Rights to light challenged
Last month the Law Commission
began a ministerially backed threemonth consultation on the legal
entitlement to daylight.
Dating from 1611, ‘rights to
light’ are automatically prescribed to
buildings where natural light has been
constant for 20 years, a situation the
consultation is proposing could be
changed. The move is part of the
continued bid to free up planning
laws, and to prevent home owners
delaying development projects.
According to the Consultation
Paper, the YPNO[[VSPNO[PZKLÄULK
as ‘an easement: a property right,
entitling a landowner to receive,
usually through a window, enough
of the natural light passing over a
neighbour’s land to enable the
ordinary use of the building’.
Some 2.8m homes in England
and Wales built in the past 20 years
could be affected if the automatic
right is removed.
‘Rights to light can have a

ILP launches Skills Portal
The ILP is to launch its new Skills

together the training and education
resources already offered by
manufacturers so that a wider
audience of young lighting designers

required skills and identify where
training resources are available.
‘It is designed to help practice

programmes, and for young entry-level
designers to understand what they
need to know and help them acquire
the necessary skills and knowledge,’
said ILP vice president Mark Ridler
(pictured), who has been instrumental
in organising the portal.
To get involved, manufacturers
simply need to provide a 30-50
word summary of what training
they offer, and what they will
provide, as well as a contact
that designers can use to
arrange training. This will allow
designers to approach providers
directly as they wish.

The findings of an important research paper on
lighting and traffic accidents will be the subject
of an online live seminar on 2 April. The webinar
has been organised by the Lighting Research
Centre (LRC) at Rensselaer Polytechnic Institute
in the USA, in conjunction with the ILP.
Entitled To Illuminate or Not to Illuminate:
roadway lighting as it affects traffic safety at
intersections, the session will feature LRC
director and professor Mark Rea and senior
research scientist John Bullough, collaborating
with Eric Donnell, associate professor at Penn
State and faculty researcher at the university’s
Thomas D Larson Pennsylvania Transportation
Institute. All of them were involved with the
research project.
The team used lighting and crash data
for state highway intersections in Minnesota
to develop quantitative models relating nighttime driving safety to the presence of lighting
at these intersections.
In parallel, LRC researchers modelled
prototype roadway intersections with and
without lighting, based on roadway lighting
practices in Minnesota, and including the
effects of vehicle headlights.
Using a model of visual performance
developed by Rea while at the National Research
Council of Canada, they were able to estimate
drivers’ ability to detect potential hazards quickly
and accurately under each lighting scenario
compared to when there was no roadway
lighting present.
According to LRC, the webinar will offer
information that can be used now to not only
allocate lighting more efficiently, but to design
lighting more effectively.
‘As new practices such as solid-state
lighting, adaptive roadway and vehicle lighting,
and benefit-cost analysis continue to emerge,
the tools that will be presented in this webinar
will help agencies specify and shape lighting
that minimises energy use and environmental
impact, while maximising the use of limited
public resources,’ said Rea.
The webinar is on 2 April at 5pm and will
last one hour. Cost per participant is $25
(around £16), free for LRC Partners. Sign

LETTER
The recent ILP Forum on S/P ratios was an
excellent event; I was honoured to have been
invited to attend and hope that the ILP continues
to hold such events. There is a need though to
address a critical item raised in the brief summary
presented in the January 2013 issue of LJ, and
this relates to energy consumption.
The summary mentions that the new
guidance based on S/P ratios will lead to an
increase in energy consumption, this being
relative to previous guidance which allowed a
one-step reduction when using white light.
This is not a fair statement.
What the new guidance (as reported in
PLG03) does is provide a system that maintains
approximately the same level of visual amenity
under different types of lamp by allowing variation
in illuminance – a lamp of higher S/P ratio uses
a lower illuminance. With lamps of moderate S/P
ratio this reduction in illuminance may not be as
much as gained using the one-step reduction, but
it is still a potential energy reduction compared
with no reduction in illuminance.
The one-step reduction used only one
criterion, that lamp Ra was equal to or greater
than 60. Colour rendering (Ra) says nothing about
ability to detect pavement obstacles, potential
trip hazards. So ignoring S/P ratio (which does
Lighting Journal March 2013
correlate with obstacle detection) might have
led to a compromise on safety when using lamps
of high Ra but low S/P ratio by using a low
illuminance when it was not justified.
On a larger scale, a switch-off policy saves
energy but is recognised to be disadvantageous
for safety, yet we do not refer to the increased
energy consumption of a non-switch-off policy.
Let’s be consistent with compromises.
The aim of guidance offered in PLG03 is
to maintain equal visual amenity under different
lamps: what it does not do is to say whether
that is the right level of visual amenity, because
that is a function of illuminance class selection.
It is in the selection of illuminance class that
energy consumption is primarily addressed, yet
there appears to be little evidence for this range
of illuminances in either visual needs or costbenefit analysis.
My contribution to the Merlin project, along
with Peter Raynham at UCL and John Barbur at
City University, is working towards generating
better data for the selection of lighting classes.

