Constant light intensity. The solidification effect is not affected by the consumption of remaining power. Industrial design patent No.: CN 201 130176281.3 Power input：AC100V-240V 50Hz/60Hz Light output：1000 mW/cm²- 1200 mW/cm² Net weight：178 g Dimensions：252 mm × Ф25 mm Wavelength：385 nm - 515 nm ## Newly Upgraded For Wide Spectrum Upgraded wide spectrum The emission wavelength range of Led. H wide spectrum curing light is 385 nm- 515 nm,mainly adding the wave band of 385 nm-420 nm. The additional band can better curing the resin materials containing new-style photoinitiators suchas TPO . For example,restoration materials such as Tetric N-Ceram Bulk Fill (Ivoclar ) ,Amelogen plus (Ultradent ),and ENA Hri (Micerium ).The additional wave band can also reduce the risk of resin shedding and incomplete curing. .LED.H Spectral Curve and Resin Spectral Absorptivity The light-absorbing peak of traditional material (including camphorquinone;the red line on the fifigure) is 460 nm, so the curing can be done by either general Curing Light or Wide Spectrum Curing Light. But camphorquinone is of a yellow color. It is not suitable to add large amounts of it to bleaching resin or light-colored resins. The light-absorbing peak of new materials(including TPO;the blue line in the fifigure above) is 405nm. Compared with general LED Curing Light, Led. H owns additional 385nm- 420nm wave band which is able to better curing this kind of new material. TPO is of white color. Thus it is suitable for adding to the bleaching resin and light-colored resin.
