2x2 LED Troffer Ceiling Light - Adjustable Lumens & Color

In this review of the 2x2 LED Troffer Ceiling Light from Lithonia Lighting, the bottom line is simple: it is a flexible, energy-efficient upgrade for offices, classrooms, and other dropped ceiling spaces. The single biggest reason to buy is its combination of selectable lumen output and switchable color temperature, which makes it easy to dial in both brightness and ambiance without changing fixtures. The shallow 1.9 in depth and compatibility with standard 15/16 in and narrow 9/16 in T-grid systems also make it an attractive option where plenum depth or installation time matters.

Key Features

• Adjustable Lumens: Three lumen settings (3000, 4000, 5000) let you choose brightness appropriate for different ceiling heights and room tasks in a single fixture.
• Switchable Color Temperature: Easy switches provide 3500K, 4000K, or 5000K options so you can set warm neutral, cool, or daylight tones without needing different fixtures.
• Low Profile Design: At only 1.9 in deep the troffer fits restrictive plenum spaces and installs cleanly in both standard and narrow T-grid ceilings.
• Glare-Reducing Reflector: The wide center basket and curved matte white reflector improve diffusion and reduce glare for more comfortable long-term use in offices and classrooms.
• Durable, Long-Life LEDs: Integrated LEDs are rated for L80/60,000 hours, giving long-term lumen maintenance and lower replacement frequency compared with fluorescent fixtures.
• Safety and Efficiency Certifications: CSA certified, DLC qualified, IC rated, and damp location listed for flexibility across commercial and institutional spaces.

Who It's For

This fixture is aimed at facility managers, school maintenance teams, and small business owners who want a straightforward retrofit from older fluorescent troffers and need selectable light levels and color without stocking multiple SKUs. The switchable settings make it useful where rooms serve multiple functions, such as classrooms that double as exam spaces or meeting rooms.

Those who need decorative pendant lighting, tunable white controls via a building management system, or fixtures for high-humidity outdoor environments should look elsewhere, since this product is a fixed integrated LED troffer with manual switches and is intended for interior dropped ceilings and damp locations rather than wet or outdoor installations.