Chinese and American researchers claim to
have created an LED lamp that emits warm
white light – less than 4000K –with a single
light-emitting phosphor, according to findings
published in the online journal Light: Science
and Applications.
The usual process of combining two
or more phosphors to achieve warm white
light from LEDs is costly and often results in
inconsistent colour output because the source
materials respond differently to temperature
variations. A single phosphor theoretically
solves the problem of colour stability because
the colour quality doesn’t change with
increasing temperatures.

CALL FOR PAPERS
11 & 12TH SEPTEMBER
Left to right: Feng Liu, Zhengwei Pan and Xufan Li
(University of Georgia)
physicist Zhengwei Pan, with colleagues
from Georgia, Georgia Southern University,
Oak Ridge National Lab, Argonne National
Lab, and the Chinese Academy of Sciences –
created the new phosphor by combining small
quantities of europium oxide with aluminium
oxide, barium oxide and graphite powders.
They then heated the powders at 1450
degrees C in a tube furnace. A vacuum
created in the furnace pulled the vapourised
materials on to a substrate, and deposited the
vapours as a yellow luminescent compound.
This compound was then encapsulated
in a bulb and illuminated by a blue LED chip,
creating a warm white light. The phosphor
material achieves a colour rendering of Ra85.
‘Our material,’ says Pan, ‘achieves a
warm colour temperature while at the same
time giving highly accurate colour rendition,
which is something no single-phosphorconverted LED has ever been shown to do.’
However the process is still not
commerically viable as the efficiency of the
new material is much lower than that of
conventional white LEDs. In addition,
in order to produce it on an industrial scale
means resolving even small variations in
temperature and pressure in the phosphor
synthesis process which can result in
materials with different luminescent colours.

