The standard for recessed lighting – Cooper Lighting’s accordTM is the energy efficient T5 or T8 solution to
better lighting. The accordTM redefines lighting by improving on aesthetics, comfort and energy savings.
The accordTM enhances lighting in both the vertical and horizontal zones, eliminating surface shadows
commonly found in traditional lighting sources. The accordTM produces a "softer" vertical light making it
the ideal lighting solution for schools, hospitals, retail and offices.
Introduction
Improve your lighting

2
Improve visual perception
•The accordTM evenly distributes light, making the space more pleasing to the eye.
•Dark spots (cave effect) associated with parabolics are eliminated.
Attractive design
•Smooth, curved surfaces are attractive but subtle.
•Soft white frosted acrylic lens fills the space with even illumination.
•High reflectance matte white finish blends into the ceiling for a discreet
but efficient fixture.
Enhanced space
•By evenly distributing the light through the space and eliminating the “dark spots”,
accordTM will make a room feel soft, comfortable and inviting.
Save money
•The accordTM is an extremely efficient luminaire that reduces energy consumption
by up to 40% (when compared to a standard 18 cell, 3 lamp, T8 parabolic),
while providing the right amount of “softer” light.

Parabolics are designed to direct light into the cut-off zone,
while restricting light into the shielded or glare zone. In other
words, parabolics deliver light to the work plane and suppress
high-angle brightness.
Due to the high-angle cutoffs as shown in Figure 1., parabolics
can create areas where light is concentrated and areas where
there is no light. These areas of minimum light are referred to
as “dark spots”.
lighting before accord
To eliminate the “dark spots” and sharp cutoffs created by
parabolics, Cooper Lighting designed accordTM. The accordTM
provides a feeling of spaciousness and does not substantially
increase glare, as shown in Figure 2.
The accordTM provides the following advantages:
• Improved visual perception
• Enhanced space
• Attractive contemporary design
• Significant energy savings

Significant energy savings
The accordTM not only improves lighting, but benefits the
environment as well, by providing up to 40% energy
savings compared to a standard 18 cell, 3 lamp parabolic.
The accordTM also assists in meeting energy regulations
such as California’s Title 24 and ASHRAE 90.1.
Improved visual perception
By reducing the “dark spots” and evenly distributing
light, accordTM makes it softer on the eyes.

By evenly distributing the light through the space and
eliminating the “dark spots”, accordTM will make a room
feel soft, comfortable and inviting.

accordTM maximizes savings
Choose either T5 or T8 technology to best meet your lighting needs. With a multitude of lamp and ballast combinations, the
accordTM can deliver the perfect amount of light with a maximum energy savings. New high-efficiency ballast drive T8 lamps with
less energy than standard T8 ballast yet producing equal or more lumens. Compared to standard 3 lamp, 18 cell parabolics,
the accordTM utilizing high lumen lamps and high efficiency ballasts saves up to 40% on energy costs.

Appearance and performance make accordTM the lighting choice.
Energy savings makes accordTM a sound financial decision.
The accordTM family of products saves up to 40% energy costs
when compared to a standard 3 lamp,18 cell parabolic. The dimming
feature reduces energy consumption by another 50%.
The accordTM meets and exceeds ASHRAE 90.1 2001 standards
by approximately 40%. This provides office space a tax benefit of
approximately $0.60/sq. ft.
Save energy costs
The accordTM is an ideal substitute for 3 lamp T8 systems, 4 lamp
T8 systems and inefficient 4 lamp T12 systems. The accordTM is
the solution in new construction or remodel applications. The
accordTM evenly distributes light making the space more pleasing
to the eye, provides light levels that are in accordance with IES
recommendations, and reduces energy costs. The accord’sTM step
dimming option reduces energy consumption by an additional
50% when activated. The following example illustrates
