The present invention relates to a dental curing light adapted to provide radiation output having a light intensity of at least 1000 mW/cm2, the radiation output comprising a first peak in the electromagnetic radiation spectrum in the range of from 395 to 410 nm, a second peak in the range of 450 to 470 nm, the dental curing light comprising: (a) at least one solid-state light source units adapted to emit primary radiation having a peak in the range of from 395 to 410 nm, each solid-state light source unit having a light emitting outer surface; (b) a first layer covering at least a portion of the outer surface of each of the one or multiple solid-state light source units, the first layer comprising a first particulate phosphor absorbing a part of the primary radiation and converting the primary radiation into a secondary radiation having a different wavelength by fluorescing with a peak in the range of from 450 to 470 nm and/or 420 to 440 nm, the first particulate phosphor being dispersed in a continuous phase transparent to the primary and secondary radiation peaks, the first layer having a light emitting outer surface; (c) an encapsulant layer of transparent resin covering the outer light emitting outer surface, wherein the at least one solid state light source units are facing the input end of a light guide or a lens facing the tooth surface, and wherein the intensity ratio of the first and second peaks is adjusted to a ratio of 1:3 to 1:4.
