LED Flat Panel Lights

Flat LED panels drop into a standard ceiling grid to replace fluorescent troffers in offices, schools, healthcare, and retail. The format you pick - 2x4, 2x2, or 1x4 - matches the grid opening, while backlit or edge-lit construction sets light quality and panel depth. Most run on 0-10V dimming with selectable wattage and color temperature. Lumera Electric supplies them by the pallet for commercial fit-outs.

What size LED panel do I need — 2x4, 2x2, or 1x4?

Match the panel to the ceiling grid opening. A 2x4 panel fills a standard two-by-four troffer slot and is the most common office size. A 2x2 panel fits a square grid cell. A 1x4 panel suits corridors and narrow bays. Confirm the grid tee spacing before ordering.

What's the difference between a backlit and edge-lit LED panel?

The LED placement differs. A backlit panel mounts LEDs across the back of the fixture, giving higher lumen output and a slightly thicker body at lower cost. An edge-lit panel runs LEDs along the frame edge through a light guide, producing a thin profile and even glow. Backlit is the commercial default.

How do LED flat panels mount in a ceiling?

Three methods cover most installs. A recessed (lay-in) panel drops directly into a suspended grid with no tools. A surface-mount panel uses a frame kit to attach to a solid drywall ceiling. A suspended panel hangs from cables for open or high ceilings. Most grid panels are lay-in.

How many watts and lumens does a 2x4 LED panel produce?

A 2x4 LED flat panel typically draws 30 to 72 watts and delivers 4,000 to 9,000 lumens, replacing a two- or three-lamp fluorescent troffer. Many use selectable wattage so one fixture covers several output levels. Compare lumens and efficacy (lm/W), not watts alone, when sizing a space.

Are LED flat panels dimmable and color-selectable?

Most commercial panels are both. Standard models include 0-10V dimming for use with a compatible LED dimmer or building control. Selectable CCT panels switch between 3500K, 4000K, and 5000K with an onboard toggle, so one SKU covers multiple color temperatures. Some add selectable wattage on the same switch.

Do LED panels come with emergency battery backup?

Many do, as a factory option. An emergency-battery panel keeps a portion of the output lit for 90 minutes during a power loss, meeting egress-lighting requirements. The battery is built into the fixture, so no separate unit is needed. Specify the EM version when emergency coverage is required.

Building out the ceiling? Compare recessed alternatives in Troffers, add code-required egress with Emergency & Exit lighting, power the run with LED Drivers, and dial output using LED Dimmers.
