Frequently Asked Questions (FAQs)
1. Can low voltage transformers be mounted indoors?
◗ All power supplies are indoor and outdoor rated, but we recommend that the transformer be mounted outdoors. If mounted indoors, then codes should be followed that apply to indoor wiring - especially for wires that pass through exterior walls.
2. What transformer is needed for low voltage lighting?
Transformers generally range from 150- to 900-watt capacity. Matching the size of the transformer to the lighting design is important for efficient operation and function of the system. House current, 120 volts, is reduced by a transformer to 12 to 20 volts, the current needed to operate low-voltage landscaping lights.
3. Do all low voltage transformers work with LED lights?
No, low voltage AC lighting is not just used in landscape lighting to try and spite all those switching to LEDs. It was actually used in many old systems as it was much easier to create a 12VAC transformer compared to a DC transformer and incandescent bulbs could care less about AC or DC power.
4. Do low voltage LED lights need a transformer?
Low voltage halogen bulbs and some LED lights require the use of an additional electronic device known as a transformer (for halogen bulbs) or a driver (for LED lights). Both of these devices reduce the AC voltage from the mains supply to a much lower level but this is generally where the similarities end.
