Lighting Design & Application Flashcards

Which of the following best describes the three foundational layers of residential lighting design?

Answer: Ambient, task, and accent lighting

Ambient, task, and accent lighting are the three universally recognized layers that together create a complete, functional, and aesthetically balanced lighting scheme.

What does color temperature, measured in Kelvin (K), indicate about a light source?

Answer: The warmth or coolness of the light's appearance

Color temperature describes the perceived warmth or coolness of a light source; lower Kelvin values (2700–3000K) appear warm and yellow, while higher values (5000K+) appear cool and blue-white.

A client wants to showcase a piece of artwork on a feature wall. Which lighting type is most appropriate?

Answer: Accent lighting

Accent lighting is specifically designed to draw attention to and highlight particular features, objects, or architectural elements, such as artwork.

What is the Color Rendering Index (CRI) and why does it matter in decorating?

Answer: A measure of how accurately a light source renders colors compared to natural light

CRI measures how faithfully a light source reveals the true colors of objects compared to natural sunlight; a higher CRI (90+) is critical in decorating to ensure fabrics, paint, and finishes appear as intended.

Which lumen range is generally recommended for ambient lighting in a residential living room of approximately 250 square feet?

Answer: 1,500–3,000 lumens

A living room typically requires 10–20 lumens per square foot for ambient light, placing a 250 sq ft room in the 2,500–5,000 range; 1,500–3,000 lumens covers a moderate, comfortable ambient level.

What is 'layered lighting' in interior decorating?

Answer: Combining ambient, task, and accent light sources to create depth and flexibility

Layered lighting refers to the deliberate combination of ambient, task, and accent sources to achieve a versatile, dimensionally rich environment that can be adjusted for different moods and functions.

Which type of lighting fixture is best suited for providing task lighting over a kitchen island?
