Question 1

Which lighting technique places a fixture close to a wall or vertical surface to reveal texture and surface detail?

Accepted Answer

Grazing

Answer

Grazing positions a fixture very close to a textured surface at a steep angle to emphasize its texture and depth.

Question 2

What is the primary reason to use low-voltage landscape lighting systems (12V) rather than line voltage (120V) in residential gardens?

Accepted Answer

Reduced shock hazard and easier DIY installation

Answer

12V systems present a much lower shock hazard and do not require conduit burial, making them safer and easier for residential landscape applications.

Question 3

When illuminating a tree using the uplighting technique, where should the fixture ideally be aimed?

Accepted Answer

Into the canopy to illuminate foliage from below

Answer

Uplighting fixtures are aimed into the canopy to cast light through the foliage, creating a dramatic effect from below.

Question 4

Which IP rating is the minimum recommended for landscape fixtures installed in areas subject to direct rain exposure?

Accepted Answer

IP65

Answer

IP65 indicates the fixture is dust-tight and protected against water jets, making it suitable for direct rain exposure.

Question 5

A client wants to create a 'moonlighting' effect in their backyard. Which installation approach achieves this?

Accepted Answer

Mounting fixtures high in trees aimed downward through branches

Answer

Moonlighting mounts downward-aimed fixtures high in trees to mimic the soft, dappled light of the moon filtering through foliage.
