Phoseon Technology, the leader in UV LED curing solutions, today announced a major milestone for UV LED light sources. As a result of Phoseon's rigorous reliability efforts, lifetime testing of lamps has now surpassed 50,000 hours of operational on-time with lamp irradiance being greater than 80% of its original output when the test first began five-plus years ago. For perspective, utilizing a single shift workweek of 2,000 hours per year, 50,000 hours equates to 25 years of UV LED operating on-time.
