LED technology.
Get standard-setting,
functional efficiency without
aesthetic compromise.
Philips Alter LED luminaires combine state-of-the-art, flexible and globally-recognized LED lighting
platforms with proven Alter optical combinations.
Improved efficiency
The result is the optimal performance and ambiance you have come to expect from an Alter specification
with unparalleled energy efficiency—all in a variety of indoor lighting applications, such as office and retail
lighting environments.
Influence behaviour
Lighting is one of the most powerful ways to influence behavior and encourage creativity. Soft light by Alter LED
luminaires deliver effective, efficient lighting for the way people work and interact—for today and tomorrow.
A versatile design specification, created by sculptor/designer Alain Tergny and introduced in 1995 has fostered a range of over 20 luminaire
designs in the Alter family. By delivering the ideal blend of light quality and visual appeal in thousands of offices across Canada, Alter has
become the first choice of specifiers and designers.

Why does
LED make sense?
By choosing Philips Alter LED luminaires for your interior soft light application, you have the
assurance that the excellence in design and aesthetics you expect from Alter is matched by
incomparable light-source quality and efficiency of operation.
Consistent, quality lighting
All Philips global LED platforms utilize high quality
LEDs, rigorous quality control processes and
streamlined manufacturing to ensure high-quality
LED light sources. Coupled with an optimized optical
design, Alter LED luminaires are sure to deliver the
consistent, quality lighting needed to create a pleasing
lighting ambiance. These credentials are particularly
valuable where uniformity and full-colour spectrum
display are important.
Ease of maintenance
The key to optimum performance with LED is
keeping junction temperatures, and all other electrical
components, as cool as possible. Philips Lightolier
conducts rigorous heat testing during the design phase
so that Alter LED components do not exceed maximum
temperature ratings. The use of low-drive current
technology helps keep operating temperatures low to
deliver superior efficacy and longer system life than
luminaires using fluorescent light sources.
Balanced brightness
Philips has been a pioneer of lighting technology and now
continues to lead the way in the research, development,
and application of LED technology. That experience
demonstrates that LED light sources like Alter LED are
effective at delivering comparable levels of illumination to
fluorescent sources but at significantly reduced power
densities (W/sq ft). The energy savings can be significant.
Controlled distribution
Alter LED luminaires provide balanced brightness with
exceptional lighting uniformity for maximum visual comfort.
The products can be easily dimmed to precisely tailor light
levels to particular occupant needs (and save even more energy).
Future-focused
Luminaires that utilize Philips LED platforms allow you
to specify your lighting with confidence. Philips is a global
lighting innovation leader. Our LED-based platforms are
supported and maintained for continuous improvement
as LED technology changes and continues to advance.
An Alter LED specification is the ideal blend of the latest,
proven technology, designed and engineered for interior
soft-light applications.

Alter LED luminaires deliver better uniformity
and reduced power densities.
A new standard in efficient soft lighting without any aesthetic compromise.
Proven advantages
When comparing Alter LED against a
standard fluorescent installation in a typical
office environment, the impact on power
densities and light uniformity is immediate.
Alter LED ensures that your lighting dollar
is maximized while maintaining your
architectural vision. The following two
applications outline how Alter LED can
provide better uniformity and reduced power
densities in your commercial application.
Application 1: This Alter Concept Elegance Lens LED installation,
uses nine (9) fewer luminaires than a comparable fluorescent
installation. It achieves similar light levels with a better uniformity,
while reducing power densities by 43%1.
1 55%
less than ASHRAE 90.1 2010
Application 2: Using 45 luminaires in either installation can
achieve similar light levels with a better uniformity while reducing
power densities by 28% using the same number of luminaires in
both installations2 .
