AL vs. NL: Know the Difference
By Shumaila Saeed || Updated on February 20, 2024
AL (Artificial Light) refers to man-made light sources, whereas NL (Natural Light) refers to light from natural sources like the sun and stars.
Key Differences
AL, or Artificial Light, is created through various technologies such as bulbs and LEDs. NL, or Natural Light, is derived from the sun and other celestial bodies. While artificial light is controllable and can be used anytime, natural light varies based on time and weather.
