A troffer has a traditional recessed housing that fits into T-bar ceilings and usually replaces older fluorescent troffers. A flat panel is a slim, edge-lit or back-lit LED panel that offers a modern look with very even light distribution. Panels are thinner and lighter, while troffers maintain a more traditional fixture structure.
Yes. Both options are ideal for replacing 2×2, 1×4, and 2×4 fluorescent troffers. They improve efficiency, eliminate ballast maintenance, and provide brighter, flicker-free illumination. Many retrofit kits let you keep your existing housing if needed.
LED troffers and panels typically reduce energy use by 40 to 70 percent, depending on the model. They also last much longer, reducing service calls and eliminating ballast and lamp replacements.
Yes. Most models include 0–10V dimming and can connect to control options like:
Controls help meet modern energy codes and improve comfort in offices and schools.
They are some of the most common choices for these applications because they offer:
They also help reduce eye strain in long workday environments.
Most fixtures last 50,000 to 100,000 hours, depending on driver quality and heat management. Because they use integrated LEDs instead of tubes, there are no lamps or ballasts to replace. Occasional dusting or lens cleaning is usually all that’s needed.