LIGHT Minded...
Frustrated lighting designer Kevan Shaw, principal of KSLD,
writes an open letter to LED marketeers
D
ear LED marketeer: I think you are
not really aware of where LEDs are
or should be at in 2013. From my
experience, generation one was the
5mm epoxy encapsulated white LED that
I specified on to projects around 1999 to
2000. Generation two was the first highpower devices from the likes of Lumiled,
Cree and a few others. Generation three
was the wafer-thin flip chips when we
started to see some reasonable, genuine
light output and efficiencies. Generation
four is the remote phosphor devices where
the possibility of reasonable and reliable
colour rendering appeared.
We are, after some 13 years, still waiting
for Generation X: the LED with a guaranteed
long life, genuine high efficiency in the
application including all gear and optical
losses, excellent colour rendering, good
warm colour appearance and able to deliver
a clean tight-focused beam of light – in fact,
exactly what has been promised by LED
marketeers like you since 1999.
We also need these at an initial cost
directly comparable with other light sources
because most lighting equipment purchase
decisions end up being made on, or
excessively influenced by, purchase price.
Your assertion that traditional luminaires
are ‘seriously inefficient’ is not correct. It
is convenient that the standards for LEDs
require complete fittings to be measured so
the light output ratio is always 100 per cent.
All optics have losses, all LEDs have very
significant efficiency losses due to operating
temperatures (it took 10 years before the
practice of quoting LED efficiencies at a
junction temperature of 20 degrees C began
to be changed to something closer to actual
operating temperature). By normal standards
the most efficient luminaire is a bare-batten
fluorescent where all the light except for that
reflected from the batten spine is available
to be directly reflected by room surfaces,
thereby creating a luminous environment.
LEDs, by their nature a directional light
source, may be better at delivering light
into a small patch below the fitting and this
is historically how lighting has come to be
measured, though it is not the most effective
way of creating lit space. I would direct you
to Christopher Cuttle’s papers on ideas for
how to advance lighting design and light
measurement to see where things need
to be going in this respect. Quality of light
is about the quality of the lit environment,
not any numbers relating to any particular
performance parameter of the fittings used.
As I mentioned, LEDs are typically
directional. However, when it comes to
really narrow distributions, say to use
instead of LVTH reflector spotlights, we
still cannot get good clean beams below
20 degrees. What we get are multi-chip
devices with consequent multiple shadows
and single-chip devices with a fried egg
distribution – a hot spot more or less of the
required beam angle with a huge blob of
light out to the field angle which is three
or four times the beam angle when it
should be very close to it.
To tame the good remote phosphor
LEDs into a decent beam requires reflectors
of 125mm diameter or more, giving lie to
the claim that LEDs allow for small fittings,
particularly once you have added the
requisite massive heatsinks.
Directional lighting is a limited subset of
the tools required by lighting designers. Area
lighting by LEDs is frequently possible but
at astonishingly high cost. Typically a lensed
linear fitting for close offset wallwashing will
cost £700 a meter and has the advantage of
being able to work at a very close offset. The
energy cost is usually around 70W a meter
for 2W chips on 33mm centres.
Doing the same job with fluorescent
would use a 1.2m-long 28W fitting end-toend, albeit at a reasonable offset from the
wall, with a range of fittings priced between
£80 and £300 each. To be frank, the quality
of light available from good T5 tubes is
comparable with typical LEDs both in the
warm and cool range. The chip-on-board
type devices suitable for linear applications
like this just do not come in really good
colour rendering types.
You seem to have convinced a great
many non-lighting specialists that LEDs
are the only light to be used now and in the
future. How about using this expertise to
persuade your company bosses to actually
deliver what you have promised?

I saw the cars moving along this

of LCADS summarise the key
points in the ILP’s latest
guidance, PLG04
PLG04 Guidance on Undertaking Environmental Lighting
Impact Assessments has been produced primarily as a
working guide to lighting assessment procedures, where
required within planning applications. However, as it is based
on the fundamentals of good lighting practice, it should also
help designers in evaluating lighting effects in many other
situations. It has developed into a fairly long document and
its main sections are summarised below.

assessments, the situation can occur in a variety of
environments, each of which will have its own characteristics.

Section 1: Background
Describing and characterising both rural and urban
environments has been a function of landscape architecture
for many years. Originally, there was little consistency in
style or scope of coverage, including lighting aspects.
Eventually, methods became more formalised and
incorporated in national regulations, requiring both details
of any changes associated with developments and
assessment of their impacts.
Environmental Impact Assessments (EIAs) became

Mike Simpson reviews the SLL’s
latest guidance on obtrusive light
P
eter Boyce, the author of the SLL’s Guide to limiting
obtrusive light, is a well-known academic in the lighting
profession, and brings together both research and
practice to the guide, making it a one-stop shop for all issues
relating to obtrusive light. For those for whom this is a new
[VWPJ[OLKLÄUP[PVUZVM[OLKPMMLYLU[ZV\YJLZVMVI[Y\ZP]LSPNO[
– sky glow, light trespass and glare – will be useful. The guide
then goes on to look at the science behind these.
For sky glow, the mechanisms of light scatter are

the horizontal. Understanding these principles will enable the
designer to choose the correct equipment and apply it in such
a way as to minimise sky glow.
The mechanisms of glare are also discussed and, although
later on limiting intensities are quoted, I always have the feeling
that any source against a night sky is going to cause some
objection and, with something so subjective, is this the best
way of controlling it?
Practical measures to
restrict a direct view
of the source from a
distance may well be
the best approach.
The meat of the
guidance is in the
section on lighting
limits, where the
lighting designer can

