T5 Luminaire
I
nnovative in form and function, Columbia’s revolutionary Brio maximizes the
advantages of T5 lamp technology, combined with the beauty of perf and the
precision optics of parabolic louvers. The result is a stunning blend of performance
and style in an astonishingly low profile housing.
Beauty, performance, value
Integrating the beauty of perf, the precision optics of parabolic louvers, and the innovation of T5
technology, Columbia Lighting introduces Brio – a truly revolutionary advance in appearance
and performance.
Distinctly different, yet more than merely attractive, Brio meets the standards of IESNA RP-1
for computerized environments by delivering light to the task and away from glare-producing
high angles. Add to this the benefit of efficient T5 lumen packages in an amazingly low profile and
you have the most exciting new direct luminaire of the 21st century: Brio – the first of its kind.
Tight Plenums? No Problem!
With its innovative shallow cross section, Brio
redefines the way we think about lighting
fixtures in the plenum. At a depth of 21⁄2″ (31⁄2″
on the “Stretto” narrow version), the luminaire
extends only 1″ above the T-Bar itself, as

with traditional low-glare parabolics (right).
compared to 3-4″ with more typical recessed
fixtures. The benefit? No more competing with
other trades for space above the ceiling. Remodels won’t always require surface mounted
fixtures. In new construction, Brio may even allow for shallower plenums—and lower
construction costs!
Comfortable,
low-glare illumination
Brio achieves what many thought
impossible: A direct T5 fixture with
effective glare control. Even with
three T5 HO lamps, Brio’s precision
optics meet IESNA’s RP-1 recommendations for computerized offices.
The secret lies in the concept of the
“dedicated louver,” coupled with the
slender profile of the T5 lamp. Each
lamp has its own high-performance
optical envelope that controls light

A lumen package for every need
With its near-perfect batwing distribution and versatile set of lamp options, Brio’s wide
choice of lumen packages will provide exactly the right light levels for your job. Plus, we’ve
achieved this level of performance with standard 8′x 8′ or 8′x10′ fixture spacings, making
installation a breeze.

Say Good-bye to “Cave Effect”
The strength of a low-glare luminaire can also be its weakness. The optical design demands a
distribution downward and away from the “glare zone,” the angles above 55 to 65 degrees. One
consequence of this inherent characteristic is dark walls. Rooms can become dreary and cavelike. Well-lit walls are essential to comfortable working spaces, not only for the psychological
perception of a pleasant space, but to avoid the eyestrain associated with excessive contrast.
Columbia designed Brio with wall-washing
capabilities, using the same revolutionary
optical concept as on our groundbreaking
VHC series. Luminaires positioned along
the perimeter of a space can be ordered
with the “single wall-wash” option to
intentionally cast high-angle light against
the wall.
Before - symmetrical distribution.
After - asymmetrical distribution.
In addition, corridors and hallways can be
effectively lit with the “double wall-wash”
option. When ordered with this option,
the 4″ wide Brio “Stretto” is especially
suited to corridor applications.

Integral Cross Tee
The Brio “Stretto” integrates Brio’s remarkable optics into a sleek linear fixture that installs into
standard grid ceilings with ease. Its innovative design works with the ceiling system by actually
serving as a self-contained cross tee.

Step 3
Rest the Stretto’s ends on the tee
and center it in the opening.
Cut the ceiling tile into two
10″ strips.
Drop the ceiling tile into place.
That’s all.You’re done!
