GE Lightech 66954 • 75W Dimmable
Halogen Low Voltage Electronic Transformer / 12V 6.25A Output / 277V

  • Employs patented auto-thermal regulation
  • Proportional dimming of output voltage over 194°F (90°C) and self-preserving 257°F (125°C) thermal cut-off
  • Embedded Lightech technology ensures transformers run cool with a higher efficiency of 95% at full load
  • Can be dimmed by low cost TRIAC dimmers without producing any acoustic noise
  • Field effect transistors provide higher efficiency compared to common bipolar transistors
  • High efficiency allows for both smaller size and longer life
