Ring Low Light Transformer Technology

Is Ring Low Light Transformer a magnetic or electronic transformer?

What type of Transformer technology is it?

Magnetic:

  1. Laminated/stacked cores (also know as EI type)*
  2. Toroidal cores

Electronic: This transformer type converts the 120 volt current to 12 volts by first increasing the frequency of the current (from 60 Hz to as high as 20,000 Hz).
