LED Downlighting
The System of Choice
Defining the Shape of LED Downlighting
The DōM design shields the high-brightness LED light sources,
offices, reception areas, schools and retail environments. The DōM is
preventing direct view of the source from any angle, and provides

The DōM design combined with highly reflective material creates
a diffused light source that delivers a volumetric light distribution

excellent for commercial applications where glare control is at a
premium (reading areas, waiting rooms, hallways, healthcare).
