metal construction and antennas at the top of the tower with the fixtures. The highoutput, outdoor-rated, LED flood fixtures make the tower the city's focal point with 7,769
total lumens. The adjustable yoke, on-board digital display, and weather-resistant capabilities complete the customized lighting solution.
Permanently illuminated since December 2017, the end result is an energy-efficient,
weather-resistant lighting system that accomplishes Alticom's primary goal: to make a
telecommunication tower a highly visible and recognizable landmark of the City of Alphen aan den Rijn.
"The tower literally serves as a landmark. If you see the tower, you will see Alphen,"
said Woudsma. "With the lighting of the tower we make Alphen aan den Rijn visible, literally and figuratively." CA

In addition to the lights at the base of the tower, the six different floors with balconies on the structure received
their own unique lighting applications. Twenty-four Dyna Flood XT DMX RGBA fixtures with a beam angle of 70
deg. were installed to highlight the six floors.

"World cities such as Paris, London, and New York already have iconic buildings that
can be illuminated for special occasions," said Gert-Jan Woudsma, owner of Hillsafety.
"Alphen aan den Rijn will soon be in that list with this illuminated showpiece."
To make the structure comparable to the Eiffel Tower or the Empire State Building, the
tower is illuminated daily with a basic color scheme of white and green, in reference to
Alphen aan den Rijn as the center of the "Green Heart," an area in the Dutch "Randstad,"
which is a megalopolis in the central-western Netherlands. The colors can also be adjusted
for special events and celebrations. For instance, the tower is covered in green and red light
during Christmas time, orange on the King's Day, and red, white, and blue in celebration
of Liberation Day.
As a permanently illuminated building, the products used to light the tower needed to
be weather resistant, long lasting, and bright. Working in tandem with ETK Lighting to
create a custom lighting system, Acclaim Lighting representatives selected fixtures with a
high IP66 rating for wet locations to provide resistance against strong winds and extreme
weather conditions.
To illuminate the concrete base from the bottom upward, four Acclaim Dyna Drums
HO 4000 K with a beam angle of 6 deg. were installed, each providing 10,103 total lumens. The fixtures feature an adjustable yoke for customizable focus and an onboard
digital display for menu selection and adjusting color schemes. With a lumen maintenance rate of 50,000 hr. at 70%, the fixture will remain bright for years-an important
quality requirement for fixtures used on a permanently illuminated structure.
In addition to the lights at the base of the tower, the six different floors with balconies
on the structure received their own unique lighting applications. Twenty-four Dyna Flood
XT DMX RGBA fixtures with a beam angle of 70 deg. were installed to highlight the
floors. Because of their high output and weather resistance, the fixtures provide a solution
for large-scale facade lighting and flood illumination, featuring a total lumen output of
3,200 for the RGBA version. With an adjustable head and internal DMX driver, the
brightness and placement of the concentration of light can be adapted to the desired use.
Finally, two Dyna Drums SO 4000 K were incorporated into the design, crowning the
