Which statement about night exterior lighting is true?

• A. Low key lighting is required in all night exteriors
• B. Low key lighting is rarely used
• C. Low key lighting is quite common, but not mandatory
• D. Low key lighting is never used indoors

Answer: (C)

Low-key lighting uses strong contrasts and selective illumination to create mood and define space, rather than bathing everything in even brightness. For night exteriors, this approach is quite common because it highlights architectural details, pathways, and landscape textures while keeping glare and skyglow down, which helps with safety and energy efficiency. It’s not mandatory, though—some sites need brighter, more uniform light for safety, security, or wayfinding, so designers may choose higher light levels in certain areas. The other statements miss how lighting is actually used in practice: it isn’t required in all night exteriors, it isn’t rarely used since it’s a popular approach, and saying it’s never used indoors is off-topic since low-key lighting is also common indoors for mood and contrast.
