Troffer lights are the workhorse of commercial interior lighting, and for good reason. They drop cleanly into T-bar and grid ceilings, deliver broad, uniform illumination, and disappear into the space so the room stays looking clean and professional. Whether you're outfitting a new build or replacing outdated fluorescent troffer lights with a more efficient LED solution, you'll find the right fixture at Warehouse Lighting. Browse our full selection of LED troffer lights in 1x4, 2x2, and 2x4 sizes, with options for grid mount, surface mount, and suspended troffer light configurations.

Why Troffer Lights Still Dominate Commercial Spaces
Troffer lights fit into modular drop ceiling grids, also called T-bar or suspended ceilings. The name comes from "trough" and "coffer," which describe the recessed housing. They sit flush in the ceiling grid, directing light downward into the space without the visual clutter of exposed pendants or surface-mount strips.
Most commercial buildings you walk into, offices, schools, hospitals, retail spaces, government facilities, are lit with troffers. They're the default for a reason: they're efficient, clean, and well-suited to the kind of broad, even illumination those environments need.
LED vs. Fluorescent Troffer Lights
If you're still quoting fluorescent troffer lights on retrofit jobs, it's worth having the LED conversation with your client. Here's why they should make the switch:
- Energy use: LED troffers use up to 60% less energy than equivalent fluorescent fixtures, which translates directly to lower utility bills.
- Lifespan: Integrated LED troffers are typically rated for 50,000 hours or more, which is considerably longer than standard fluorescent sources.
- Light quality: LED delivers higher CRI and more consistent color temperature throughout the life of the fixture. Fluorescents shift and dim over time.
- Maintenance: Integrated LED fixtures have no tubes to re-lamp and no ballasts to swap out; LED-ready troffer options using LED tubes also dramatically reduce maintenance frequency.
- Rebate eligibility: Many LED troffers in our lineup carry DLC and DLC Premium listings, making them eligible for utility rebates, a strong selling point when helping clients evaluate the total cost of ownership.
Not ready for a full fixture swap? Our LED troffer retrofit kits let you upgrade existing fluorescent housings to LED without replacing the entire fixture, a cost-effective middle ground for occupied spaces.
Troffer Sizes: 1x4, 2x2, and 2x4
- 2x4 troffers are the most common in commercial spaces. They fit standard 2x4 ceiling grid openings and deliver the widest light spread per fixture, making them the go-to for open offices, classrooms, and hallways.
- 2x2 troffers work well in spaces with tighter ceiling grids or where a more modular, architectural look is preferred, such as conference rooms, healthcare exam rooms, and retail environments.
- 1x4 troffers are the right call for narrow corridors, shallow T-bar ceilings, or spaces where a longer, slimmer fixture fits the layout better.
Three Mounting Options
- Grid/lay-in mount: The standard drop-in installation for T-bar ceilings. The fixture rests in the ceiling grid opening.
- Surface mount: For spaces without a drop ceiling, select troffer fixtures can be mounted directly to a hard ceiling surface.
- Suspended/hanging troffer lights: Some models can be hung from the ceiling with chains or cables for an exposed, industrial-meets-commercial aesthetic, or where ceiling height makes surface mounting impractical.
Lens and Diffuser Options
- Center basket: The most common style; bounces light off an internal reflector for diffused, even illumination with a clean appearance.
- Parabolic louvers: Cell-based aluminum louvers that cut glare and provide more directed light output; ideal for computer-heavy offices and spaces where visual comfort is critical.
- Prismatic lens: A classic diffuser lens that scatters light broadly; common in schools and general commercial applications.
- Edge-lit and back-lit panels: Slim-profile options with a more modern, architectural look.
Additional Options
- 0-10V dimming: Available on many models for occupancy and daylight harvesting control integration.
- Emergency battery backup: Available on select fixtures; a must-have for healthcare facilities, schools, and public buildings.
- Wattage-selectable: Multiple models offer field-selectable wattage (e.g., 30W/40W/50W) so one SKU covers multiple layout scenarios on larger projects.
- CCT-selectable: Switch between 3500K, 4000K, and 5000K at the fixture; useful on large projects where preferences vary by space type.

Shop All Commercial LightingFrequently Asked Questions About Troffer Lights
What's the difference between a center basket troffer and a parabolic troffer?
A center basket troffer uses a basket diffuser to bounce light off an internal reflector, producing soft, even illumination. It's the most widely used style in general commercial applications. A parabolic troffer uses aluminum louvers divided into cells to control the direction of light and reduce glare. Parabolic fixtures are the better choice in environments with computer screens or where occupant visual comfort is a priority, such as offices and labs.
Are your LED troffers DLC-listed for utility rebates?
Many are; you'll see DLC and DLC Premium listings noted in the product certifications on individual product pages, and both qualify for rebates through most utility programs.
Do you carry troffer retrofit kits for existing fluorescent fixtures?
Yes. If the housing is in good shape and a full fixture swap isn't in the budget, our LED troffer retrofit kits can convert existing fluorescent troffers to LED without touching the housing. We carry magnetic strip retrofit kits (which magnetically attach directly to the fixture interior; no tools, tombstones, or ballasts needed) and volumetric retrofit kits in 1x4, 2x2, and 2x4 configurations.
