Professional Notes

While the ATS4-450 lamp continues to emit visible light beyond its rated life, the germicidal output diminishes over time due to the natural degradation of the quartz envelope and electrode materials. Professional maintenance schedules should therefore include regular lamp replacement based on operational hours, not solely visible illumination.
