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.

(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.
