Frequently Asked Questions
Can I use a 300W transformer for both LED and halogen lights?
Yes most modern 300W transformers are compatible with both LED and halogen bulbs. Ensure that the total wattage of all connected lights does not exceed the unit's capacity to prevent overloading.
What happens if the voltage drops too low in my landscape system?
If voltage drops your lights may appear dim. Using a transformer with adjustable voltage taps allows you to boost the output to compensate for wire resistance and maintain brightness.
Does the photocell sensor work indoors or in covered areas?
The sensor detects ambient light so it may not work indoors or in covered areas. For these locations you should override the sensor using the manual or timer mode settings.
How do I know if the transformer is ETL listed?
Check the product specifications or labeling on the unit. ETL listed items will have a visible logo indicating they meet safety testing standards for electrical devices.
Can I add more lights later if I buy a 300W unit?
You can add lights as long as the total wattage remains within the transformer's capacity. Calculate the sum of all fixture wattage to ensure you stay below the 300W limit.
Why is my transformer tripping or shutting off?
This usually indicates an overload or a short circuit in the wiring. Check for faulty bulbs or exposed wires and ensure you are not exceeding the rated capacity of the unit.
