FAQ:

Q: What is a low volt transformer?

A: A low voltage transformer is an electrical device that transforms 120 volts (line voltage) into 12 volts or 24 volts (low voltage). Conventional low voltage transformers, also called magnetic low voltage transformers, can be extremely large and heavy, consisting of an iron core and two sets of wires.

Q: What is a 12V adapter?

A: A 12V (12 Volt) adapter is a certain power supply that could be plugged into the utility socket, at 110–220 volts AC, and provide 12 V output.

Q: What is 12V led?

A: 12V DC LED Light Bulbs are a special type of light bulb intended for solar power application, boat lighting, automotive lighting, and RV lighting. 12V DC bulbs are wired so that they can take direct current from a 12V battery and use it for illumination.

Q: What is a 110 volt plug?

A: Any device that says it runs on 110 volts can be plugged into a 120-volt outlet. The “120 volt” label is just a nominal figure; the actual voltage could be anywhere in the range of 110-125 volts, and modern electrical devices are built to tolerate the fluctuations.
