LLC Landscape Lighting Design & Placement 2

Question 1

When uplighting a tree with a narrow canopy, where should the fixture typically be positioned?

Accepted Answer

3–5 feet away from the trunk angled inward

Answer

Positioning fixtures 3–5 feet from the trunk and angling them inward illuminates the canopy without creating a harsh 'flashlight' effect at the base.

Question 2

Which lighting technique is most appropriate for emphasizing the texture of a brick or stone wall?

Accepted Answer

Grazing

Answer

Grazing places a fixture very close to the surface at a steep angle, casting shadows that accentuate texture and surface relief.

Question 3

A client wants to highlight a focal plant at the end of a long garden path. What spacing principle best guides path light placement along the way?

Accepted Answer

Space fixtures so pools of light slightly overlap

Answer

Slightly overlapping light pools prevent dark spots and create a safe, continuous visual guide along the path.

Question 4

What is the primary purpose of 'cross-lighting' a sculpture or specimen plant?

Accepted Answer

To reveal three-dimensional form by lighting from two angles

Answer

Cross-lighting from two opposing angles creates depth and dimensionality by balancing shadows on either side of the object.

Question 5

When designing a lighting plan for a sloped property, which factor most affects fixture aiming angles?

Accepted Answer

Grade change and viewing elevation

Answer

Grade changes alter the relationship between fixture height and target, requiring aiming angle adjustments to avoid over- or under-illumination.
