*****News Flash***** The Strathfield Council draft Vision
received more submissions on the issue of light pollution than all
other issues combined thus highlighting the great concern felt by the
community regarding the environmental and human health impact caused by
the recent exponential growth in the amount of polluting night time
outdoor lighting now spilling unchecked into the night sky. Well
actually....there were not any other submissions at all. What an
apathetic lot we are! (2 July 2005)

the back of the centre seems to be to attract the attention
the passing traffic. The glare which they produce would be
illegal if they were car headlights. There are
units directly across the road from these which would suffer
considerably from light trespass!
Catholic University, Strathfield Campus.
The car park of the ACU in Strathfield is filled with dozens
totally unshaded high brightness lights of the glass globe
variety set on high poles. These lamps shine more than one half of
their light output directly into the sky above. Not only is this
illumination of the sky completely useless, it is a considerable waste
of energy (and money). It contributes considerably to the
pollution of the night sky and thus helps to deprive residents of

Unfortunately, it is lit at night by three high power spotlights facing
directly up into the sky from the base of the flagpole. This is in

They would also be considerate
citizens if they were to take the flag down at sunset, thus avoiding
the need for the energy wasting and polluting spotlights. Perhaps they
are too lazy; but probably just ignorant of the effects of light

of the mercury vapour lamp
The mercury vapour lamp is still probably a second best choice. It is
not the most efficient lamp available and it emits strongly in the blue
end of the spectrum. Blue light is the worst form of light pollution
since it has a greater deleterious effect on human health and is more
of a problem for astronomical observatories than other parts of the

Has Become a Public Health Issue.
Dr Stephen Pauley, a retired
has written a paper on health issues of light at night.
The hypothesis that
suppression of melatonin (MLT) by exposure to light at night (LAN) may
be one reason for the higher rates of breast and colorectal cancers in
the developed world deserves more attention. The literature supports
raising this subject for awareness as a growing public health issue.
Evidence now exists that indirectly links exposures to LAN to human
breast and colorectal cancers in shift workers. The hypothesis begs an
even larger question: has medical science overlooked the suppression of
MLT by LAN as a contributor to the overall incidence of cancer?

Observatory Hill on 25 July 2005. Note the glow in the sky just above
the bridge. Within this glow there are some squiggly white lines which
were produced by birds flying within the upward shining light beams on
this 15 second exposure. These birds are either attracted by the lights
or are feeding on insects which have been attracted by the lights. The
bridge floodlights are turned off at 1:00am.
