Light reflectance selector
The Light Reflectance selector identifies USG ceiling panels that
efficiently reflect light within a space to enhance indirect lighting,
reduce energy consumption and create a warm, luminous aesthetic.
Measured per ASTM E14771, LR value represents the percentage of
light reflected from the surface of a material. The industry average for
panels is LR .70 to .80, and values above LR .85 are considered high.
USG offers numerous panels with LR values at these levels, including
SONATA, MARS CLIMAPLUS, OLYMPIA II and OLYMPIA MICRO
PERFORATED, with LR .89.
• Choosing high-LR ceiling panels is a great way to improve the utility and comfort
of the spaces you design and make your projects bright and inviting. Indirect lighting,
combined with high-LR panels, can eliminate dark, shadowy areas and too-bright hot
spots, improving the look and feel of a space and minimizing eyestrain (a cause of
employee fatigue).
High-LR ceilings can also help conserve energy and cut operating costs by achieving
the same light levels with fewer fixtures and lower-wattage bulbs. Fewer fixtures also
mean less repairs and lower maintenance costs.
Architects typically select high-LR ceiling for spaces that make extensive use of
indirect lighting. However, these panels can enhance almost any lighting scheme and
so can be an effective choice for many design applications.
Many USG panels with high LR values also feature high NRC and CAC ratings so you
dont have to compromise acoustics for aesthetics. Panels are available in a range of
textures including smooth and very fine, many include CLIMAPLUS performance, and
several are cast products, which provide a higher level of durability to resisit and hide
scrapes and scratches.

1. Standard Test Method for Luminous Reflectance Factor of Acoustical Materials by Use of
Integrating-Sphere Reflectometers.
Light Reflectance
It is a measure of the percentage of light
which is reflected off of a given panel surface.
Typically, the whiter and smoother the panel,
the higher the LR value.
