LED Curing Lights True innovation proves itself in use. A perfect example of this is the bluephase curing light with the specially developed polywave LED. bluephase is not only the best-selling LED polymerization light in Europe, but it is also frequently used in clinical and scientific studies* and has been ranked top curing light by independent and renowned test institutes. The polywave LED lights achieve an optimal broadband spectrum of 385 to 515 nm, similar to the spectrum of halogen lights, which served as their model. All bluephase curing lights are therefore suitable for polymerizing the entire range of photoinitiators and materials currently used in dentistry. Every material, every indication, every time and now comfortable to fit every hand ? only this combination gives you the licence to cure.
