EDITORIAL 

Schréder News makes way for Schréder... 

Schréder Group GIE is delighted to present the first issue of Schréder. Up to now - and for many 

years already - we have brought you Schréder News. From now on, Schréder will be the official 

newsletter published by Schréder Group GIE. 

In addition to this change of name, there is also a new graphic style and a new, more practical 

and more readable format. In other words, this is a new information tool. 

The content has also evolved. While up to now Schréder News was mainly oriented towards the 

development of specific technical dossiers, Schréder will be more focused on what Schréder 

Group GIE is and what it does here, in your country, but also in the forty or so member companies 

located on five continents. 

Nevertheless, the technical dossiers will still feature in the newsletter. In this first issue, we will 

focus on the problem of light pollution, which is increasingly being looked at by the authorities, 

the public and... lighting manufacturers. Since Schréder aims to be the number one reference 

in lighting, this status must naturally be justified by fundamental research. The study initialised 

by Schréder Group GIE’s Research & Development centre on light pollution is just one such 

example of this. The quality of the luminaires and the quality of the photometric studies are the 

essential elements that will allow us to effectively tackle the problem posed by light pollution. 

Our products and research departments throughout the world are in a position to respond to this 

in an optimal way. 

For several years now, the Schréder Group has positioned itself as a partner of the city. 

Schréder is not only a manufacturer of lighting equipment. Schréder listens to all the players 

concerned with the future direction to be given to the city, whether they are town planners, 

lighting designers, architects or the local authority staff responsible for the regeneration of the 

urban landscape. 

And light plays a full part in this urban (r)evolution. Out of its functionality, it becomes the 

creator of ambiance. Light also provides orientation and guidance, it highlights and enhances, 

and aids perception and safety... In short, light is a formidable tool! A tool that Schréder knows 

how to control perfectly. To direct the light precisely where it is wanted and needed, with care and 

respect. Respect for people whose dwellings must not be troubled by intrusive light. Respect 

for the night sky that light must not obliterate. Respect for the world's energy resources, whose 

consumption can be limited through the use of high photometric performance luminaires. It is 

with this mission that we commit ourselves and devote our efforts. 

At your side. 

As partners. 

Happy reading!

LIGHT POLLUTION 

Report written by Jean-Charles Bogaert. Schréder Group Product Range Manager 

Light, a new source 

of pollution? 

After water and air pollution, should we now fear atmospheric pollution 

from light? A recurring theme in the debate on the future quality of 

our environment 

On a beautiful summer’s night, haven’t you 

often lamented the abundance of lighting 

preventing you from contemplating the 

Milky Way? An anarchic proliferation of 

advertising signs, a waste of energy and all 

sorts of pollution generated by badly 

designed public lighting... It’s a fact: badly 

used or excessive lighting can be a 

nuisance. Astronomers were the first to 

attract our attention to the problem, but the 

general public is also starting to make itself 

heard. 

In North America and Europe, committees are 

forming to demand that this problem be taken 

seriously. Astronomers are of course at the 

forefront of these demands, and in certain 

countries the authorities have passed laws 

regulating the use of lighting close to their 

observatories. The Czech Republic, Australia, 

the United States, Chile and Italy are also 

developing a legal arsenal against “light 

pollution”. And the United Kingdom could soon 

follow suit. However, the greatest caution is 

required if we are to avoid overly simplified 

laws that will only end up banning the most 

high performance equipment in terms of 

energy consumption. 

Light pollution or unwanted light? 

The word pollution refers to “damage to an 

area resulting from bad management of the 

environment or the introduction into this 

environment of pollutants (chemical, 

biological, urban or domestic waste)”. Is this 

a suitable definition for defining the problem 

4 I SCHREDER GROUP NEWSLETTER 

in hand? It is difficult to consider light in itself 

as a “pollutant”; it is rather an excess and 

bad use of it that makes it harmful. We would 

therefore prefer to use the term “unwanted 

light” to define a light that “attracts 

attention, is a source of bother and one we 

cannot escape even if we want to”. 

But is light always really the guilty party? 

Quite often, residents’ complaints focus on 

lighting for the sole reason that it is, by 

nature, very visible. In reality, the pollution 

attributed to it may have other causes, such 

as noise coming from a road, a car park or a 

sports ground. This problem should thus be 

approached in an overall manner, taking into 

account all its components, and in particular 

the surrounding area. It is clear that the 

problem cannot be resolved in the same way 

if the lighting installation in question is 

located right in the middle of a town centre, 

on the outskirts of a town or in a rural area. 

There is a hierarchy to be respected between 

these various sites. In certain sensitive areas, 

such as an airport for instance, lighting is 

major safety factor. 

