Question 1

What does 'dimming capability' in a landscape lighting transformer allow an installer to do?

Accepted Answer

Adjust the brightness output of compatible LED fixtures

Answer

Reduce the number of fixtures connected to a single circuit

Answer

Lower the transformer's primary voltage to reduce energy costs

Answer

Decrease the cable gauge requirement for a run

Question 2

Which type of motion sensor is most commonly integrated into outdoor landscape lighting control systems?

Accepted Answer

Passive infrared (PIR) sensor

Answer

Ultrasonic sensor

Answer

Microwave radar sensor

Answer

Laser tripwire sensor

Question 3

In landscape lighting control, what does 'scene programming' allow?

Accepted Answer

Presets that control multiple zones to specific brightness levels simultaneously with one command

Answer

Programming the color temperature of each individual fixture

Answer

Recording a video of the landscape to use as a reference

Answer

Setting the maximum wattage per circuit automatically

Question 4

What is the purpose of a 'soft start' feature found on some landscape lighting transformers?

Accepted Answer

It gradually increases voltage at startup to reduce inrush current and extend lamp life

Answer

It silences the audible buzzing on magnetic transformers

Answer

It prevents voltage fluctuations from dimming circuits during a power surge

Answer

It limits the total connected wattage to 80% of the transformer rating

Question 5

When setting up a photocell and timer together on a landscape lighting system, what is the typical best practice for operation?

Accepted Answer

Use photocell to turn on at dusk, and timer to turn off at a set time

Answer

Use timer to turn on at a fixed hour and photocell to turn off at midnight

Answer

Use two separate photocells for redundancy and disable the timer

Answer

Set the timer to override the photocell during daylight hours

Question 6

What is 'load shedding' in the context of a smart landscape lighting controller?

Accepted Answer

Removing low-priority lighting zones during a peak energy demand period to reduce power consumption

Answer

Automatically disconnecting overloaded circuits to prevent transformer damage

Answer

Shedding corrosion from fixture contacts before installation

Answer

Turning off all zones simultaneously after a programmed duration

Question 7

Which feature in a modern landscape lighting control system allows the intensity of lights to change at specific times of night?

Accepted Answer

Time-based dimming or scheduled dimming

Answer

Sunset mode

Answer

Photocell calibration

Answer

GFCI scheduling
