The light-emitting device of claim 1, further comprising an on/off switch for switching the light-emitting device into a non-operative mode during the period in which the light-emitting device is operating in the first or the second operating mode. 11. The light-emitting device of claim 1, comprising a controller adapted to interpret the activation of the switch within the monitoring time period to operate the light output according to the first or the second operating mode. 12. The light-emitting device of claim 11 wherein the controller is user programmable and enables a user to determine the monitoring time period. 13. The light-emitting device of claim 1, comprising a user interface adapted to indicate the operating mode at which the light-emitting device is operating. 14. The light-emitting device of claim 13, wherein the operating mode is indicated by at least one sound. 15. A method of curing a dental material using a light-emitting device that can be operated in a first operating mode and a second operating mode, the method comprising: (a) providing an input on a switch of the light-emitting device; and(b) operating a light output of the light-emitting device in: (i) the first operating mode and not the second operating mode, if the switch is activated during the monitoring time period and subsequently not activated at the end of the monitoring time period; and(ii) the first operating mode and the second operating mode, if the switch is activated during and through the end of the monitoring time period,wherein in both the first and second operating modes the light output emits light of a wavelength and an intensity that cures the dental material. 16. The method of claim 15, wherein in the first operating mode the light output is activated for a first time period and in the second operating mode the light output is activated for a second time period, and wherein the second time period is shorter than the first time period. 17. The method of claim 16, wherein the first time period is between 5 seconds to 20 seconds. 18. The method of claim 16, wherein the second time period is between 0.1 seconds to 5 seconds. 19. The method of claim 15, wherein in the first operating mode the light has a first intensity and in the second operating mode the light has a second intensity, and wherein the first intensity is less than the second intensity.
