For [[Nuclear power in the United States|nuclear power plants in the United States (U.S.)]], per the [[Nuclear Regulatory Commission|U.S. Nuclear Regulatory Commission (NRC)]], [[Nuclear safety and security#Title 10 CFR Part 73 (U.S. NRC)|10 CFR Part 73]], ''[security] lighting'' is mentioned four times. The most notable mentioning contained in [https://www.ecfr.gov/current/title-10/part-73#p-73.55(i)(6) 10 CFR 73.55(i)(6) Illumination], which clearly identifies that licensees "-shall provide a '''<u>minimum [[Illumination (lighting)|illumination]] level of 0.2 [[Foot-candle|foot-candles]],</u>''' measured horizontally at ground level, in the isolation zones and appropriate exterior areas within the protected area-". [https://www.ecfr.gov/current/title-10/chapter-I/part-73#p-73.55(i)(6) <sup><nowiki>[Ref]</nowiki></sup>] This is also the minimum illumination level specified in [https://www.ecfr.gov/current/title-10/chapter-I/part-73/appendix-Appendix%20H%20to%20Part%2073 Table H–2 Minimum Night Firing Criteria of 10 CFR 73 Appendix H], for night firing.
