HILLSBORO, OR – Phoseon Technology, a leader in UV LED curing solutions, 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 percent of its original output when the test first began five-plus years ago. For perspective, utilizing a single-shift work week of 2,000 hours per year, 50,000 hours equates to 25 years of UV LED operating on-time.

Phoseon maintains over 50 UV LED curing lamps in various stages of lifetime testing at any given time. These light sources are stressed with decreased airflow, high temperatures and other parameters that mimic the harsh working conditions of industrial UV LED curing equipment.
