IT WAS ANOTHER brilliant fall evening
in Bonne Bay, Gros Morne National Park,
with the stars providing a potpourri of
sparkle. To the south, the silhouette of the
mountains, illuminated by the waters of
Western Arm, invited welcome relaxation and
contemplation. But tonight something was
amiss, the tranquility ruptured. Sharp shafts
of white light pierced the evening sky: the
harsh light that of a recently opened Inn – a
place developed to allow visitors to enjoy the
splendor of this marvelous place. Such irony!
I thought. Surely we can do better!
Indeed, light polluted skies are ubiquitous.
Since Mr. Edison’s bulb turned Chicago into
the “white city” at the World’s Fair in 1893,
our cities have become increasingly “white.”
Today, the light from large cities is visible up to
one hundred miles away, and it affects about
60 per cent of our world’s people and about
one-ﬁfth of the world’s terrain. We are led to
believe that new lighting technology uses less
energy and is environmentally friendly, so we
use more lighting and think it’s safe.
Yet we are compromising our existence
as diurnal creatures, according to Verlyn
Klinkenborg, author of the National Geographic
article, “Our Vanishing Night.” We’ve
engineered the night to receive us by ﬁlling it
with light, yet much of that light is wasted.
Light pollution represents an estimated $2
billion per annum in lost energy, even if we
ignore its impacts on human health and the
The Dark Sky Association categorizes
light pollution as Clutter, Glare, Light
Trespass and Urban Sky Glow. “Clutter” is
bright, confusing and excessive groupings
of light sources, commonly found in over-lit
urban areas. “Glare” is excessive brightness
that causes visual discomfort. “Light
trespass” is light falling where it is not
intended, wanted or needed. “Urban sky
glow” is the brightening of the night sky
over inhabited areas.
Today, rather than identifying a light
bulb according to the power it consumes,
lumens identify a light bulb’s perceived
brightness. Dark Sky ordinances limit
the lumens (luminous ﬂux) per acre, and
ensure streetlights are shielded to focus
light downward, to make streets brighter
but the sky darker. This strategy, and
other new planning and design approaches
for neighbourhoods can help control the
misuse of light.
There are many inventive solutions to
explore: for example, research conﬁrms
that good planting design on city streets
can reduce glare and increase visibility –
and this is just one informative nugget
that can be shared with our clients. The
emerging role of landscape architects,
then, is to offer information and creative
options to their clients and communities, to
use lighting design professionals, and to be
in the forefront of inclusive lighting design.