One way to limit obtrusive light, of course, is to keep
lighting levels to a minimum, and reference is made to
reducing designed levels with white light sources. This
technique has now been fully embraced in BS5489 2013

we now consider the shift in the eye’s response towards the
blue end of the spectrum.
Other things to consider are mechanical shields to reduce
the effect of glare, and controls on when the lighting is to be

collection target, which is currently 4kg per inhabitant, will
be increased to 45 per cent, calculated as a percentage
of the average weight of EEE placed on the market in the
three preceding years.
The UK already collects 7.9kg per inhabitant. Calculated
using the new method in the recast directive, in 2011 this was
equivalent to around 32 per cent, averaged across all sectors.
So the 45 per cent target is a material increase.
Also from this date, photovoltaic panels will come on to
the radar. Then, from 2018, the scope of the regulations will
change to what is known as an ‘open scope’ principle. This
means that instead of listing all of the equipment that falls
^P[OPU[OLZJVWL[OL>,,,+PYLJ[P]L^PSSSPZ[PUP[ZHUUL_LZ

the equipment that does not. Inevitably this will bring a
great deal of equipment into scope that is not currently
included – such as switchgear, internally illuminated signs
and household luminaires.
From 2019, the minimum collection rate to be achieved
annually will be 65 per cent of the average weight of EEE
placed on the market in the three preceding years, or 85 per
cent of WEEE generated.
To enable the UK government to achieve this massive
increase in collection rates, we need to play our part in
ensuring that all of our WEEE passes through approved
recycling and reuse systems and that it does not magically
change into pocketed cash.
One way to address this problem, is for highways
authorities to require their contractors and their subcontractors
to account for all of the WEEE. Where waste street lighting

thereby enabling the authority to make a rough check on how
much magic has intervened between cup and lip.
It’s not just the disposal of street lighting lanterns that
needs scrutiny. Disposal of many other types of equipment will
fall within the remit of the local authorities, so we advise them
to check suppliers’ compliance status and ensure that they
belong to a compliance scheme that has a fully functioning
disposal infrastructure. Where authorities have lamps that
need disposal, Recolight, the compliance scheme for the
lamp industry, offers a free-of-charge collection and recycling

which also has a fully functioning disposal infrastructure

pass all of the WEEE to a compliance scheme for sound

In the grand scheme of things, 2016 isn’t all that far
away so it makes sense to start planning how the new
requirements will be addressed in projects. Again, one
obvious measure is to ensure that any electrical equipment

‘We’re seeing a general
trend of excessive
lighting and signage
which intends to give

Sir Andrew Motion, now president of the CPRE,
recently launched the Star Count 2013 campaign
with the following article in The Telegraph

ill Bryson, my predecessor as
president of the Campaign to
Protect Rural England (CPRE),
once said, ‘Glance at the night sky and
what you see is history, and lots of it.
Our faithful companion the North Star
appears not as it is now, but as it was
when its light left it some time during
the early 14th century.’
If watching the stars is the
closest we can get to time travel,
then a campaign to raise our sights to
what is above us, and to combat the
light pollution that increasingly robs
us of our celestial views, is all the
more vital. And so I am delighted that
The Daily Telegraph is supporting
Star Count 2013.
For me, dark skies are so important
for the inspiration they provide; artists,
philosophers, scientists and poets
have all found a muse in the night sky
for millennia. On a spiritual level, the
darkness of the night sky pulls at two

private universe. In our risk-averse
culture it does us good to remember
our place in the natural world – the
vulnerability of humanity – and the
power of darkness only adds to our
sense of what beauty is.
Loss of light forces us to slow
down and look closer, creating a more
powerful engagement with nature.
Wordsworth recognised the pleasures
of the moonlit ramble, where ‘at the
dead of night’ even the discovery of a
hedgehog becomes a ‘small adventure’.
So we too must learn to embrace the
darkness; the thrill of escaping from
cosseting health and safety, discovering
City Lights: International Dark-Sky association
the sounds and smells of the night
with heightened senses.
The tranquillity of darkness is
perfect for contemplating the ancients
who drew so much from the stars.
Far more recently, our own greatgrandparents would have enjoyed this
close relationship with the night sky,
perhaps traipsing through crepuscular
landscapes to gather corn under a
harvest moon.

closer to his life’s inspiration – skyscapes of dusk, twilight and pulsing

where the beauty of the night sky – the

– afforded deeper connections to life,

1926, Griggs maintained the link from
Palmer and the Romantics to the early
environmental movement.
Fitting too that CPRE should
become the leading defender of
our dark skies; our satellite maps of
England’s light pollution illustrating the
march of industrialisation which has
continued, unrelenting, since Palmer’s
time. Between 1993 and 2000, CPRE
data showed that light pollution
increased by 26 per cent, and only
11 per cent of the country had truly
dark skies by the turn of the millennium.
As lighting has become cheaper and
more powerful, it has blazed forth
from increasing numbers of roads, car

gardens and driveways.
If you still have a good view of
the stars, you are almost certainly in
the countryside. But even there it is
ILJVTPUNKPMÄJ\S[[VLZJHWL[OLVYHUNL
skyglow from nearby towns and roads,
and the security lighting increasingly
spilling from homes and developments
in rural areas. Light pollution is blurring
the distinction between town and
countryside, like a veil of light spreading
out across the night sky.
There is no doubt that, in many
places, good lighting is needed.
But we’re seeing a general trend
VML_JLZZP]LSPNO[PUNHUKZPNUHNL
which intends to give the perception

Because of the recession, councils
have been reducing street lighting since
2007 in order to save money. In 2010,
Leicestershire’s director of environment
and transport launched their ‘switchVMM»L_WSHPUPUN[OH[ºL_WLYPLUJLMYVT
other councils which have already
switched off lights shows that neither
accidents nor crime increase and, in
some areas, anti-social behaviour can
decrease, as it makes certain areas less
attractive to hang around’.
Research last autumn by The
Telegraph showed that all of England’s
27 county councils have dimmed or
switched off street lights in their areas.
At the same time, the government
published statistics on road fatalities
in 2011 showing that they were one
third lower than the average number
of fatalities between 2005 and 2009.
The accompanying statistics on
contributory factors listed the 76 most
common causes of road accidents –
an absence of street lighting was not
among them. There are arguments that
street lighting may even encourage
motorists to speed up, while reducing
their concentration.
Where crime is concerned, what
could be better than a halogen security
light to show a thief what is on offer?
Turning off suburban street lights in
Saffron Walden almost halved crime
rates, while numerous studies and

The really encouraging news is
that darker skies are within our reach;
improving technology means it is
increasingly easy to ensure that light
is directed only where and when it is
needed, and at the optimum intensity.
And that, combined with the growing

There were encouraging signs in last
year’s Star Count, which showed that
[OLU\TILYVMZ[HYNHaLYZL_WLYPLUJPUN
severe light pollution had fallen to
53 per cent, down from 54 per cent
in 2007’s survey. A note of caution
came from Bob Mizon of the Campaign
for Dark Skies – our Star Count partner
– who reminded us that ‘only one per

suggest they had a truly dark sky’. But
we need more people to join in to make

will help our campaigners work with
‘Darkness in itself
is not dangerous;
whether we are
walking, cycling or
driving in the dark

the government and local councils to
improve national policies and implement
practical schemes to reduce it. Around
the country, CPRE’s county branches
have already been working with local
councils and businesses to introduce
LULYN`LMÄJPLU[KV^U^HYKMHJPUN
lights. It seems the only thing that
could halt this admirable progress is
the reckless weakening of the planning
system, which could allow more urban
sprawl and new development in open
countryside. Where buildings and roads
go, light follows.
Our Star Count project will help
pinpoint the areas that need to do
more to reduce light pollution. And this
isn’t just about pressuring decisionmakers, it is about changing our own
attitudes towards wastefulness and
‘health and safety’. We all need to
switch more lights off (or use less
powerful ones) and we all need to
question pointless lighting.
Apart from monitoring negative
effects, we hope that Star Count 2013

The patented waveguide
technology offers distinct
advantages over other LED
manufacturers as it allows
the company to replicate the
light quality and uniformity of
traditional lighting.
MHA also use acrylic rods to amplify
and control the light output,
reducing the number of LEDs
required. This means they can use
high power LEDs, draw less current
and have no need to diffuse the
output.
Award-winning lighting company is leading the
way when it comes to slashing energy usage
and lowering carbon emissions.
MHA Lighting, based in Greater Manchester, uses two-thirds
of the energy of its closest competitors and has developed
bespoke light fittings for a variety of clients from both public
and private sectors.
Most recently, MHA Lighting provided a powerful solution to
replace lights at Bournemouth Airport car parks, with their
energy efficient P 30 fitting, which is just 67 watts inclusive of
ballast.
MHA’s installation provides a useful lifetime of 18 years and
is able to significantly reduce the airport’s lighting energy
consumption from 164,776kWh to just 46,137kWh, ensuring
they keep their carbon neutral ground operation status.
The new light fittings now installed in two of Bournemouth
Airport’s car parks use 72% less energy than the pre-existing
system. With the use of intelligent controls the P30 fittings will
save the airport an additional 25% on their energy bills by
reducing operating hours to nine from twelve.
The newly installed P30 fittings run maintenance free for the
duration of their 60,000-hour lifetime, providing additional
savings of over £1,000 per annum, as no operational
maintenance costs will be incurred.

of the new lighting scheme for
Durham cathedral concludes the
three-year project to upgrade the lighting
for both this landmark and the adjacent
castle, which together form a World
Heritage Site (see Lighting Journal June
2012 for details of the castle scheme).
The schemes, designed by Stainton
Lighting Design Services, were originally

cent to 80 per cent. Fittings have
been discreetly located and light
spill minimised. A key ecological
consideration was not to disrupt the
feeding habits of a local colony of bats.
While warm white (3000K) sources
were used on the castle, the cathedral
scheme has predominantly neutral white
(4000K) sources, with 3500K on the
buttresses. This was to ensure a link
between the castle and cathedral,
with only a subtle change
to differentiate between
the two buildings. ‘We

Future concept
Post modernism
A young architect with a radical
new use for the street light
There is no doubt that street lights have
become more multi-functional over
the years, supporting illumination for
pedestrians as well as roads, signage,
IHUULYZHUKÅV^LYIHZRL[Z;OLYLPZ
even the possibility of them becoming
charging points for electric cars.
But acting as a supporting structure
for housing for the homeless is a bit
VMHSLHW;OLJVUJLW[,_JYLZJLU[
Utopia, is the brainchild, if that’s the
right word, of Milo Ayden De Luca,
who began working on the idea after
completing his architecture degree at
the University of Greenwich.
Triggered by his increasing
awareness of the plight of the homeless
when travelling into central London in
the early hours, De Luca came up with
the idea of creating tensile structures
around street lights using cheap, basic
materials such as poly-laminated nylon
‘The form of
these spaces
is arranged
within the
geometric
parameters
to address
factors such
as intruding
light’

through this skin, subdividing the space
into smaller areas.
The temporary dwellings are
designed to be as lightweight as
possible so that they can be easily

LU]PZHNLZ[OH[OVYPaVU[HSIV_LZ^V\SK
WYV]PKLZSLLWPUNHUKYLSH_PUNHYLHZ
while vertical spaces would be for
activities such as busking.
The inspiration for the design comes
from the construction of sailing ships,
particularly the sails, pulleys and ropes,
for their ‘transparency, weightlessness
and movement’.
The idea begs quite a number
of questions, one of which is, won’t
the street light fall over? After all,
columns are purposely not very deeply

