The RAB SWISHFA2X4/D10 is a 2x4 LED troffer designed for suspended grid ceiling installations in commercial and institutional buildings. This fixture replaces traditional fluorescent troffer lamps with an energy-efficient LED light source, reducing maintenance cycles and operating costs. It is sized for standard 2-foot by 4-foot drop-ceiling grid openings and weighs 25.5 pounds. Electricians and lighting contractors install this unit in office spaces, schools, retail environments, and similar interior applications where uniform, high-quality ambient illumination is required.
This troffer is suited for new construction and retrofit projects in suspended T-bar grid ceilings. Its flat-panel form factor integrates cleanly into standard 2x4 lay-in grid systems. Typical applications include open-plan offices, corridors, classrooms, and light commercial interiors where consistent overhead lighting coverage is critical. Installation is performed by a licensed electrician in compliance with local electrical codes and NEC requirements.
Designed as an OEM-style replacement or new-installation LED troffer for standard 2-foot by 4-foot suspended grid ceiling systems in commercial and institutional environments.
