares. The Kali luminaire, also designed by
JM. Wilmotte, provides indirect lighting. It is equipped with an optical compartment
designed for metal halide lamps with ceramic arc tube (up to 150 W). The conical cylinder
column is made of steel or aluminium. The light source is positioned 4 metres above
ground level.
Floodlights of the Terra, Corus, Neos and Focal ranges have been used to illuminate
certain façades and monuments in Bordeaux. Schréder offers a complete range of
floodlights. Combining efficacy with mechanical robustness, they can produce all sorts
of light distribution.

What will be the economic effects in the city
of Bordeaux following the investment in the
lighting plan ?
It must be remembered that the investment was
not so very large - it is of the order of € 600,000
per year. In terms of the city’s image, it is an
extremely important investment. The Office of
Tourism fully understands the impact of the lighting
plan, and the tourism managers very quickly
produced a document featuring key spots in the
city by night. We welcome many students and
tutors, mostly from schools of architecture, and the
fascination with what’s going on in Bordeaux is
obviously contributing to the positive image that
the city is projecting at the moment.
What is the most positive effect that the
Bordeaux lighting plan will have ?
I am convinced that the light has helped improve
relations between people. The locals have
rediscovered their city; they have rediscovered
what is beautiful. And the beauty that the city
radiates thanks to its lighting also revitalises the
people who live there.

What contribution has the lighting plan made to the way in which the Bordeaux
cityscape is perceived ?
Before the project, there was a sort of global idea on the future of the city in terms of
lighting. But this idea focused rather more on technical aspects than on town-planning matters. The lighting plan is the fruit of an awareness on the part of the community, founded on true principles of urban development and on the need to keep the
city fully visible at night.
What are the performance criteria for the lighting, as accepted by the
technical departments in response to the lighting plan ?
The lighting plan has allowed a level of aesthetic coherence to be reached while
maintaining a preference for high-quality equipment. The technical managers were
concerned most of all with the photometric aspect, the efficiency of the luminaires
and the management of equipment maintenance. The use of high-quality equipment,
with completely tight optical compartments, has allowed maintenance services to be
kept to a minimum and the life span of the luminaires to be prolonged.
The first luminaires to be equipped with Sealsafe® compartments still look virtually
brand-new today. This makes us think that the original choice was a good one and
that we still have every reason to carry on selecting equipment of this type.
Ghislain luneau,
manager for New Light
Engineering Works with the
Technical Department of
the city of Bordeaux, gave
us his point of view on
the joint work carried out by
the various bodies involved.

Has the lighting plan led to any changes in the conception of photometry or of
“the mastery of light” ?
Today, mainly thanks to the lighting plan, we are looking to maximise luminous flux while
avoiding the problems of light pollution or intrusion. We are also looking to develop spaces on the basis of criteria that may be less conventional but are more connected with
creating an atmosphere.
What does the technical department think of the miniature reflectors
introduced by Schréder ?
It was indeed in Bordeaux that this new technology was tried out. Our city is one of the
first to feature the implementation of the µR® (micro-reflector). We have worked closely
with Schréder with a view to optimising and maximising the efficiency of this new tool.
It was the innovative effects on luminaire design thanks to this reflector that surprised
me most.

How did the idea of the Bordeaux lighting plan get started, and why did you enlist
the services of a light designer ?
In the beginning it was the wish of the Mayor himself, who suggested the initiative to the
city council. He was supported by a team that commissioned a technical committee to
meet with professionals and decide on choices. These professionals included an
architect, a town planner, a light designer, etc. They decided to launch a competition
based on a schedule of conditions.
Has Bordeaux played a pioneering role for other cities in the region ?
What is happening in Bordeaux may well give smaller towns or villages the desire to
illuminate fountains, washing places, monuments and so on. It makes such a difference
to the pleasant feel of a place! I think that a town that is well lit makes people want to go
out, to go and discover their town.

plan, this time from Mrs Josy
froment, who was in
charge during the
implementation of the
lighting plan at Bordeaux
Town Hall.
Has the lighting plan had an effect on security or added to the residents’ feeling
of security ?
Most definitely. Most people in Bordeaux believe that — following closely behind the
transformation of city properties and the return of the tram — the lighting project is the
most important thing that has been embarked upon in the city. Security, or a feeling of
security, is a key aspect of this feeling of well-being.
It should also be noted that the lighting plan projects were also discussed with district
councils and with residents. People are well aware that light makes it easier to move
about, reduces the possibilities for aggression, and so on.
They have had a real sense of participating in the revitalisation of their area through the
use of light. Light has created a dynamic of participation and conviviality.

CITY AND LIGHT
For some years now, light has been a tool used in the service of creativity. It is a field of
subjectivity that the light designer has to dominate. A city’s “lighting plan” is the
expression of this art form combined with the need to reconstruct the urban landscape in
the service of the people who use the city.
Schréder has come a long way since it developed its first luminaires...
Ready to listen to anyone who longs to give special character to a city.
It is this wealth of experience that has allowed Schréder to take up its position as a real
partner in city lighting projects.
And the fruits of this partnership can already be seen in many different cities across the
world:
