Light Reflectance Value (LRV) is a universal value for ‘contrast’ which measures the total quantity of visible light reflected by a surface at all wavelengths and directions when illuminated by a light source.

Nov 14, 2023 · The standards recommend an LRV contrast of at least 30 points, with 20 points being acceptable if the illuminance on the surface is 200 lux or more. If door opening furniture projects beyond the face of the door or creates an enhanced differentiation in shade, the LRV contrast must be a minimum of 15 points.

LRV (Light Reflectance Value), is a measure of how much visible and usable light is reflected by all directions and wavelengths from a surface when illuminated by a light source. Different colours reflect different amounts of light, and this is measured on a scale of 0 – 100%.

Light Reflective Value (LRV) is a measurement (0 to 100) which expresses the percentage of light that is reflected from a surface. Black is 0, with pure white being 100.

Light Reflectance Values, or LRV, is a way to measure how much light is reflected from a surface when it is hit by light. Architects and designers use it to see how much light a colour reflects or absorbs.

n LRV rating for Coachman® Doors: Light Reflective Value (LRV) measures the amount of light reflected from a painted surface. LRV is important to determine if the color is permitted on our Coachman® garage doors and this document shows if the color is approved. n Note: Specific LRV and Solar Reflective requirements ONLY apply to Coachman ...

When specifying doors, it is important to consider the LRV contrast between the door facing and ironmongery, in order to comply with BS 8300:2018 requirements. The figures below give an indication of the Light Reflectance Values of commonly used veneer & …

BS 8493:2008+A1:2010 – 'Light reflectance value (LRV) of a surface – Method of test', uses the CIE Y, x, y values measured under standard conditions, with a sphere-type spectrophotometer. This method will give an accurate value for the LRV of a …

Light Reflectance Value (LRV) measures the percentage of light a color reflects. It's important in design for accessibility, as it helps determine the contrast between different surfaces, aiding visibility for people with visual impairments.

To show the light reflectance values (lrv) and visual contrasts derived select the door facing, lipping, intumescent and/or ironmongery species/finish from the drop-down lists below.
