The facts on the card
The card carries these facts from its Wikipedia article.
- It is a measure of how much the incident light illuminates the surface, wavelength-weighted by the luminosity function to correlate with human brightness perception.
- Similarly, luminous emittance is the luminous flux per unit area emitted from a surface.
- Luminous emittance is also known as luminous exitance.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Illuminance article was read about 24,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 53 and blocks with 42: each hit it takes is cut by 17 %.