of collisions. This is where the ship
analogy comes in, as the structures are
tethered to surrounding buildings and
other street furniture using guy ropes,
cables and clamps.
Another issue is, won’t the lights
keep the temporary residents awake
at night and possibly interfere with
their biorhythms? However De Luca
has thought of that.
‘The form of these spaces is
arranged within the geometric
parameters to address factors such as
intruding light,’ he told LJ. ‘The space
for sitting is arranged to be offset and
below the source of light, with the user
facing away from it to reduce the need
MVYL_JLZZP]LZJYLLUPUN
‘In combination with this,’ he adds,
‘the poly-laminated nylon skin – which

to divide the spaces, but strategically
to provide adequate screening, diffusing
the harshness of the light, while still
allowing enough through the layers of
skin to enable the user to perform
the activities he or she requires within
the alloted space.’
De Luca is currently hoping to raise
funds to build a 1:1 scale prototype of
the design.

he arrival in London of an
international group show of
some 22 lighting artists is
very welcome. In the UK, at least,
recognition of lighting artists by
mainstream art institutions has been
begrudging, despite the fact that works
using light as their primary medium
now bring visual interest and wonder
to many a private and public space.
However, one grouse one might
reasonably have with Hayward curator
Dr Cliff Lauson is that while some halfdozen UK artists are present, better
known Brits such as Ron Haselden and
Martin Richman didn’t make the cut.
The last show in this mould at the

show too features a couple of his
works, rather gesturally tucked away

James Turrell, who occupies one of
several large, dark rooms with the

of the weaknesses of this show: its

some of which hardly deserve the

Moonlight (2009) – a nice, one-shot

to play with chromatic aberration but
it didn’t do it for me.
One work which does creatively
mine our perceptual confusion, and
which is one of the hits of the show,
is Chromosaturation (originally 1965)
by veteran Venezuelan Carlos CruzDiez, who hits 90 this year. His space
is divided into a trio of rooms, with a
transitional space across their open

The work plays intriguing havoc
with your vision, as you enter the
spaces in turn or stand at the
threshold and glance at all three.
Due to saturation effects, your colour
perception shifts constantly, so the

Two other successful works
given their own rooms are Conrad

more meaningful measure of the effective illuminance
of light sources under low light level conditions. The
measurement of S/P ratio is called for in the latest BS

were measured and Colquhoun was
surprised to discover that all the

engineers, manufacturers and research
scientists were CC Paterson (who

members of the subcommittee and
representatives from the British
Engineering Standards Association itself.
Opening the conference, Colquhoun
had to devote his opening address,
not to the potential success of the trial
installations, but to the many problems
and inconsistencies he’d discovered.
Along with the general issue of
NSHYL^LYLL_HTWSLZVM[OL]HYPLK
performance of the installations which
should have been constant and
uniform. It was odd that Colquhoun
chose to emphasise these defects
because delegates were going to
inspect the installations themselves. But
perhaps he drew these inconsistencies
to their notice, hoping that someone in
the learned audience could pick up on
a mistake or propose a solution.
The delegates were ferried from
street to street by motor bus where they
were met by Dr JWT Walsh and WS
Stiles (of the NPL) who had compiled a
small questionnaire and series of tests
(using special contrast-discs) to evaluate
glare. Progress around the 50 streets
was slow, with members keen to take
photometric readings and judge the
effectiveness of the lighting themselves.
Most didn’t make it back to their hotels
until the small hours of the morning.
The bleary-eyed discussions

would have been damning. The glare
calculations didn’t appear to work at
all as all the installations passed the
ZWLJPÄJH[PVU»ZYLX\PYLTLU[Z"ZVTL
installations were so poor that they
shouldn’t have been allowed within its
parameters; while some gave the same
readings of minimum illumination, some
were noticeably better than others; and
some gave intolerable glare but became
acceptable, even good, when the
wattage of the lamps was decreased.
Was it the distribution of light? Was it
the gradient of the road? Was it the road

brightness was being openly discussed
and even the phrase ‘silhouette effect’
appeared in Colquhoun’s address. The
association put on a brave face with
Colquhoun unconvincingly summarising
that minimum illumination was a useful
empirical measure if nothing else – or he
was aware that most of the architects

and that something should be salvaged.

the distinction between discomfort
and disability glare), and a young

delivered a paper which outlined a
possible new solution to this street
lighting problem.
