RAB SWISHAIR2X2 SWISH AIR LED Troffer — 35W/26W/18W Selectable — 3500K/4000K/5000K — White

The RAB SWISHAIR2X2 is a 2×2 recessed LED air-return troffer designed for commercial T-grid ceilings requiring integrated HVAC return-air functionality. 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 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. Replaces conventional fluorescent 2×2 troffer fixtures.

Smart & Control Features

The SWISHAIR2X2 supports 0–10V dimming as standard and is available with four factory-installed occupancy sensor configurations:

• Standard (0–10V): Dims to 10% minimum via 0–10V DC circuit — compatible with standard commercial building controls.
• PIR (/PIR suffix): Factory-installed Passive Infrared sensor. Detection range: 20 ft diameter at 9 ft mounting height. Max mounting height: 9–12 ft.
• Microwave (/MVS suffix): Factory-installed microwave sensor — detects motion through walls and partitions. Detection range: 20 ft diameter at 9 ft mounting height. Max mounting height: 9–12 ft.
• Lightcloud Blue PIR (/LCBS suffix): Wireless Bluetooth mesh PIR sensor — no 0–10V circuit required.
• Lightcloud Blue MVS (/LCB/MVS suffix): Wireless Bluetooth mesh microwave sensor — no 0–10V circuit required.

Sensor defaults: Motion Sensitivity High · 100% brightness when triggered · 20-min hold time · 20% standby dim · 1-min standby time · Daylight Disabled. Adjustable via Lightcloud Blue app (Lightcloud Blue models) or MSR1 remote accessory (sold separately).
