Re: Aquatic Plants Digest V3 #497
Hello Steve,
*Lux* measures illumination. 1 Lux = 1 Lumen per square meter
.
*Foot-candle* also measures illumination. 1 Foot candle = 1 Lumen per
square foot = 10.764 Lumen / sq. meter = 10.764 Lux.
*Lumen* measures flux of luminous energy. 1 Lumen = 0.07958 spherical
candle power.
Hope this helps.
Best,
George S
