Product: 1x4 LED Panel Light with Emergency Battery Backup - 2137-4089 Lumens - 20W–40W Selectable Wattage - 3CCT Selectable - 120-277V

The RAB Lighting T34FA-1X4/E is a 1x4 LED panel light engineered for commercial environments requiring flexible illumination with integrated emergency egress capability. This recessed troffer fixture delivers between 2,137 and 4,089 lumens through selectable wattage operation at 20W, 30W, or 40W, allowing facility managers to optimize light output and energy consumption based on specific space requirements. The fixture operates across 120–277V circuits, accommodating standard North American commercial electrical systems without ballast compatibility concerns.

The built-in emergency battery backup enables the fixture to provide minimum illumination during power loss, supporting code-compliant emergency egress lighting in corridors, stairwells, and exit pathways. Three selectable color temperature options—typically 3000K, 4000K, and 5000K—enable matching ambient lighting in offices, retail spaces, and industrial facilities without fixture replacement. The 1x4 form factor fits standard 2x4 foot ceiling grid systems common in suspended drop-ceiling installations, simplifying retrofit applications in existing commercial buildings.

This panel light suits office buildings, retail environments, warehouses, educational facilities, and healthcare settings where both task illumination and emergency lighting functionality are required. The wattage selection capability reduces operational energy costs in spaces with variable occupancy or daylighting availability, while the emergency backup feature eliminates the need for supplemental dedicated emergency fixtures in many applications. Selectable color temperature supports diverse design standards across different commercial departments and operational zones.
