• The intensity of the white light is 116,000 Candelas
(CD) and can be seen for a distance of 20 nautical miles(32kms).
The red light has an intensity of 23,000 CD and can be seen
from 16 nautical miles away. The most powerful light in Australia
is Cape Byron Lighthouse, with 2,200,000 CD. The French light
at Creach Ile D’Ouessant is the most powerful in the
world, with 500,000,000 CD. **For comparison a car headlamp
on high beam produces 75,000-95,000 CD
• The lens was designed by Jean Augustin Fresnel and
is made up of a series of lenses and prisms which concentrate
a horizontal light out to sea. The Chance Brothers perfected
its manufacture in the shape of a bee-hive.
• In 1913, the famous ‘Brewis Report’ was
published to review the operation of existing lighthouses
on the southeast coast of Australia. As a result, there were
many changes to the operation of lighthouses. At Split Point
the report recognized that the light sectors were inconsistent
with the universally accepted system. Red is the colour universally
adopted to indicate danger, and must be positioned outside
of the white light. It is aligned to headlands, points and/or
reefs. At Split Point red was shown where white should be,
and white where red should be expected to be positioned. Therefore,
shortly after the report, the situation was fixed, where the
white inshore sectors were converted to red by utilising the
red glass shades from the main light. Prior to this change
it was reported that many ships were confused by the signal. |
