Sottile 2D
[sō-tee-lay]
Introducing Sottile [sō-tee-lay] 2D, a new fully luminous
architectural recessed luminaire by Nulite. This cost
effective, energy efficient luminaire series provides
soft ambient illumination with a modern appearance.
Modern

The crisp transitions between our three lenses creates a
clean aesthetic and modern appearance. Our optical system
consists of proprietary lenses which are engineered for balance between light transmission and shielding of the lamp
source along with housing geometry to achieve a cohesive
soft luminous quality.
Nulite offers a multitude of center diffuser options tailored to
modern design. Our standard center diffuser is an extruded
smooth frosted acrylic lens. Optional center lenses are the clear
linear prism, clear linear prism with white radial baffle, frosted
linear prism and clear smooth with perforated overlay.

A larger luminous aperture is achieved when designing without a door
frame. There’s a 9% increase in aperture area with Sottile 2D compared
to a door frame luminaire.
Die formed cold rolled steel housing. Optional, specification grade, 20 gauge cold rolled steel housing painted
after fabrication. Curved back housing allows for easier
installation in reduced plenum applications. Luminaire
can be installed in a minimum plenum depth of 6.5
inches above the grid.
Integral corner pry out grid hooks to
secure luminaire over ceiling grid.
Convenient four corner tie-back locations to secure luminaire to structure
by others. Seismic clips are available
as an option.
The extruded smooth frosted acrylic side diffusers provide
a soft comfortable luminous aesthetic. Lenses can shift for
cleaning and maintenance.
Shift-n-remove center lens for quick maintenance. Standard lens is
smooth frosted acrylic. Optional lenses are clear linear prism, clear linear
prism with white radial baffle, frosted linear prism or clear smooth with
round perf overlay.
Beveled ends secure the lenses,
add dimension and accent the
curvature of the profile.
Lamp and ballast access via spring tension shift-n-remove center lens
Gently grasp the center lens by the
sides and shift to one end.
Pull the exposed end down.
Remove the lens once the lip clears
the housing. Optional lens retainer clip
to support lens during maintenance.
