RAB SWISHAIR2X2/MVS/E SWISH AIR LED Troffer — 35W/26W/18W Selectable — 3500K/4000K/5000K — Microwave Sensor — Battery Backup — White The RAB SWISHAIR2X2/MVS/E is a 2×2 recessed LED air-return troffer with a factory-installed microwave occupancy sensor and integrated 90-minute emergency battery backup, designed for commercial T-grid ceilings requiring HVAC return-air functionality, occupancy-based energy control, and life-safety code compliance. Wattage is field-selectable between 35W (factory default), 26W, and 18W, and CCT is field-selectable between 3500K, 4000K (factory default), and 5000K — both via onboard switch, no tools required. At peak output, the fixture delivers 4,703 lumens at 35W / 4000K with a peak efficacy of 146.4 lm/W at 18W / 4000K. The SWISHAIR2X2/MVS/E operates on 120–277V with a 0–10V dimming driver and is UL Listed for dry and damp locations and DLC 5.1 Listed as Ultra-Efficient Premium.
