The present invention relates to a curing light suitable for curing light curable dental composite materials. The curing light device has a light module housing having at least one heat sink located therein. The heat sink has at least two mounting platforms arranged in different geometric arrangements. More than two light sources may be used, emitting at least two different wavelengths. The curing light includes at least one heat sink having various geometric shapes, which facilitate the arrangement of the light sources in the curing light and minimizing the concentration.
