About These Units
Lumen per Square Foot (lm/ft²)
Lumens per square foot (lm/ft²) is identical to foot-candles. The defining relationship: one foot-candle = one lumen per square foot. Used in US lighting calculations: lumens needed = foot-candles × square feet. Standard in American architectural lighting design.
Kilophot (kph)
A kilophot (kph) equals 1,000 phots or 10,000,000 lux (10 megalux). Represents extreme illumination far beyond natural conditions. Theoretical unit for laser and concentrated light applications. Direct sunlight maximum is only about 0.01 kilophots.
