=== Security lighting ===
{{See also|Natural surveillance}}
[[Security lighting]] is another effective form of deterrence. Intruders are less likely to enter well-lit areas for fear of being seen. Doors, gates, and other entrances, in particular, should be well lit to allow close observation of people entering and exiting. When lighting the grounds of a facility, widely distributed low-intensity lighting is generally superior to small patches of high-intensity lighting, because the latter can have a tendency to create blind spots for security personnel and CCTV cameras. It is important to place lighting in a manner that makes it difficult to tamper with (e.g. suspending lights from tall poles), and to ensure that there is a backup power supply so that security lights will not go out if the electricity is cut off.<ref>{{cite book|author=Kovacich, Gerald L.|author2=Halibozek, Edward P.|name-list-style=amp|title=The Manager's Handbook for Corporate Security: Establishing and Managing a Successful Assets Protection Program|publisher=Butterworth-Heinemann|year=2003|isbn=9780750674874|pages=192–193|url=https://books.google.com/books?id=WZ9_hnqNpH0C&pg=PA193|url-status=live|archive-url=https://web.archive.org/web/20180105015948/https://books.google.com/books?id=WZ9_hnqNpH0C&pg=PA193|archive-date=2018-01-05}}</ref> The introduction of low-voltage LED-based lighting products has enabled new security capabilities, such as instant-on or strobing, while substantially reducing electrical consumption.<ref>{{Cite web|title=Use of LED Lighting for Security Purposes|url=http://silvaconsultants.com/use-of-led-lighting-for-security-purposes.html#:~:text=More%20directional:%20LED%20lights%20can,and%20in%20other%20security%20applications.|access-date=2020-10-06|website=silvaconsultants.com}}</ref>

==== Security lighting for nuclear power plants in the United States ====
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. Per [https://www.ecfr.gov/current/title-10/part-73#p-73.46(b)(7) 10 CFR 73.46(b)(7)] "-Tactical Response Team members, armed response personnel, and guards shall qualify and requalify, at least every 12 months, for day and '''night''' '''firing''' with assigned weapons in accordance with Appendix H-"; therefore on said respective [[shooting range]] '''[at night]''' per [https://www.ecfr.gov/current/title-10/chapter-I/part-73/appendix-Appendix%20H%20to%20Part%2073 Appendix H, Table H-2], "-all courses [shall have] 0.2 '''<u>[[Foot-candle|foot-candles]]</u>''' at center mass of target area-" applicable to [[Handgun|handguns]], [[Shotgun|shotguns]], and [[Rifle|rifles.]] [https://www.ecfr.gov/current/title-10/chapter-I/part-73/appendix-Appendix%20H%20to%20Part%2073 <sup><nowiki>[Ref]</nowiki></sup>] 1 [[foot-candle]] is approximately 10.76 [[lux]], therefore the minimum illumination requirements for the above sections also reflect '''<u>2.152 [[lux]]</u>'''.
