Until now halogen-type lamps could only polymerize by producing a great deal of heat for few efficient wavelengths (on average 500mW/cm² in the utilizable wavelength).
The maximum emitting spectrum of halogen lamps (over 480nm) is not relevant to the optimal absorption zone of the photo-initiators used in dentistry (approx. 430 to 470nm).

The latest generation L.E.D. (Light Emitting Diode) curing lights offer all that is expected of this new technology and the most recent design developed by Satelec® combines power, efficiency and speed:

  • its power (1,250mW/cm²) is greatly superior to that of most halogen lamps and nearly as efficient as plasma lamps, without raising the temperature;
  • it emits light in the most efficient part of the spectrum, suiting all types of composites currently available: camphorquinone (470nm), PPD or PAB (430nm);
  • it takes only 6 to 12 seconds to polymerize 3mm of any composite !
