什麼是 Lux(勒克斯)
Lux(勒克斯)是用於量化光照強度水平的標準化測量單位。它是照度的單位,代表落在特定表面積上的光通量。簡單來說,lux 是亮度的度量。表面的每平方米內流明(lumen)越多,lux 水平就越高,表示照明越亮。相反,較低的 lux 水平則表示照明較暗。

How Many Lux Is Considered High Light
A light meter measures levels of illumination, in Lux (Lumens per square metre). Low light is considered to be in the range of 270 to 807 Lux, while medium light falls within the range of 807 to 1614 Lux. High light, on the other hand, is classified as being in the range of 1614 to 10764 Lux.