Animals and plants as well... 

Unwanted light can be subdivided into several 

types of pollution for which it is necessary to 

find specific solutions. For instance, the night 

sky can be polluted by what is called a halo of 

light. This is caused by light emitted upwards, 

which illuminates the sky by reflecting on the 

particles suspended in the air (dust, water 

particles, etc.). 

A halo of light indicates the combination of 

two types of pollution: light emitted directly 

by the luminaire towards the sky - light 

shining directly upward - and light reflected 

by the surface to be lit - light reflecting 

upwards. 

The halo of light diminishes the contrast 

between the stars and the dark background 

of the sky, thus making it difficult, 

or even impossible, to make astronomical 

observations. In other words, it is not greatly 

appreciated by astronomers. Certain studies 

even aim to show that it could influence the 

natural cycle of animals or plants. 

Gefahr für die Augen ! 

Another type of pollution is dazzling light 

caused by too great a contrast between the 

light source and the surroundings. This 

generally happens when the light shines 

directly and too intensely into the eyes. By 

shining directly into the eyes, the light limits 

the eyes’ ability to adapt to the dark, thereby 

making dark areas dangerous. 

Finally, the last type of pollution is intrusive 

light caused by an excess of light diffused by 

certain lighting installations towards areas 

where lighting is not desirable. It manifests 

itself in different ways, such as for instance 

the intrusion of exterior light directed 

towards windows of houses, disturbing the 

sleep or activities of the occupants. 

The solution: efficient optics 

What are the factors that cause a halo of light 

and how can they be prevented? To find out, 

Jean-François Laporte and Marc Gillet of 

Schréder Group GIE conducted a study on 

photometric performance. 

Their study, based on 175 photometric 

readings, combined a variety of parameters: 

type and power of the light sources, light 

distribution of the luminaires, shape of the 

luminaire protectors, configuration of the 

road, and the road surface. Their method: an 

analysis of the upward luminous flux emitted

Unwanted light is characterised by several sources of 

pollution: dazzling light, invasive light and a halo of 

light, which indicates the combination of two phenomena: 

light emitted directed by the luminaire towards 

the sky - light shining directly upwards - and light 

reflected by the surface to be lit - light reflecting 

upwards. 

Invasive light is an excess of light directed towards 

areas where it is not desirable. 

directly by the luminaire and indirectly by the 

reflection on the lit up roads and their 

surrounding area. 

86,000 calculations to avoid systematic use 

In total, they made more than 86,000 

photometric calculations. They were in 

particular able to demonstrate the variations 

in the upward luminous flux depending on 

the road surface and its surrounding area. 

To reduce the dispersion of the luminous 

flux towards the sky, they recommended 

optimising the photometric performance 

and the location of the luminaires. They 

emphasised that the luminaires equipped 

with a flat protector are not systematically 

the most suitable as regards light pollution. 

Those equipped with a slightly curved 

protector are better in some cases. 

Consequently, no permanent obligation to 

use flat protectors! 

The secrets of a good luminaire 

In fact, we always come back to the number 

one question: optimising the optics. It is only 

by endeavouring to do so that we will be able 

to successfully prevent light pollution. The 

research carried out by Schréder has 

demonstrated the following: a good luminaire 

is one that manages to optimally use the 

luminous flux emitted by the lamp in order to 

precisely focus on the area to be lit. 

Luminaires designed for “precise lighting” 

should therefore be used. 

Precise lighting, against unwanted light 

and for sustainable development 

However, these “clean” luminaires not only 

make it possible to prevent unwanted light, 

they also allow for a reduction in the number 

of luminaires and the power of the lamps. 

The result: significant energy savings, which 

remains a major concern for sustainable 

development issues. 

Keyword: efficiency

Efficiency is the keyword to come out of this 

study. It is also the objective that Schréder 

has set itself within the framework of its 

Research & Development activities, and it is 

an objective we will undoubtedly achieve 

thanks to our photometric developments and 

our research department. It is these 

departments and this know-how that make a 

difference with regard to photometric

responsible for Schréder’s position as THE 

reference in lighting. 


FEATURE 


What are the different types of protector? 

Deep protector 

One of the main parameters the study 

takes into account is the shape of the 

protector: flat, slightly curved or deep. For 


Slightly curved protector 

each of these models, the quantity of light 

emitted upwards has been calculated by 

varying the type and power of the source, as 

Shape of the protector: 

no simplistic answer or systematic use 

With the deep protector, there is a significant luminous 

flux shining directly upwards towards the sky. But 

thanks to a large space between the poles - made 

possible by a better use of the lumens emitted by each 

lamp - there is a lower number of luminaires and a 

reduction in the reflected luminous flux. 

