Halogen lighting is a variant of incandescent lighting which offers a warm light in comparison with that generated by fluorescent tubes, as well as greater efficiency than conventional filament bulbs. 

They can operate at both mains and low voltage. Electronic transformers are typically used for low voltage operation because they come with smaller dimensions, reduced weight and have higher energy efficiency than conventional transformers.
ST provides all active components to enable a highly efficient electronic transformer:
  • Bipolar Power Transistors
  • Ultrafast Rectifiers
  • Thyristors and AC Switches
