A dental system includes a light source, a power supply that adjusts a quantity of light produced by the light source, a measuring device that measures a quantity of light received from the light source, an input, through which user data, including a desired quantity of light, can be entered, and a controller which, together with the measuring device, forms at least part of a feedback loop. The controller receives the user data and communicates with the measuring device and the power supply so that the power supply adjusts a quantity of light emitted by the light source. As a result, the quantity of light received from the light source becomes substantially equal to the desired quantity of light.