It is important to emphasise that a luminaire 

with a flat protector positioned horizontally 

is not automatically the best solution to limit 

the total luminous flux shining upwards. 

With the slightly curved protector, there is less 

luminous flux shining upwards towards the sky. 

However, because the space between the poles is 

smaller, the reflected light flux increases. 

This clearly shows that we cannot always 

recommend the same type of luminaire, and 

that the best solution requires a specific study 

that takes into account all the environmental 

parameters. 

Flat protector 

well as the nature of the road surface and the 

surrounding area. 

With the flat protector positioned horizontally, there is 

no luminous flux shining directly upwards, but because 

there is a smaller space between the poles, the 

reflected flux is greater and the total power of the 

installation is much higher. 

A compromise has to be found between the 

total installed power and the luminous flux 

emitted upwards. This depends on a great 

number of factors and requires a specific indepth 

study.

FEATURE 


This diagram shows that the total luminous 

flux shining upwards (direct and reflected) is 

directly proportional to the average number of 

lumens required to obtain the desired 

luminance on the road. This means that if we 

manage to reduce the number of lumens 

installed while maintaining the same level of 

luminance, the total luminous flux shining 

upwards will decrease proportionally 

regardless of the type protector. 

In short, it is therefore the photometric 

efficiency of the installation that will lead to 

a reduction in unwanted light. 

We have noted that with asphalt, the total flux 

shining upwards is reduced by half compared 

to when concrete is used. 

Furthermore, the flux shining upwards 

reflected by grass is more than halved 

compared with the flux reflected by grey 

paving. 

It is interesting to note that the road surface 

and the nature of the surrounding area are 

two significant factors which contribute to 

the reflected luminous flux emitted 

upwards.

Examples for inspiration 

Illuminating from the ground 

The Terra Maxi and Midi floodlights are the 

ideal tools for the upward lighting of façades, 

monuments, trees, etc. When equipped with a 

suitable reflector, it is possible to control the 

light without unnecessarily dispersing the flux. 

Photometric accessories on floodlights to guide the flux 

The new ranges of floodlights developed by 

Schréder - for instance, Focal and Neos - take 

into account the concern for precise lighting 

An old design is not an antique 

Integrating high-performance 

optics into an old-fashioned 

street lamp is possible. The 

optics direct the light with 

precision onto the place to be 

lit: road, path, car park, etc. 

while the optical compartment 

forms a watertight unit accessible 

via a plug. The Sealsafe ® system 

provides the luminaire with an IP66 

tightness level during the whole of 

its lifetime. This system prevents any 

accumulation of dust inside the

protector, diffusing the light in all 

directions. It remains clean and does 

not hinder the dispersion of the 

luminous flux, an advantage that also 

makes it possible to limit the 

power of the lamps since the 

loss of light is minimised. 

The use of louvres, a light channel or a visor make it 

possible to direct the luminous flux towards the area to 

be lit.

Solutions for lighting large areas 

Lighting for sports grounds or large areas 

(car parks, storage areas, airports, etc.) 

requires numerous high-power floodlights 

placed high up. 

The most simple solution would be to incline 

the floodlights so that the luminous intensity 

peak is at the desired angle, but this has been 

shown to cause light pollution. This is why 

Schréder developed Alisios, a highly 

asymmetrical floodlight that offers a 

maximum luminous intensity angle of 60° 

while maintaining the floodlight in a 

horizontal position, thus preventing a direct 

flux upwards. 

Urban luminaires respectful of residents 

The luminaires in the Citéa, Maya and Scala 

ranges can be equipped with louvres that 

limit invasive light directed towards housing. 

In this luminaire for lighting towns and roads, the louvres 

have been integrated into a Sealsafe ® optical compartment 

in order to limit invasive light directed at 

facades situated behind the luminaire. Their inclusion 

in the optical compartment prevents them from becoming 

dirty. 

FEATURE 


The Alisios floodlight aims to meet concerns regarding 

efficiency as well as limiting flux shining directly 

upwards.

Examples not to follow! 

Globes are a no-no! 

Globe-shaped luminaires devoid of any optical 

system whatsoever and shining light in all 

directions are a good example of what should 

be avoided under all circumstances! 

However, one-fifth of the decorative lighting 

installations in France are equipped with this 

type of luminaire. 

While “globe lighting” may be one of the classics when 

it comes to decorative lighting in our urban landscape, 

it is nevertheless a horrible source of unwanted light! 

Schréder has developed several luminaires inspired by 

this basic form by equipping them with high-quality 

optics that are more respectful of the environment. 

