What is LRV for timber?
LRV is a universal value for ‘contrast’. It measures the proportion of useful light reflected by a coloured object. It represents a relative light and darkness value rather than an actual colour. Therefore, dissimilar colours could have the same LRV.
How is light reflectance value calculated?
This contrast is calculated using the following formula: (B1 – B2) x 100 / B1, where B1 and B2 are the LRV of the lighter area and darker area, respectively. The LRV can be obtained using the CIE Y values measured under the illuminant D65 (natural daylight) and 10° observer.
What does LRV mean in flooring?
Light Reflectance Values
In architecture, Light Reflectance Values (LRV), are a measure of the percentage of visible and usable light that is reflected from a surface when illuminated by a light source.
Does wood absorb light?
When something is clear, like glass, visible light passes straight through it without being absorbed or reflected. Wood, on the other hand, absorbs the light in wavelengths we can see.
Does carpet have a LRV?
Carpets in plain or multi-colours, pattern variety and pile textures very rarely reach either end of the LRV spectrum and while high LRVs are in many instances the primary aim in the flooring industry and with interior design consultants as this means a lesser level of artificial light is required.
Is SRI the same as LRV?
LRV and SRV and SRI are NOT the same property and cannot be used interchangeably! While there is some overlap between LRV and SRV, and many coated surfaces may have similar LRV and SRV values, they are not the same measurement.
What is the LRV of stainless steel?
Stainless steel finishes depend upon the level of polishing applied but as a rule of thumb, satin stainless steel has an LRV of 39 and high polished stainless steel has an LRV of 45.
What is a good LRV for exterior?
A good white exterior paint should have an LRV between 73-ish to 85. You can find the LRV of a paint color on the manufacturers website.
How do I find LRV in paint?
Where to find a paint color’s LRV when choosing a color? Paint manufactures create paint chip cards to help customers view each color. The LRV # can be found on the back of the paint chip card or online.
What is a good LRV for a dark room?
For general painting, decorators suggest using a paint that has an LRV of 50% or higher, which means the color reflects more light than it will absorb. If you have a darker room, however, you’ll want to find colors that have an LRV of 60% or more.
What material absorbs the most light?
Vantablack
Vantablack (Vertically Aligned Nanotube Array BLACK) can absorb 99.965 percent of ultraviolet (UV), visible and infrared (IR) light. British researchers at Surrey NanoSystems helped developed the material, and its properties can be used on telescopes as well as making objects seemingly disappear.
What material absorbs all light?
The best they made was Vantablack. This material is made of vertically aligned carbon nanotubes ( hence the name). It can absorb 99.965% of light.
What is LRV rating for carpet?
LRV measures how much of the ambient light a surface reflects back. The value is expressed as a percentage, 0 being a perfectly absorbent surface and 100 being a perfectly reflective surface; it’s the difference, for instance, between black velvet and a white fridge.
What is LRV rating for carpet tiles?
The LRV scale runs from 0 to 100 and when it comes to light reflection, it is a case of the more the merrier. So all you really need to remember is that the higher the LRV, the more light the carpet tile will reflect and the less artificial light you’ll need.
What paint has the highest LRV?
Simply White has a LRV of 91.7, which is nearly the highest of all the paint colors on this list. The high LRV means it is the closest to pure white.
What is the LRV of pale oak?
70
While the colors are very similar, Pale Oak is a little bit lighter than Edgecomb Gray. Pale Oak has an LRV of 70 and Edgecomb Gray has an LRV of 63, meaning it reflects a touch less light.

Is higher LRV better?
1) The higher the LRV number- the lighter the color is. The lower the LRV number – the darker the color. This can greatly affect your room depending on how much natural or artificial light your room gets. 2) Any color will look lighter when hit with DIRECT natural or artificial light.
Is higher or lower LRV better?
Monet Magic has an LRV of 66, so it reflects much of the room’s natural and artificial light. Colors with an LRV above 50 are lighter and bounce back more light than they absorb. Higher LRVs help create an illuminated, “daytime” feel.
