When it comes to lighting up your business, do you just add random lights everywhere or do you try to plan where to place your fixtures to gain the most light? Well, this is where footcandles come in handy. Footcandles are defined as the illuminance on a one square foot surface from a uniform source of light. Footcandles are the most common unit of measure that is used by lighting professionals to calculate the light levels in businesses and outdoor spaces. There is a Society called the Illuminating Engineering Society (IES) who recommend following the footcandle light guide to ensure adequate illumination and most importantly, safety!
The amount of light that is falling on a surface is called, "illuminance". This unit is measured in lux (metric unit=lumen/m2) or footcandles (English unit = Lumen/ft2). 1 footcandle equal 10.8 lux and with this measurement you'll work most with for optimizing visual comfort. This is because building regulations and standards will use illuminance to specify the minimum light levels for specific environments and jobs.