GENERAL GUIDELINES TO LIMIT 

UNWANTED LIGHT: 

[1] Make sure the floodlight receives regular 

maintenance and that the exterior surface 

of the protector is regularly cleaned. Dust 

can modify light distribution by increasing 

the overall diffusion of the light. 


[2] Do not “over-light” by respecting the 

existing standards as closely as possible. 

[3] Soon, electronic intensity dimmers will 

allow operators to precisely adjust the light 

emitted by a luminaire depending on the 

levels of lighting required. 

In the Canaries, the 

stars shine more 

brightly 

Wide open spaces, a clear sky nearly all year 

round, a very thin atmospheric layer...all these 

are conditions sought after by astronomers. 

Hardly surprising then that they decided to set 

up shop in the Canaries! And it is no surprise 

either that these islands are leaders in the fight 

against halos! 

In 1988, the Spanish government promulgated a 

law relating to the protection of astronomical 

observations, finalised by a royal decree in 

March 1992. An office for the protection of sky 

quality in the Canaries (O.T.P.C. - Oficina 

Técnica para la Protección de la Calidad del 

Cielo) was also created in January 1992. Its aim 

is to control and assess the various activities 

which could hamper observations. 

These laws (*) control both outdoor lighting and 

anything that could disturb the astronomical 

observations, such as industrial emissions, 

exhaust fumes from planes or radio signals. 

In particular, they specify that luminaires for 

lighting roads cannot be inclined and cannot 

emit light upwards. They must also be equipped 

with a double lamp system or a system to vary 

the lamp’s intensity allowing the luminous flux 

to be reduced after midnight by at least two 

thirds of the initial power, without having a 

negative effect on uniformity. 

The light from the floodlighting on public 

buildings, monuments and advertising boards, 

and light from the lighting in parks or sports 

grounds must always be emitted downwards. 

Furthermore, these types of lighting must be 

switched off by midnight at the latest. 

Nevertheless, social life does not appear to 

suffer from this drastic legislation. A list of 

authorised lighting devices has been 

established by the IAC (Instituto de Astrofísica 

de Canarias), and Schréder luminaires are 

among the most highly rated.

Atos 

A luminaire made from synthetic materials 

Atos is a new, recently developed luminaire for 

public lighting applications combining savings 

in capital costs and high photometric 

performance. This luminaire, with its assertive 

design, is almost entirely constructed using 

synthetic materials with obvious anti-corrosive 

properties. While robust in its design, Atos is 

nevertheless light in weight. The Atos 

luminaire offers a remarkable tightness level 

both with regard to the optical compartment, 

with the Sealsafe® system ensuring a longlasting 

IP 66, and the IP 54 control gear 

compartment. This luminaire, which is 

equipped with an inclination system, can be 

used in all types of environments.

An original design in outdoor urban lighting, 

the Abahjur luminaire is a fun element that 

helps to create atmosphere in towns. 

Abahjur can be equipped with a coloured 

protector and / or lampshade. It comes 

equipped with a metal halide lamp with a 

ceramic arc tube (coated elliptical) of up to 


150 W. The development of this new 

luminaire has particularly taken into account 

the necessity of limiting the dispersion of 

upward luminous flux. 

Abahjur is a totally new design for lighting town centres and is specifically designed to create a pleasant atmosphere. In 

white or colour, Abahjur clearly associates creative and functional lighting. 

Modullum 

A modular photometric 

column 

The Modullum columns are characterised by 

their flexibility as regards photometry based 

on the diversity of modular optical compartments. 

According to the type of environment 

and the size of the column (Micro, Mini, Midi or 

Maxi), it is possible to select a model with 1, 2, 

3 or 4 modules, each with a distinct photometric 

function: lighting avenues, pavements, 

foliage, roundabouts or urban signposting. 

Depending on the model and type of optical 

compartment chosen, Modullum can incorporate 

metal halide lamps with a ceramic arc 

tube and high-pressure sodium of up to 150 W, 

or compact fluorescent lamps of up to 18 W. 

Modullum is available in four sizes: from a luminous 

post to a big urban column 9.50 metres high.

BEKA in the domain of manufacturing poles 

in reinforced fibreglass, which optimises 

aesthetic aspects and presents a high degree 

of rigidity. 

The column has an optical compartment 

integrated into the top of the unit for a 150 W 

metal halide lamp. The optional translucent 

part of the column is equipped with a 100 W 

metal halide lamp. These columns are 

available in two sizes: 5.5 or 6.5 metres. 

The new South African constitutional court, as well as 

new tourism and cultural infrastructures, are located 

on Johannesburg’s Constitution Hill. It is on this 

prestigious site that our member company installed 

400 luminous columns.
