High intensive halogen light unit for polymerization of light curing filling material with soft start function for the use in orthodontic, prevention and chair side. With the use of a turbo light tip the light intensity can be achieved over 1.200 mW / cm2 . With an additional soft start phase the polymerization of the materials is controlled and possible tension in the filling material avoided. An orthodontic function with a 5 seconds pulse makes the use in the ortho- dontic field possible. A high light function with 30 seconds pulse is suitable for the prevention and bleaching. With the build-in Radiometer the light output of the lamp can be checked at any time.
