Summary
The location was an out-of-town poor area of Port Elizabeth, a port city in the south of the Republic of South Africa, where there were relatively higher safety concerns
of inhabitants because of low illumination and shadowy
zones at night. To solve this problem, High Mast solution
was adopted using GigaTera MAHA 400-W products.
Before
Project
Existing 1-KW HPS lamps were replaced with MAHA
400-W of GigaTera High Mast to save energy by 60%
as well as improve illumination by amazingly twofold
(measured at 80 m away from a light pole).
Because the area was wide and poles were installed at
a long distance from each other, site inspection and
simulation analyses were conducted several times to
find and apply the optimal solution, desired illumination,
and uniformity factor values.
After
Benefit
As a result, very bright lighting was created for even illumination without any shadowy areas at night to ensure
comfortable and safe living conditions even at night.
An analysis performed after the installation showed
positively reduced crime and accident rates.
GigaTera provides beautiful lighting for a brighter world
and a happier future, and one can enjoy the value of our
lighting in all corners of the world.
“Beyond the Light” provides value beyond simple
lighting.
