RAB SWISH AIR LED Troffer — 2x2 / 2x4 / 1x4 — 18–44W Selectable — 3500K/4000K/5000K — WhiteThe RAB SWISH AIR is a family of slim, high-efficiency recessed LED troffers engineered for commercial T-grid ceilings that require integrated HVAC return-air functionality and premium illumination from a single fixture. Available in 2×2, 2×4, and 1×4 sizes, with or without air-return vents, and with optional PIR sensor, MVS occupancy controls, or 90-minute emergency battery backup. Wattage and CCT are both field-selectable via onboard switch — no tools required. All models operate on 120–277V with a 0–10V dimming driver, are UL Listed for dry and damp locations, and are DLC 5.1 Listed. Backed by a 5-year RAB warranty and rated for 100,000 hours (L70).Key Features Selectable Wattage: Field-adjustable via onboard switch, no tools required — 2×2: 18W/26W/35W · 2×4: 26W/35W/44W · 1×4: wattage steps per model. Selectable CCT: 3500K / 4000K / 5000K — field-adjustable via onboard switch across all sizes and configurations, factory default 4000K. Air Return Integration: “With Vents” configurations allow the fixture to serve as a ceiling-integrated HVAC return-air diffuser — eliminates a separate return-air grille in the same T-grid opening. Efficacy & Output: Up to 140 lm/W · 2×2 peak: 4,702 lm at 35W · 2×4 peak: 6,048 lm at 44W. CRI 82–84 across all configurations. 0–10V Dimming: Dims to 10% minimum — compatible with commercial lighting control systems. Voltage & Driver: Class 2 constant current, 120–277V, 50/60Hz. 2kV surge protection standard. Location Rating: UL Listed for dry and damp locations. Rated Life & Warranty: 100,000 hours (L70) · 5-year RAB warranty covering light output, color stability, driver performance, and fixture finish. Optional Controls & Emergency: PIR occupancy sensor, MVS multi-level vacancy sensor, and 90-minute emergency battery backup (BLLF 0.23) available as factory-installed options.
