Décor Series™ Class A
Light is a powerful, natural, medium that can be used to influence well-being and human behavior. LED technology
advancements are using scientific research, along with human reaction, to hone new color points that result in positive
experiences.
What is Class A or Human Centric Lighting?
Created by Behavioral Scientists at the Lighting Research Center (LRC), with Bridgelux and other Alliance for Solid-State Lighting
Illumination Systems and Technologies (ASSIST) members, Class A lighting redefines high quality light. Class A was developed
from worldwide tests on sample groups of consumers and lighting professionals to determine the most preferred white points.
The end product is a unique set of white points with a balance of CRIs for good color rendering and and Gamut Area Indices to
render color saturation.
Class A is defined by its overall appeal, its brightness and how natural it feels to the human eye. Colors are vivid and whites are
at their whitest.
What is Gamut Area Index or GAI?
Bridgelux Décor Series Class A Chip-on-Board (CoB) LED arrays feature a new approach to color targeting that addresses the way
the human eye perceives color.
Gamut Area Index (GAI) is a metric that, when
combined with CRI, more accurately describes the
overall effect of light than just CRI measurement.
CRI only provides a comparative score for color
rendering consitency but does not capture color
saturation. The human eye perceives both
attributes in viewing a color. GAI measures the
saturation or dominance of a color and, combined
with CRI, is a more accurate representation of how
a person will perceive color.
The internationally recognized LRC (make this a
hyperlink to LRC), with whom Bridgelux
collaborates, has carried out years of research on
how the human eye perceives light. Optimized
color points, defined by GAI values, are then
developed based on viewer’s preference. The
human eye perceives light as the combined effect
of hue, saturation and brightness. All of these
factors must be considered to accurately characterize light.
Gamut Area Index plots the relative values of each of the CRI reference colors on the color space. This captures additional
information about how the source renders color saturation. In the example below, Class A is compared to a halogen light
source. The larger area of Class A (on the right) indicates the ability of Class A to render a wider range of color and saturation.

Warm white color point
Energy efficient lighting with long lifetime
Benefits:
Optimized light creates comfortable ambience that feels natural for users of the space
Evokes a positive emotional response
Enhances prestige of premium locations
Makes colors POP; creating a stunning visual experience
Increases visits, use of services, customer purchases and $/sq ft
Does not damage artwork and interior fixtures
Light does not discolor or age produce
Ideal for CDM and CMH replacement
Better light quality matched to human preference
Reduces electricity, AC cooling and operating costs
Applications:
Lighting has become a critical design feature for high-end premium spaces like retailers,
hotel lobbies, museums, and restaurants. Solid state lighting technology is playing an
increasing role in helping operators enhance the environment of such locations to offer a
highly differentiated experience.
Outstanding illumination that optimizes the ambience, architectural features and
merchandise increases number and duration of customer and user visits to the space.
Users and customers are drawn to a well-lit space. Perceptions are enhanced, value of
product rises, and overall moods are improved. The result is an increase of revenue per
square foot.
Selecting the Right Class A Light Source
Bridgelux offers two CCT options (3000K and 4000K) to provide lighting designers with a
range of white points match specific application color rendering needs. The 3000K Class A
LEDs offer vibrant color rendering with clean/bright whites and unmatched natural color
representation. The reds, purples, oranges, greens, yellows, and blues are naturally vibrant
and spectacular when compared to halogen and light resources. The 3000K Class A has an

attractive and familiar color warmth that is highly desired by average consumers. The 4000K Class A offers the brightest/cleanest
white and blue/purple rendering in the industry. The 4000K Class A is a perfect replacement for matching Ceramic Metal Halide
light sources. The 4000K is a favourite with lighting designers who are especially discerning when it comes to illuminating
white/black and colorful objectives. Class A (CCT) configurations do not have intentional (harmful) artificial violet spikes in their
color spectrums. Regardless of your specialty application, Bridgelux Decor Series Class A LEDs have you covered.
