INCREASING CONCRETE SURFACE
LRV

Light Reflective Value is a universal scale that measures the amount of visible and
usable light reflected from a surface when illuminated by a light source. It is used
in architecture and interior design to determine how much light a color reflects or
absorbs. LRV is measured on a scale of 0% being completely absorbing black that
reflects no light, to 100% being completely reflecting white that reflects all light.
Because the reflectance value is a proportion of the light reflected off the surface,
rather than the amount of light that falls on it, typically the brightest whites have an
LRV of 85% points, and the darkest blacks have an LRV of 5% points.

Increasing concrete surface LRV (light reflective value) will reduce the amount of
light needed to achieve the desired illumination per the task at hand.
