What is Scotopic Lumens
Scotopic lumens, in the context of the lighting industry, refer to the measurement of light output that takes into account the sensitivity of the human eye to both cone and rod photoreceptors. Unlike photopic lumens, which measure the sensitivity of our eyes under intense lighting conditions, scotopic lumens are associated with our ability to see in low light or weak light situations. The rods in our eyes are responsible for detecting this type of light and regulating the size of the pupil, which directly affects visual acuity for tasks.
It is important to note that scotopic lumens cannot be measured using a standard light meter. Standard light meters only measure the sensitivity of the eye to cone-activated vision in the fovea (photopic) region of the retina, completely ignoring the impact of vision with rod activation (scotopic). However, recent research has shown that rod photoreceptors are active in weak light and typical interior light levels.

The combination of photopic and scotopic luminosity provides a more accurate representation of how the human eye perceives light at average interior light levels. Therefore, lighting manufacturers and designers have started to consider the scotopic-to-photopic ratio (S/P ratio) when designing lighting solutions. A higher S/P ratio, achieved by using light sources with higher color temperatures, can result in sharper vision, improved color rendering, reduced visual fatigue, decreased disability glare, and enhanced performance for tasks.

Pertanyaan yang Sering Diajukan
What Is Photopic Lighting
Photopic lighting, also known as cone vision, pertains to the adaptation levels of 3 candelas per square meter (cd/m^2) and above. It refers to the overall brightness of the environment that your eyes have adjusted to.
What Is the Difference Between Scotopic and Photopic Lighting
Scotopic lighting relies solely on rods for vision, resulting in the perception of objects in black and white. On the other hand, photopic lighting utilizes cones and enables the perception of color.
Is Moonlight Photopic or Scotopic
Once the sun is below the horizon, the transition from photopic to mesopic and eventually to scotopic vision begins during twilight. It is important to note that scotopic vision is only fully achieved when there is no significant light source present. However, it should be noted that even moonlight, despite being relatively bright, can hinder complete scotopic operation.
What Is Another Name for Scotopic Vision
Also known as twilight vision, scotopic vision can be compared to photopic vision.
