RAB C-SWISH LED Troffer — Field-Adjustable Wattage & CCT, up to 4,884 lm, 3500K–5000K, 120–277V, DLC Premium / DLC Listed

The RAB C-SWISH is a family of recessed LED troffers available in three form factors — 1×4, 2×2, and 2×4 — each with field-selectable wattage and field-selectable CCT for precise, on-site output tuning without stocking multiple SKUs. All models operate on 120–277V universal voltage with 0–10V dimming, are UL Listed for damp locations, and carry DLC certification qualifying for utility rebates. Four control and safety configurations are available per size: Standard, Battery Backup (/E), Microwave Sensor (/MVS), and Microwave Sensor with Battery Backup (/MVS/E).
