The following selected foot-candle ranges represent the Illuminating Engineer Society’s (IES) current illuminance recommendations. Individual applications will determine exact foot-candle levels. Please refer to the IES Lighting Handbook for more detailed evaluation Industry Application FootCandles Recommended Airplane The way in which the IES and other lighting professionals communicate how much light should be used in a space is to give lux or foot-candle recommendations. Both of these are measurements for how much light makes it onto a surface. Lux means lumens per square meter, and foot-candles means lumens per square foot.

facility lighting should provide recommended minimum illuminance levels, along structures is 54 lux (5.0 foot-candles) and for lots is 10 lux (1.0 foot-candle). Table 4 outlines five lighting zones for parking lots classified by IES RP-20-14. FOOT CANDLE LIGHT Guide The Illuminating Engineering Society (IES) recommends the following footcandle levels to ensure adequate illumination and safety for occupants. Below is a guideline for common areas to assist in achieving appropriate light levels with the greatest energy-e˚ciency .

Airplane Manufacturing A footcandle (fc), the most common unit of measure used for quantifying light levels, is a measure of illuminance with one footcandle being equal to one lumen per square foot. The Illuminating Engineering Society (IES) has established recommended
IES LM-79-08: IES Approved Method for the Electrical predicted illuminance pattern and resulting initial light levels (expressed in footcandles, fc). As shown in
The Photometric Tool provides a rich array of charts and tables summarizing the using the criteria and procedures set forth by the IES for Roadway lighting. Nov 9, 2018 For lighting, these guidelines cover various design aspects, while referencing IES RP-28 for minimum recommended light levels, which are Mar 16, 2017 The Illuminating Engineering Society of North America (IES) has these effects into its lighting recommendations for low light levels, found in the IES would result from illuminance of approximately 3 footcandles (30 lux).
