Product: 2x4 LED Panel Light with Emergency Battery Backup - 2329-3922 Lumens - 17W–30W Selectable Wattage - 3CCT Selectable - 120-277V

The RAB Lighting T34FAHE-2X4/E is a 2x4 LED panel light engineered for commercial and institutional applications requiring integrated emergency backup illumination. This recessed troffer combines selectable wattage (17W, 22W, or 30W) with three-color temperature options and dual-voltage operation (120–277V), making it adaptable to standard or premium lighting environments across diverse commercial buildings.

The fixture delivers 2,329 to 3,922 lumens depending on wattage selection, with built-in emergency battery backup that maintains safe illumination during power interruptions. The modular design accepts standard 2x4 troffer openings, simplifying retrofit and new construction installations. Selectable color temperatures allow facility managers to match existing lighting schemes or establish consistent visual environments. The emergency feature uses an integral battery system that charges during normal operation, ensuring egress and task lighting continuity without requiring external equipment.

This panel light serves offices, retail spaces, warehouses, educational facilities, healthcare settings, and other commercial properties where code-compliant emergency lighting enhances safety and operational continuity. The selectable wattage permits energy optimization across different ceiling heights and illumination requirements, while the 120–277V rating accommodates both standard and three-phase distribution systems common in larger commercial facilities.

The combination of emergency backup, color temperature flexibility, and adjustable output makes this fixture practical for main-floor and corridor applications where reliable illumination and compliance matter equally. Installation fits standard suspended-ceiling infrastructure without additional structural modifications or separate emergency lighting circuits.
