==Measures of Luminescence==
The elements of Light and Dark have a simple relationship â€“ the more Light, the less Dark, and ''vice versa''. There are several ways of measuring the Luminescence provided by this interaction. One measure is the so-called â€˜percentage of Lightâ€™, which is commonly used by [[Celestial]] Adepts. Another, more mundane, measure is the foot-candle. One foot-candle is the amount of light shed by a normal candle at the distance of one foot. These two methods have a natural logarithmic relationship where 10% more light is 10 times as many foot-candles -- except at extreme light levels, where the â€˜percentage of Lightâ€™ measure is distorted by the limits of Elven vision. The following table describes the light level in many common situations.

==Light Table==
This table differs slightly from the table in the [[Celestial#19.10_Celestial_Lighting_Modifier_Table|Celestial]] College. That table is the correct and approved 'rule' for Lighting Modifiers.

==Changing Light Levels==
As magical Light or Darkness spells change the Light level by 2%/Rank: each additional rank of Light increases the luminescence (in foot-candles) by 60%, as if the light source were 25% closer; 3 ranks makes it 4 times brighter, or as if the light source was twice as close; and 5 ranks makes it 10 times brighter, or as if the light source was 3 times closer. This relationship fails for Light (or Dark) levels above about 90%.
