IMPROVEMENTS TO PUBLIC LIGHTING
New techniques in lighting are being studied by traffic engineers
in an effort to improve the standard of street lighting in Hong Kong.
One of the aspects under consideration is a technique knÓW11
as high mast lighting. This involves the use of clusters of powerful
lights, similar to flood lighting, suspended from poles up to 90 feet
above the road surface.
At present the maximum height for the mounting of street
lighting in Hong Kong is 35 feet.
A spokesman for the Public Works Department said today that
high mast lighting is more effective in illuminating intersections
where an even intensity of light is required.
To keep abreast of latest developments, a lighting engineer
with the P.17.D., Mr. Chow Ping-wai, has been sent on a nine-month
attachment to the City of Glasgow Corporation to study new public
lighting techniquca.

The spokesman said that other measures which are now being
implemented to facilitate both road traffic safety and public security,
include the installation of improved mercury and sodium vapour lamps.
These are being installed along all major traffic routes and
at road junctions in the urban areas.
In rural areas, the sodium lamp, which has a high light output
without producing glare characteristics, is more widely used.
