Now let’s look deeper at how we measure illuminance – We start by looking at the two fundamental lighting units of measure: lumens and illuminance (footcandles/lux). Measuring the amount of light that falls on a surface allows us to evaluate if we have sufficient light to perform various visual tasks. Therefore, light intensity is measured in terms of lumens per square foot (footcandles) or lumens per square meter (lux). It is measured in footcandles or lux – it is the amount of light (lumens) falling on a surface (over any given square foot or square meter). Illuminance is the metric that is used to measure the light intensity within a space. What is the Best Metric to Measure Light Intensity?
LUMEN SCALE DISTANCE HOW TO
This article will cover a few basic principles related to light intensity – how to measure light intensity, the difference is between lumens and illuminance (and what they mean), plus we will discuss the ways in which artificial light has become so critical to our daily lives and well-being.
Shop for Architectural Lighting Solutions by BIOS It is especially useful to understand light intensity in order to properly evaluate whether or not a space has adequate lighting conditions. The lighting industry has well-established light level recommendations for a wide range of applications and space types. In architectural lighting, light intensity or light output is measured to understand whether a particular light source provides enough light for an intended application.
