A blue-light polymerizing system comprises a xenon arc lamp in which its sapphire window includes a blue-bandpass filter coating. This eliminates any external color filters that would otherwise be necessary for the polymerization of dental composite materials in a patient's mouth. The blue-bandpass filter coating causes the xenon arc lamp to heat an extra 10.degree. C. higher than would otherwise be the case. So a special anode heatsink is fitted in which the front and back halves of each radial fin have been separated, and one of these groups of separated fins has been tilted off normal. Such changes the otherwise laminar airflow through the anode heatsink fins to a turbulent flow that is better able to collect heat and carry it off.
