to determine the best and most practical solution.
Following experiments with mock-ups both at
Helmick’s studio in Boston, Massachusetts, and
during extensive lighting trials in Abu Dhabi, dpa
chose multiple light sources with flexible optics and
lighting controls as the optimum approach.
A specially made fixture was developed to the
required optical performance and with sufficient
control over light output to allow for both flexibility
and fine tuning. This had to be proven at full scale,
while fulfilling the additional criteria of budget, load
allowance, accessibility for maintenance, and the
particularly challenging aspect of planning the build
to get hundreds of fixtures integrated within the fine
tolerances of the structure and among the congested
artwork support cables.
In all, 753 downlights and 1203 uplights were custom
made to light the sculpture from above and below in
order to achieve a three-dimensional rendition of the
sculpture at night. Each fixture is fitted with a 3.5W
warm white LED and integral DMX control, which
enables the exact tailoring of the lighting scheme to
respond to the differing textures and forms of the
platonic solids, both individually and collectively.
The scheme called for around
2000 individually directed lights
