HIGH DIFFUSE REFLECTANCE
FOR HIGH EFFICIENCY LIGHT FIXTURE DESIGN
WhiteOptics™ Metal
WhiteOptics™ develops and manufactures the patent-pending
Coil metal composite
Can be roll formed, progressive die
stamped, punched
Available in cold rolled steel and Aluminum
WhiteOptics™ Reflector based on a highly reflective plastic substrate.
White97™ Film
Insertable reflector, 18 mils thick
Available in rolls, custom width
Die-cut and thermoformable
Available with adhesive backing
and release liner
The reflector is unique in that it has extremely
high diffuse reflectance and has greater than 97%
reflectance across the visible spectrum, allowing
light fixtures to be designed with more efficient
light output while the highly diffuse nature of
reflection allows light to be distributed evenly with
a low-glare æsthetic.

Energy Efficiency
Why does 5 to 20% fixture efficiency improvement matter?
Fixture
Manufacturers
Fixture efficiency is becoming a strong point of differentiation. Increases of even 2% are significant.
High reflectance coil eliminates need for post-forming powder coat paint.
Lighting Specifiers
Willingness to pay premium for increased efficiency and white, diffuse distribution
Building Owners
2-year payback in energy savings is a “no brainer” for investment

Why does 97% reflectance matter?
Every time a light ray is reflected, a portion will be absorbed by the reflecting surface. Many current fixture
designs involve multiple reflections to achieve good aesthetics for indirect lighting or tight cavities. Used in
such situations, a high performance reflector will minimize absorbance from multiple bounces and maximize
the usable exiting light. A small difference in reflectance can make big difference in lighting efficiency.
Why does high diffuse reflection matter?
For typical indoor lighting applications, many designers would like to present a uniform, soft lighting
experience, avoiding unpleasant glare and uneven “hot spots.” This becomes even more critical with LED
light fixtures where diffuse reflectance is needed to hide multiple lamp images and mix color.
