LED Panel Lights

LED Panel Light Sizes and Configurations

LED panel lights are built for drop ceilings and commercial interiors that need clean, even light without fluorescent tubes or bulky troffer maintenance. The two standard sizes are 2x2 and 2x4. A 2x2 panel works well in smaller offices, exam rooms, corridors, and grid layouts where fixture spacing is tighter. A 2x4 panel produces more total light and is common in open offices, classrooms, retail spaces, and large work areas.

Panels can be edge-lit or back-lit. Edge-lit panels use a light guide to spread LED output across the face of the fixture, creating a slim profile and smooth appearance. Back-lit panels place LEDs behind the lens and often provide strong efficiency with a simple fixture design. Either style can work when the lumen output, glare control, driver quality, and installation method match the room.

Wattage-Selectable and Color-Selectable Technology

Selectable panels help contractors cover multiple rooms with fewer SKUs. A wattage switch lets the installer choose output for the space, while a CCT switch commonly provides 3500K, 4000K, or 5000K options. Use warmer neutral light in reception areas, 4000K for most offices and classrooms, and 5000K where crisp task visibility is more important than a softer look.

What to Check Before Ordering LED Panel Lights

Start with ceiling type, grid size, existing fixture count, voltage, control system, and required light level. A direct 2x2 or 2x4 replacement is often straightforward, but surface-mount kits, suspension kits, or emergency drivers may be needed when the ceiling is not a standard T-grid or when the room must meet egress-lighting requirements.

• Dimming: Confirm whether the project needs 0-10V dimming, phase dimming, or non-dimming drivers.
• Emergency backup: Offices, schools, healthcare spaces, and corridors may require emergency battery backup on selected fixtures.
• Glare control: Choose diffusers and lumen packages that meet the room's visual-comfort needs.
• Rebate eligibility: DLC-listed panels may qualify for utility rebates depending on your location and program rules.
