Attention to Detail

The careful detailing of the regressed steel die-formed end
cap creates strength and a lighter appearance.

Performance

PerfLyte’s Optical Systems offer superior performance. The
light distribution ratios range from approximately 100%/0%
to 60%/40%.

Lighting Application

PerfLyte can be used in a range of commercial and institu­tional applications: open and individual offices, conference
rooms, reception areas, libraries, health care facilities, and
classrooms.

Contractor Friendly

Our simplified mounting system allows you to position feed
and support locations on or off the ceiling grid in a fraction
of the time, minimizing labor costs. See page 6 for details.

Affordable

PerfLyte is affordably priced to fit limited budget projects.

Joining Capabilities

PerfLyte’s modular sections are easily joined end-to-end to
create continuous runs.

Lightolier’s
PerfLyte luminaire
features a streamlined elliptical profile
with an elegant perforated housing in two sizes and four
distinctive diffuser styles. PerfLyte offers high quality lighting in
an array of lighting distributions. Its visual comfort combined with
the benefits of careful detailing, easy installation, product range and
affordability make a great choice for refined commercial applications.
PerfLyte’s simple modular approach enables you to create
uninterrupted continuous runs of any length.
