The design brief
A pendant luminaire without
louvre to create a
furniture/lighting layout
independent system.
Controlled direct and reflected
glare on VDU screens and on
the task area.
The solution concept
An extremely shallow
suspended luminaire without
louvre with twin ELDACON®
panels. 75% of the light is
projected up and 25% is
projected down by the panels.
The direct/indirect light
distribution, which is defined
accurately will be achieved
with an extremely soft
brightness transition and
balanced shadow conditions
in the room, as well as all
round glare free light.
• These are custom made
products with prices and
availability confirmed upon
request.
