The Q-Lab Q-SUN XE-3-HS is a full-sized xenon arc chamber for accelerated weathering and light stability testing. Three 1800 W ozone-free xenon arc lamps deliver full-spectrum illumination that replicates outdoor sunlight exposure. The patented SOLAR EYE® Irradiance Control System automatically maintains programmed light intensity at 340 nm, 420 nm, or TUV (300–400 nm) wavelengths. By combining controlled irradiance, temperature, and humidity, the chamber compresses months or years of environmental degradation into days or weeks, enabling rapid material durability assessment without natural weathering timelines.
