Lithonia Lighting 224GP5 Led Troffer 39W 2x4

Product Description

The LITHONIA LIGHTING 224GP5 is a 2-foot by 4-foot LED troffer fixture rated at 39 watts and designed for drop-ceiling grid installations. It operates on 120 to 277 volts and supports dimming, making it suitable for commercial and light industrial spaces where lighting control is required. The fixture ships as a complete unit with a white acrylic diffuser and a steel troffer body. Electricians and lighting contractors install this unit in standard 2x4 lay-in ceiling grids as a direct replacement or new-construction fixture. At 39 watts, it delivers significant energy reduction compared to legacy fluorescent troffer layouts in the same footprint.

This troffer is suited for interior commercial environments including offices, retail spaces, schools, healthcare facilities, and light industrial areas where a 2x4 recessed lay-in fixture is specified. The dimmable 120/277-volt input allows compatibility with a wide range of dimming controls and commercial electrical systems. The white acrylic diffuser provides uniform light distribution across the panel face, minimizing hotspots in open-ceiling grid environments.

Key Features

• LED light source integrated into a 2x4 steel troffer body — no separate lamp required
• 39-watt power consumption suits energy-code-compliant commercial installations
• Dimmable operation compatible with standard commercial dimming controls
• Dual-voltage input (120 to 277 volts) simplifies specification across different electrical systems
• White acrylic diffuser provides even light distribution across the fixture face
• Steel troffer construction for durability in standard lay-in ceiling grid applications

Compatibility

Designed for use in standard 2-foot by 4-foot drop-ceiling grid openings as an OEM-style or replacement LED troffer fixture in commercial lay-in ceiling systems.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements and local codes. De-energize the branch circuit at the panel before handling wiring connections. The fixture is designed for lay-in grid ceilings and should be supported per the ceiling grid manufacturer guidelines — do not rely solely on the grid for support where local code requires independent fixture support. Verify dimmer compatibility with the fixture before final installation.
