Applications

High-bay HID pendant fixtures like the Ruud Lighting IAR-22 Series are standard equipment in large-volume commercial and industrial spaces where high ceilings (typically 20–45 feet) require powerful, focused downlighting. Common installations include warehouses, distribution centers, manufacturing floors, gymnasiums, and big-box retail spaces. The 400-watt pulse start metal halide lamp type offers faster warm-up and restrike times compared to standard probe-start metal halide, making it well suited for facilities with frequent switching or where quick light recovery after a power interruption matters. The prismatic polycarbonate reflector provides broad light distribution across wide floor areas. This fixture type was widely deployed from the 1990s through the 2000s and remains in service in many facilities, though LED high-bay replacements have become increasingly common in new installations.
