  • Ackchually you need to remake that meme in illuminance (Lux) and not luminous flux (Lumen). As illuminance is luminous flux per unit area, it is a significantly more accurate representation of the output of a lamp because it considers how focused that light source is. Luminous flux only tells you how much total light output a lamp has, which is meaningless if you have no information of how it is directed.
