Read the first 7 Outdoor & Landscape Lighting flashcards as text

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

    Answer: Grazing

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

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

    Answer: Reduced shock hazard and easier DIY installation

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

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

    Answer: Into the canopy to illuminate foliage from below

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

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

    Answer: IP65

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

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

    Answer: Mounting fixtures high in trees aimed downward through branches

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

  6. What color temperature range is generally preferred for residential landscape lighting to achieve a warm, inviting appearance?

    Answer: 2700–3000K

    2700–3000K produces a warm white light that enhances plant colors and creates an inviting atmosphere in residential landscapes.

  7. Which control strategy is most effective for automatically adjusting outdoor landscape lighting to seasonal changes in sunset time?

    Answer: Astronomical (solar) time clocks

    Astronomical time clocks calculate local sunrise and sunset times based on GPS coordinates and date, automatically adjusting on/off times year-round.
