Using Light Reflectance Values of Paint Colours

Using light reflectance values Reflectance is the proportion of light that a surface reflects compared to the amount of light that falls on that surface. Dark, matt and/or textured surfaces absorb a lot of light and have low light reflectance values.

Reflectance and Transmittance Spectroscopy - Ocean

When properly measured, spectral reflectance can yield much of the same information as the eye, It can also offer information about the material from which a sample is made, since light that is not reflected from a sample is absorbed due to its chemical

Dow Thermax vs. Reflective Insulation and Radiant

Hence, the high reflectance of shiny aluminum provides an excellent resistance to radiation transfer. For a reflective material to be used as an insulator, the reflective surface must be adjacent to an air space, preferably another highly parallel surface. This air

References 1 Reflectance can be calculated by measuring the incident illumination in foot-candles 1 foot-candle = 1 lumen per square foot on a surface and then, under the same lighting conditions, measuring the luminance in foot-lamberts 1 foot-lambert = about 3


PDF In addition, the light reflectance value of a material is also used to calculate lighting requirements for a room. High LRV material on ceilings, floors and walls help reduce lighting requirements by reflecting existing light, either from light fixtures or daylight.

Lighting Research Center Education Learning

IESNA Definition: the ratio of the reflected flux to the incident flux. Reflectance values express the percentage of light that is reflected back from a surface, the difference having been absorbed or transmitted by the surface. Reflectances of room surfaces are used in
