Composite depth of cure and LED dental curing lamp characteristics
 

Table 2: LED curing lamp spectral characteristics: Measured and according to manufacturers

Comments Table 2: According to the curing lamp standard ISO 10650-2, the measured irradiance value should be no less than that given by the manufacturer. Measured irradiance values (± 9%) that are higher or lower than the corresponding values given by the manufacturer are indicated. Light emission area diameters given by the manufacturers are presented in Table 1.

― Not measured

(A) According to the lamp manufacturer, use of the “parallel-walled” optic light guide will reduce the light intensity with about 50% compared with the 7 mm diameter light guide.

(B) Irradiance was measured with or without the cover part and without the disposable tip attached. The disposable tip will reduce the irradiance.
