One of the strongest arguments for laser projection is the dramatic reduction in running costs. Both the laser light source and the ECO Filter are rated to approximately 20,000 hours before replacement is needed — a period during which a comparable lamp-based projector would require between one and four lamp changes plus regular filter maintenance. The ECO Filter can be washed and reused up to two times, reducing waste further. There are no expired lamps to dispose of safely, no unplanned downtime for maintenance, and no surprise replacement costs. Laser brightness also ramps up and down in a controlled way, ensuring color reproduction remains consistent and vivid across the full life of the light source. Note: at approximately 20,000 hours, light output will have decreased to about 50% of its original level under reference conditions (DYNAMIC mode, 30 °C, 700 m elevation, 0.15 mg/m³ particulate matter). Actual hours vary by environment.
