The footcandle (or lumen per square foot) is a non-SI unit of illuminance. Like the BTU, it is obsolete but it is still in fairly common use in the United States, particularly in construction-related engineering and in building codes. Because lux and footcandles are different units of the same quantity, it is perfectly valid to convert footcandles to lux and vice versa.<br \/>\nThe name &#8220;footcandle&#8221; conveys &#8220;the illuminance cast on a surface by a one-candela source one foot away.&#8221; As natural as this sounds, this style of name is now frowned upon, because the dimensional formula for the unit is not foot \u2022 candela, but lumens per square foot.<br \/>\nSome sources do however note that the &#8220;lux&#8221; can be thought of as a &#8220;metre-candle&#8221; (i.e. the illuminance cast on a surface by a one-candela source one meter away). A source that is farther away casts less illumination than one that is close, so one lux is less illuminance than one footcandle. Since illuminance follows the inverse-square law, and since one foot = 0.3048 m, one lux = 0.30482 footcandle \u2248 1\/10.764 footcandle.<br \/>\nTIPS FROM CLEMENT: Illuminance (light level) \u2013 The amount of light, measured in foot-candles (US unit), that falls n a surface, either horizontal or vertical.<br \/>\nParking lots lighting needs to be an average of 2 foot candles; uniformity of not more than 3:1, no area less than 1 fc.<br \/>\nAll illuminance measurements are to be made on the horizontal plane with a certified light meter calibrated to NIST standards using traceable light sources.<br \/>\nThe CISSP Exam Cram 2 from Michael Gregg says: Lighting is a commonly used form of perimeter protection.<br \/>\nSome studies have found that up to 80% of criminal acts at businesses and shopping centers happen in adjacent parking lots. Therefore, it&#8217;s easy to see why lighting can be such an important concern.<br \/>\nOutside lighting discourages prowlers and thieves. The National Institute of Standards and Technologies (NIST) states that, for effective perimeter control, buildings should be illuminated 8 feet high, with 2-foot candle power.<br \/>\nReference used for this question:<br \/>\nHARRIS, Shon, All-In-One CISSP Certification Exam Guide, McGraw-Hill\/Osborne, 2001, Page 325. and Shon&#8217;s AIO v5 pg 459 and <a href=\"http:\/\/en.wikipedia.org\/wiki\/Foot-candle\" title=\"External link\" rel=\"nofollow noopener\" target=\"_blank\">http:\/\/en.wikipedia.org\/wiki\/Foot-candle<\/a><\/div>\n<p><\/strong><\/span> <\/div>\n","protected":false},"excerpt":{"rendered":"<p>The National Institute of Standards and Technology (NIST) standard pertaining to perimeter protection states that critical areas should be illuminated up to?
