RAB Lighting C-SWISH Field Adjustable LED Troffer — 1x4, 2x2 & 2x4, Selectable Wattage & CCT, Standard / Battery Backup / Microwave Sensor, 120-277V, White

The RAB Lighting C-SWISH is a slim, high-efficiency center-basket LED troffer engineered for modern commercial drop ceilings. Available in three sizes — 1x4 (C-SWISH1X4), 2x2 (C-SWISH2X2), and 2x4 (C-SWISH2X4) — and in four configurations — Standard, Battery Backup (/E), Microwave Sensor (/MVS), and Battery Backup + Microwave Sensor (/E-MVS) — all models feature field-selectable wattage, selectable 3500K/4000K/5000K CCT, and 0-10V dimming on a universal 120-277V input. The distinctive center-basket frosted polycarbonate lens delivers smooth, volumetric, glare-free illumination with 85 CRI and up to 142 LPW. All models are IC-rated, damp location listed, and carry a 100,000-hour L70 lifespan with a 5-year warranty.

RAB C-SWISH Features

• Center-Basket Polycarbonate Lens: The signature C-SWISH design — a frosted polycarbonate center-basket profile delivers smooth, volumetric illumination that eliminates harsh glare in screen-intensive office and retail environments.
• Field-Selectable Wattage: 1x4 & 2x2: 30W/25W/20W; 2x4: 40W/30W/20W — set on-site to match illumination and energy targets without rewiring.
• Selectable CCT: Field-adjustable 3500K, 4000K, and 5000K color temperatures via on-driver switch for precise ambiance control.
• Four Configuration Options: Standard (general use), Battery Backup (/E, 90-min emergency egress), Microwave Sensor (/MVS, integrated occupancy control), or Battery Backup + Microwave Sensor (/E-MVS, full life safety + automation).
• Integrated Microwave (MVS) Occupancy Sensor: Available on /MVS and /E-MVS models — detects occupancy through partitions and walls for reliable auto-on/off in restrooms, corridors, and private offices.
• 90-Minute Battery Backup: Available on /E and /E-MVS models — automatically activates during power failure for NEC/IBC-compliant egress lighting. Requires unswitched hot supply line.
• IC-Rated: Safe for direct contact with insulation in recessed ceiling applications — no clearance required.
• Damp Location Listed: UL listed for use in standard environmentally controlled interior spaces.
• 0-10V Dimming: Dims to 10% for compatibility with daylight harvesting sensors and commercial energy management systems.
• Universal Voltage: 120-277V input — no external transformer required for standard commercial grids.
• 100,000-Hour Lifespan: L70-rated LED life with a 5-year warranty minimizes maintenance in commercial installations.
• 2.94” Slim Profile: Consistent depth across all three sizes for clean integration into standard T-bar drop ceiling grids.

90-Minute Battery Backup (/E & /E-MVS Models)

Battery Backup models include an integrated emergency battery system that automatically activates during a power failure, operating the fixture at a reduced lumen level for a minimum of 90 minutes to support safe building evacuation. These models comply with NEC and IBC emergency egress lighting requirements. Important: An unswitched hot supply line must be connected to maintain battery charge. Minimum starting temperature for battery backup models is 32°F (0°C).

Integrated Microwave Occupancy Sensor (/MVS & /E-MVS Models)

Microwave Sensor models include an integrated MVS occupancy sensor that detects motion through partitions, cubicle walls, and standard interior walls — providing reliable auto-on/off control in spaces where line-of-sight PIR sensors fail. Ideal for restrooms, private offices, corridors with partitions, and conference rooms. The sensor operates independently of the 0-10V dimming circuit.

Typical Applications

• Commercial offices and open workspaces.
• Retail environments and hospitality corridors.
• Educational institutions and classrooms.
• Healthcare facilities and medical offices.
• Restrooms and private offices (MVS sensor models).
• Egress corridors and stairwells (Battery Backup models).
• Retrofit and new construction T-bar drop ceiling installations.

Performance & Light Output

All C-SWISH models deliver up to 142 LPW (2x4) and 138 LPW (1x4 & 2x2) with 85 CRI through the signature center-basket frosted polycarbonate lens for smooth, volumetric, glare-free illumination. The 100,000-hour L70 lifespan dramatically reduces re-lamping and maintenance costs versus legacy fluorescent troffers.

Electrical & Controls

Each model is powered by a high-efficiency driver operating on 120-277V AC. All configurations include 0-10V dimming leads (dims to 10%) for compatibility with daylight harvesting sensors and commercial energy management systems. Battery Backup models require an unswitched hot supply line to maintain battery charge. MVS sensor models operate independently of the 0-10V dimming circuit.

Construction & Durability

The 2.94” slim profile polypropylene housing is finished in white for clean integration into standard T-bar drop ceiling grids. IC-rated for direct insulation contact. Damp location listed and UL certified for standard interior commercial environments. Standard models operate from -4°F to 113°F; Battery Backup models from 32°F to 113°F.

Installation & Mounting

All models are designed for rapid drop-in installation into standard T-bar ceiling grids — no additional hardware required. IC-rated for direct insulation contact without clearance. Battery Backup models require an unswitched hot supply line for proper battery charging. Optional surface mount kits are available separately for drywall hard ceiling installations.
