A dental light having an array of light emitting diode (LED) assemblies, at least one first LED assembly having at least one first LED element configured to emit light according to a first spectral distribution, a conversion phosphor configured to convert at least a portion of the first spectral distribution. At least one filter is fixed within said converted light, the filter configured to block at least a portion thereof. The array includes at least one second LED element configured to emit light according to a second spectral distribution, wherein light having the filtered spectral distribution is selectively emitted from said array in a first mode and from both the filtered and second spectral distributions in a second mode.
