14 / 17 / 20 / 28 Watt Adjustable 2x2 Troffer Light | 1979 to 3845 Lumens | 3000K / 3500K / 4000K / 5000K / 6500K Adjustable | 100-277V

Product Overview

This 2x2 LED troffer delivers adjustable wattage and color temperature in a single fixture. Wattage can be set to 14, 17, 20, or 28 watts, producing between 1,979 and 3,845 lumens depending on the selected output. Color temperature is adjustable across five settings: 3000K, 3500K, 4000K, 5000K, and 6500K.

The fixture ships configured to 28 watts and 4000K. Adjustments are made on the fixture itself prior to installation or during maintenance. The aluminum alloy housing measures 23.75 inches by 23.75 inches by 2.13 inches and weighs 11.4 pounds. A polycarbonate lens diffuses light across a 120-degree beam angle.

This troffer operates on 100-277V input at 50 or 60 Hz and supports 0-10V dimming. Rated lifespan is 50,000 hours. The fixture is designed as a direct replacement for fluorescent troffers in standard 2x2 recessed grid ceilings.

Where This Product Fits Best

This fixture fits standard 2x2 recessed ceiling grids and replaces fluorescent troffers without modification to the grid opening. The recessed mounting method suits suspended ceiling systems commonly found in offices, classrooms, healthcare facilities, and retail backrooms.

The operating temperature range of -4°F to 122°F allows installation in climate-controlled interiors as well as spaces with limited HVAC coverage. The 100-277V input handles standard commercial voltages across single-phase systems. At 11.4 pounds, the fixture is within typical weight tolerances for suspended grid ceilings.

Performance and Functional Considerations

Output ranges from 1,979 lumens at 14 watts to 3,845 lumens at 28 watts. Efficacy remains consistent at 140 lumens per watt across all wattage settings. This allows output to be matched to task requirements or existing light levels without changing the fixture model.

Color temperature selection spans warm (3000K) through daylight (6500K). This range supports applications where color appearance affects occupant comfort, visual tasks, or aesthetic requirements. CRI is rated at 80 or higher across all color settings.

The 0-10V dimming input is compatible with building management systems and wall-mounted dimmers that use the same protocol. Dimming allows further output reduction below the lowest fixed wattage setting when connected to a compatible control.

Installation and Long-Term Use

The fixture installs in standard 2x2 recessed grid openings. Wattage and color temperature are selected using switches or controls on the fixture body before final placement in the ceiling. Once installed, these settings remain fixed unless the fixture is accessed again.

The aluminum alloy housing supports long-term durability in interior commercial environments. The 50,000-hour rated lifespan reduces relamping frequency compared to fluorescent systems. The white fixture finish blends with standard ceiling grid systems.

How This Fixture Is Commonly Used

Facilities typically set wattage based on the light level needed in each space. A private office or low-traffic corridor may run at 14 or 17 watts, while open workspaces or conference rooms may require the full 28-watt output. This adjustment is made once during installation and left in place.

Color temperature is selected based on the function of the space or occupant preference. Warmer settings like 3000K and 3500K are common in patient rooms, lobbies, and hospitality areas. Cooler settings like 5000K and 6500K are typical in task-oriented environments such as exam rooms, laboratories, or retail sales floors.

When connected to a 0-10V dimmer, the fixture can be adjusted by occupants or scheduled through a building automation system. This is common in daylight harvesting applications or spaces with variable occupancy throughout the day.
